NONE Summary
The TLS protocol 1.2 and earlier, when a DHE_EXPORT ciphersuite is enabled on a server but not on a client, does not properly convey a DHE_EXPORT choice, which allows man-in-the-middle attackers to conduct cipher-downgrade attacks by rewriting a ClientHello with DHE replaced by DHE_EXPORT and then rewriting a ServerHello with DHE_EXPORT replaced by DHE, aka the "Logjam" issue.
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Signature Spoofing by Key Recreation An attacker obtains an authoritative or reputable signer's private signature key by exploiting a cryptographic weakness in the signature algorithm or pseudorandom number generation and then uses this key to forge signatures from the original signer to mislead a victim into performing actions that benefit the attacker.

NASL family CentOS Local Security Checks NASL id CENTOS_RHSA-2015-1072.NASL description Updated openssl packages that fix one security issue are now available for Red Hat Enterprise Linux 6 and 7. Red Hat Product Security has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols, as well as a full-strength, general purpose cryptography library. A flaw was found in the way the TLS protocol composes the Diffie-Hellman (DH) key exchange. A man-in-the-middle attacker could use this flaw to force the use of weak 512 bit export-grade keys during the key exchange, allowing them do decrypt all traffic. (CVE-2015-4000) Note: This update forces the TLS/SSL client implementation in OpenSSL to reject DH key sizes below 768 bits, which prevents sessions to be downgraded to export-grade keys. Future updates may raise this limit to 1024 bits. All openssl users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. For the update to take effect, all services linked to the OpenSSL library must be restarted, or the system rebooted. last seen 2020-06-01 modified 2020-06-02 plugin id 83994 published 2015-06-05 reporter This script is Copyright (C) 2015-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/83994 title CentOS 6 / 7 : openssl (CESA-2015:1072) (Logjam) code # # (C) Tenable Network Security, Inc. # # The descriptive text and package checks in this plugin were # extracted from Red Hat Security Advisory RHSA-2015:1072 and # CentOS Errata and Security Advisory 2015:1072 respectively. # include("compat.inc"); if (description) { script_id(83994); script_version("2.14"); script_cvs_date("Date: 2020/01/02"); script_cve_id("CVE-2015-4000"); script_bugtraq_id(74733); script_xref(name:"RHSA", value:"2015:1072"); script_name(english:"CentOS 6 / 7 : openssl (CESA-2015:1072) (Logjam)"); script_summary(english:"Checks rpm output for the updated packages"); script_set_attribute( attribute:"synopsis", value:"The remote CentOS host is missing one or more security updates." ); script_set_attribute( attribute:"description", value: "Updated openssl packages that fix one security issue are now available for Red Hat Enterprise Linux 6 and 7.

An attacker could use this flaw to downgrade a DHE connection to use export-grade key sizes, which could then be broken by sufficient pre-computation. This can lead to a passive man-in-the-middle attack in which the attacker is able to decrypt all traffic. (CVE-2015-4000) An out-of-bounds read flaw was found in the X509_cmp_time() function of OpenSSL, which is used to test the expiry dates of SSL/TLS certificates. An attacker could possibly use a specially crafted SSL/TLS certificate or CRL (Certificate Revocation List), which when parsed by an application would cause that application to crash. (CVE-2015-1789) A NULL pointer dereference was found in the way OpenSSL handled certain PKCS#7 inputs. An attacker able to make an application using OpenSSL verify, decrypt, or parse a specially crafted PKCS#7 input could cause that application to crash. TLS/SSL clients and servers using OpenSSL were not affected by this flaw. (CVE-2015-1790) A race condition was found in the session handling code of OpenSSL. An attacker could cause a multi-threaded SSL/TLS server to crash. (CVE-2015-1791) A denial of service flaw was found in OpenSSL in the way it verified certain signed messages using CMS (Cryptographic Message Syntax). A remote attacker could cause an application using OpenSSL to use excessive amounts of memory by sending a specially crafted message for verification. (CVE-2015-1792) An invalid-free flaw was found in the way OpenSSL handled certain DTLS handshake messages. A malicious DTLS client or server could send a specially crafted message to the peer, which could cause the application to crash or potentially cause arbitrary code execution. (CVE-2014-8176) A regression was found in the ssleay_rand_bytes() function. This could lead a multi-threaded application to crash.

Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The java-1.6.0-openjdk packages provide the OpenJDK 6 Java Runtime Environment and the OpenJDK 6 Java Software Development Kit. Multiple flaws were discovered in the 2D, CORBA, JMX, Libraries and RMI components in OpenJDK. An untrusted Java application or applet could use these flaws to bypass Java sandbox restrictions. (CVE-2015-4760, CVE-2015-2628, CVE-2015-4731, CVE-2015-2590, CVE-2015-4732, CVE-2015-4733) A flaw was found in the way the Libraries component of OpenJDK verified Online Certificate Status Protocol (OCSP) responses. An OCSP response with no nextUpdate date specified was incorrectly handled as having unlimited validity, possibly causing a revoked X.509 certificate to be interpreted as valid. (CVE-2015-4748) It was discovered that the JCE component in OpenJDK failed to use constant time comparisons in multiple cases. An attacker could possibly use these flaws to disclose sensitive information by measuring the time used to perform operations using these non-constant time comparisons. (CVE-2015-2601) A flaw was found in the RC4 encryption algorithm. When using certain keys for RC4 encryption, an attacker could obtain portions of the plain text from the cipher text without the knowledge of the encryption key. (CVE-2015-2808) Note: With this update, OpenJDK now disables RC4 TLS/SSL cipher suites by default to address the CVE-2015-2808 issue. Refer to Red Hat Bugzilla bug 1207101, linked to in the References section, for additional details about this change. A flaw was found in the way the TLS protocol composed the Diffie-Hellman (DH) key exchange. A man-in-the-middle attacker could use this flaw to force the use of weak 512 bit export-grade keys during the key exchange, allowing them to decrypt all traffic. (CVE-2015-4000) Note: This update forces the TLS/SSL client implementation in OpenJDK to reject DH key sizes below 768 bits, which prevents sessions to be downgraded to export-grade keys. Refer to Red Hat Bugzilla bug 1223211, linked to in the References section, for additional details about this change. It was discovered that the JNDI component in OpenJDK did not handle DNS resolutions correctly. An attacker able to trigger such DNS errors could cause a Java application using JNDI to consume memory and CPU time, and possibly block further DNS resolution. (CVE-2015-4749) Multiple information leak flaws were found in the JMX and 2D components in OpenJDK. An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions. (CVE-2015-2621, CVE-2015-2632) A flaw was found in the way the JSSE component in OpenJDK performed X.509 certificate identity verification when establishing a TLS/SSL connection to a host identified by an IP address. In certain cases, the certificate was accepted as valid if it was issued for a host name to which the IP address resolves rather than for the IP address. (CVE-2015-2625) All users of java-1.6.0-openjdk are advised to upgrade to these updated packages, which resolve these issues.

Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The java-1.8.0-openjdk packages provide the OpenJDK 8 Java Runtime Environment and the OpenJDK 8 Java Software Development Kit. Multiple flaws were discovered in the 2D, CORBA, JMX, Libraries and RMI components in OpenJDK. An untrusted Java application or applet could use these flaws to bypass Java sandbox restrictions. (CVE-2015-4760, CVE-2015-2628, CVE-2015-4731, CVE-2015-2590, CVE-2015-4732, CVE-2015-4733) A flaw was found in the way the Libraries component of OpenJDK verified Online Certificate Status Protocol (OCSP) responses. An OCSP response with no nextUpdate date specified was incorrectly handled as having unlimited validity, possibly causing a revoked X.509 certificate to be interpreted as valid. (CVE-2015-4748) It was discovered that the JCE component in OpenJDK failed to use constant time comparisons in multiple cases. An attacker could possibly use these flaws to disclose sensitive information by measuring the time used to perform operations using these non-constant time comparisons. (CVE-2015-2601) It was discovered that the GCM (Galois Counter Mode) implementation in the Security component of OpenJDK failed to properly perform a null check. This could cause the Java Virtual Machine to crash when an application performed encryption using a block cipher in the GCM mode. (CVE-2015-2659) A flaw was found in the RC4 encryption algorithm. When using certain keys for RC4 encryption, an attacker could obtain portions of the plain text from the cipher text without the knowledge of the encryption key. (CVE-2015-2808) Note: With this update, OpenJDK now disables RC4 TLS/SSL cipher suites by default to address the CVE-2015-2808 issue. Refer to Red Hat Bugzilla bug 1207101, linked to in the References section, for additional details about this change. A flaw was found in the way the TLS protocol composed the Diffie-Hellman (DH) key exchange. A man-in-the-middle attacker could use this flaw to force the use of weak 512 bit export-grade keys during the key exchange, allowing them do decrypt all traffic. (CVE-2015-4000) Note: This update forces the TLS/SSL client implementation in OpenJDK to reject DH key sizes below 768 bits, which prevents sessions to be downgraded to export-grade keys. Refer to Red Hat Bugzilla bug 1223211, linked to in the References section, for additional details about this change. It was discovered that the JNDI component in OpenJDK did not handle DNS resolutions correctly. An attacker able to trigger such DNS errors could cause a Java application using JNDI to consume memory and CPU time, and possibly block further DNS resolution. (CVE-2015-4749) Multiple information leak flaws were found in the JMX and 2D components in OpenJDK. An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions. (CVE-2015-2621, CVE-2015-2632) A flaw was found in the way the JSSE component in OpenJDK performed X.509 certificate identity verification when establishing a TLS/SSL connection to a host identified by an IP address. In certain cases, the certificate was accepted as valid if it was issued for a host name to which the IP address resolves rather than for the IP address. (CVE-2015-2625) Multiple insecure temporary file use issues were found in the way the Hotspot component in OpenJDK created performance statistics and error log files. A local attacker could possibly make a victim using OpenJDK overwrite arbitrary files using a symlink attack.

This could weaken the cryptographic protections provided by NSS. However, NSS implements RSA-CRT leak hardening, so RSA private keys are not directly disclosed by this issue. - CVE-2016-1978 Eric Rescorla discovered a use-after-free vulnerability in the implementation of ECDH-based TLS handshakes, with unknown consequences. - CVE-2016-1979 Tim Taubert discovered a use-after-free vulnerability in ASN.1 DER processing, with application-specific impact. - CVE-2016-2834 Tyson Smith and Jed Davis discovered unspecified memory-safety bugs in NSS. In addition, the NSS library did not ignore environment variables in processes which underwent a SUID/SGID/AT_SECURE transition at process start.

Red Hat Product Security has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols, as well as a full-strength, general purpose cryptography library. A flaw was found in the way the TLS protocol composes the Diffie-Hellman (DH) key exchange. A man-in-the-middle attacker could use this flaw to force the use of weak 512 bit export-grade keys during the key exchange, allowing them do decrypt all traffic. (CVE-2015-4000) Note: This update forces the TLS/SSL client implementation in OpenSSL to reject DH key sizes below 768 bits, which prevents sessions to be downgraded to export-grade keys. Future updates may raise this limit to 1024 bits. All openssl users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. For the update to take effect, all services linked to the OpenSSL library must be restarted, or the system rebooted. last seen 2020-06-01 modified 2020-06-02 plugin id 84003 published 2015-06-05 reporter This script is Copyright (C) 2015-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/84003 title Oracle Linux 6 / 7 : openssl (ELSA-2015-1072) (Logjam) NASL family General NASL id PCI_WEAK_DH_UNDER_2048.NASL description At least one of the services on the remote host supports a Diffie-Hellman key exchange using a public modulus smaller than 2048 bits.

Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols, as well as a full-strength, general purpose cryptography library. An out-of-bounds read flaw was found in the X509_cmp_time() function of OpenSSL. A specially crafted X.509 certificate or a Certificate Revocation List (CRL) could possibly cause a TLS/SSL server or client using OpenSSL to crash. (CVE-2015-1789) A NULL pointer dereference was found in the way OpenSSL handled certain PKCS#7 inputs. A specially crafted PKCS#7 input with missing EncryptedContent data could cause an application using OpenSSL to crash. (CVE-2015-1790) A flaw was found in the way the TLS protocol composes the Diffie-Hellman (DH) key exchange. A man-in-the-middle attacker could use this flaw to force the use of weak 512 bit export-grade keys during the key exchange, allowing them to decrypt all traffic. (CVE-2015-4000) Note: This update forces the TLS/SSL client implementation in OpenSSL to reject DH key sizes below 768 bits, which prevents sessions to be downgraded to export-grade keys. Future updates may raise this limit to 1024 bits. Red Hat would like to thank the OpenSSL project for reporting CVE-2015-1789 and CVE-2015-1790. Upstream acknowledges Robert Swiecki and Hanno Bock as the original reporters of CVE-2015-1789, and Michal Zalewski as the original reporter of CVE-2015-1790. All openssl users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. For the update to take effect, all services linked to the OpenSSL library must be restarted, or the system rebooted. last seen 2020-06-01 modified 2020-06-02 plugin id 84467 published 2015-06-30 reporter This script is Copyright (C) 2015-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/84467 title RHEL 5 : openssl (RHSA-2015:1197) (Logjam) NASL family Debian Local Security Checks NASL id DEBIAN_DSA-3287.NASL description Multiple vulnerabilities were discovered in OpenSSL, a Secure Sockets Layer toolkit. - CVE-2014-8176 Praveen Kariyanahalli, Ivan Fratric and Felix Groebert discovered that an invalid memory free could be triggered when buffering DTLS data. This could allow remote attackers to cause a denial of service (crash) or potentially execute arbitrary code. This issue only affected the oldstable distribution (wheezy). - CVE-2015-1788 Joseph Barr-Pixton discovered that an infinite loop could be triggered due to incorrect handling of malformed ECParameters structures. This could allow remote attackers to cause a denial of service. - CVE-2015-1789 Robert Swiecki and Hanno Bock discovered that the X509_cmp_time function could read a few bytes out of bounds. This could allow remote attackers to cause a denial of service (crash) via crafted certificates and CRLs. - CVE-2015-1790 Michal Zalewski discovered that the PKCS#7 parsing code did not properly handle missing content which could lead to a NULL pointer dereference. This could allow remote attackers to cause a denial of service (crash) via crafted ASN.1-encoded PKCS#7 blobs. - CVE-2015-1791 Emilia Kasper discovered that a race condition could occur due to incorrect handling of NewSessionTicket in a multi-threaded client, leading to a double free. This could allow remote attackers to cause a denial of service (crash). - CVE-2015-1792 Johannes Bauer discovered that the CMS code could enter an infinite loop when verifying a signedData message, if presented with an unknown hash function OID. This could allow remote attackers to cause a denial of service.

An untrusted Java application or applet could use these flaws to bypass Java sandbox restrictions. (CVE-2015-4760 , CVE-2015-2628 , CVE-2015-4731 , CVE-2015-2590 , CVE-2015-4732 , CVE-2015-4733) A flaw was found in the way the Libraries component of OpenJDK verified Online Certificate Status Protocol (OCSP) responses. An OCSP response with no nextUpdate date specified was incorrectly handled as having unlimited validity, possibly causing a revoked X.509 certificate to be interpreted as valid. (CVE-2015-4748) It was discovered that the JCE component in OpenJDK failed to use constant time comparisons in multiple cases. An attacker could possibly use these flaws to disclose sensitive information by measuring the time used to perform operations using these non-constant time comparisons. (CVE-2015-2601) A flaw was found in the RC4 encryption algorithm. When using certain keys for RC4 encryption, an attacker could obtain portions of the plain text from the cipher text without the knowledge of the encryption key. (CVE-2015-2808) Please note that with this update, OpenJDK now disables RC4 TLS/SSL cipher suites by default to address the CVE-2015-2808 issue. A flaw was found in the way the TLS protocol composed the Diffie-Hellman (DH) key exchange. A man-in-the-middle attacker could use this flaw to force the use of weak 512 bit export-grade keys during the key exchange, allowing them do decrypt all traffic. (CVE-2015-4000) Please note that this update forces the TLS/SSL client implementation in OpenJDK to reject DH key sizes below 768 bits, which prevents sessions to be downgraded to export-grade keys. It was discovered that the JNDI component in OpenJDK did not handle DNS resolutions correctly. An attacker able to trigger such DNS errors could cause a Java application using JNDI to consume memory and CPU time, and possibly block further DNS resolution. (CVE-2015-4749) Multiple information leak flaws were found in the JMX and 2D components in OpenJDK. An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions. (CVE-2015-2621 , CVE-2015-2632) A flaw was found in the way the JSSE component in OpenJDK performed X.509 certificate identity verification when establishing a TLS/SSL connection to a host identified by an IP address. In certain cases, the certificate was accepted as valid if it was issued for a host name to which the IP address resolves rather than for the IP address.

Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols, as well as a full-strength, general purpose cryptography library. An out-of-bounds read flaw was found in the X509_cmp_time() function of OpenSSL. A specially crafted X.509 certificate or a Certificate Revocation List (CRL) could possibly cause a TLS/SSL server or client using OpenSSL to crash. (CVE-2015-1789) A NULL pointer dereference was found in the way OpenSSL handled certain PKCS#7 inputs. A specially crafted PKCS#7 input with missing EncryptedContent data could cause an application using OpenSSL to crash. (CVE-2015-1790) A flaw was found in the way the TLS protocol composes the Diffie-Hellman (DH) key exchange. A man-in-the-middle attacker could use this flaw to force the use of weak 512 bit export-grade keys during the key exchange, allowing them to decrypt all traffic. (CVE-2015-4000) Note: This update forces the TLS/SSL client implementation in OpenSSL to reject DH key sizes below 768 bits, which prevents sessions to be downgraded to export-grade keys. Future updates may raise this limit to 1024 bits. Red Hat would like to thank the OpenSSL project for reporting CVE-2015-1789 and CVE-2015-1790. Upstream acknowledges Robert Swiecki and Hanno Bock as the original reporters of CVE-2015-1789, and Michal Zalewski as the original reporter of CVE-2015-1790. All openssl users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. For the update to take effect, all services linked to the OpenSSL library must be restarted, or the system rebooted. last seen 2020-06-01 modified 2020-06-02 plugin id 84485 published 2015-07-01 reporter This script is Copyright (C) 2015-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/84485 title Oracle Linux 5 : openssl (ELSA-2015-1197) (Logjam) NASL family CentOS Local Security Checks NASL id CENTOS_RHSA-2015-1526.NASL description Updated java-1.6.0-openjdk packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5, 6, and 7.

An OCSP response with no nextUpdate date specified was incorrectly handled as having unlimited validity, possibly causing a revoked X.509 certificate to be interpreted as valid. (CVE-2015-4748) It was discovered that the JCE component in OpenJDK failed to use constant time comparisons in multiple cases. An attacker could possibly use these flaws to disclose sensitive information by measuring the time used to perform operations using these non-constant time comparisons. (CVE-2015-2601) A flaw was found in the RC4 encryption algorithm. When using certain keys for RC4 encryption, an attacker could obtain portions of the plain text from the cipher text without the knowledge of the encryption key. (CVE-2015-2808) Note: With this update, OpenJDK now disables RC4 TLS/SSL cipher suites by default to address the CVE-2015-2808 issue.

It was discovered that the JNDI component in OpenJDK did not handle DNS resolutions correctly. An attacker able to trigger such DNS errors could cause a Java application using JNDI to consume memory and CPU time, and possibly block further DNS resolution. (CVE-2015-4749) Multiple information leak flaws were found in the JMX and 2D components in OpenJDK. An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions. (CVE-2015-2621, CVE-2015-2632) A flaw was found in the way the JSSE component in OpenJDK performed X.509 certificate identity verification when establishing a TLS/SSL connection to a host identified by an IP address. In certain cases, the certificate was accepted as valid if it was issued for a host name to which the IP address resolves rather than for the IP address.

It is, therefore, affected by the following vulnerabilities : - A security feature bypass vulnerability, known as FREAK (Factoring attack on RSA-EXPORT Keys), exists due to the support of weak EXPORT_RSA cipher suites with keys less than or equal to 512 bits. A man-in-the-middle attacker may be able to downgrade the SSL/TLS connection to use EXPORT_RSA cipher suites which can be factored in a short amount of time, allowing the attacker to intercept and decrypt the traffic. (CVE-2015-0204) - A denial of service vulnerability exists when processing an ECParameters structure due to an infinite loop that occurs when a specified curve is over a malformed binary polynomial field. A remote attacker can exploit this to perform a denial of service against any system that processes public keys, certificate requests, or certificates. This includes TLS clients and TLS servers with client authentication enabled. (CVE-2015-1788) - A privilege escalation vulnerability exists due to an untrusted search path flaw. A local attacker can exploit this, via a specially crafted library that is loaded by a setuid or setgid process, to gain elevated privileges on the system. (CVE-2015-1947) - A security feature bypass vulnerability exists, known as Bar Mitzvah, due to improper combination of state data with key data by the RC4 cipher algorithm during the initialization phase. A man-in-the-middle attacker can exploit this, via a brute-force attack using LSB values, to decrypt the traffic. (CVE-2015-2808) - A man-in-the-middle vulnerability, known as Logjam, exists due to a flaw in the SSL/TLS protocol. A remote attacker can exploit this flaw to downgrade connections using ephemeral Diffie-Hellman key exchange to 512-bit export-grade cryptography.

It is, therefore, affected by multiple vulnerabilities : - A security downgrade vulnerability exists due to a flaw in Network Security Services (NSS). When a client allows for a ECDHE_ECDSA exchange, but the server does not send a ServerKeyExchange message, the NSS client will take the EC key from the ECDSA certificate. A remote attacker can exploit this to silently downgrade the exchange to a non-forward secret mixed-ECDH exchange. (CVE-2015-2721) - Multiple user-after-free errors exist when using an XMLHttpRequest object in concert with either shared or dedicated workers. A remote attacker can exploit this to cause a denial of service condition. (CVE-2015-2722, CVE-2015-2733) - Multiple memory corruption issues exist that allow an attacker to cause a denial of service condition or potentially execute arbitrary code. (CVE-2015-2724, CVE-2015-2725) - A security bypass vulnerability exists due to a failure to preserve context restrictions. A remote attacker can exploit this, via a crafted web site that is accessed with unspecified mouse and keyboard actions, to read arbitrary files or execute arbitrary JavaScript code.

Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The java-1.7.0-openjdk packages provide the OpenJDK 7 Java Runtime Environment and the OpenJDK 7 Java Software Development Kit. Multiple flaws were discovered in the 2D, CORBA, JMX, Libraries and RMI components in OpenJDK. An untrusted Java application or applet could use these flaws to bypass certain Java sandbox restrictions. (CVE-2015-4760, CVE-2015-2628, CVE-2015-4731, CVE-2015-2590, CVE-2015-4732, CVE-2015-4733) A flaw was found in the way the Libraries component of OpenJDK verified Online Certificate Status Protocol (OCSP) responses. An OCSP response with no nextUpdate date specified was incorrectly handled as having unlimited validity, possibly causing a revoked X.509 certificate to be interpreted as valid. (CVE-2015-4748) It was discovered that the JCE component in OpenJDK failed to use constant time comparisons in multiple cases. An attacker could possibly use these flaws to disclose sensitive information by measuring the time used to perform operations using these non-constant time comparisons. (CVE-2015-2601) A flaw was found in the RC4 encryption algorithm. When using certain keys for RC4 encryption, an attacker could obtain portions of the plain text from the cipher text without the knowledge of the encryption key. (CVE-2015-2808) Note: With this update, OpenJDK now disables RC4 SSL/TLS cipher suites by default to address the CVE-2015-2808 issue. Refer to Red Hat Bugzilla bug 1207101, linked to in the References section, for additional details about this change. A flaw was found in the way the TLS protocol composed the Diffie-Hellman (DH) key exchange. A man-in-the-middle attacker could use this flaw to force the use of weak 512 bit export-grade keys during the key exchange, allowing them do decrypt all traffic. (CVE-2015-4000) Note: This update forces the TLS/SSL client implementation in OpenJDK to reject DH key sizes below 768 bits, which prevents sessions to be downgraded to export-grade keys. Refer to Red Hat Bugzilla bug 1223211, linked to in the References section, for additional details about this change. It was discovered that the JNDI component in OpenJDK did not handle DNS resolutions correctly. An attacker able to trigger such DNS errors could cause a Java application using JNDI to consume memory and CPU time, and possibly block further DNS resolution. (CVE-2015-4749) Multiple information leak flaws were found in the JMX and 2D components in OpenJDK. An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions. (CVE-2015-2621, CVE-2015-2632) A flaw was found in the way the JSSE component in OpenJDK performed X.509 certificate identity verification when establishing a TLS/SSL connection to a host identified by an IP address. In certain cases, the certificate was accepted as valid if it was issued for a host name to which the IP address resolves rather than for the IP address.

An OCSP response with no nextUpdate date specified was incorrectly handled as having unlimited validity, possibly causing a revoked X.509 certificate to be interpreted as valid. (CVE-2015-4748) It was discovered that the JCE component in OpenJDK failed to use constant time comparisons in multiple cases. An attacker could possibly use these flaws to disclose sensitive information by measuring the time used to perform operations using these non-constant time comparisons. (CVE-2015-2601) A flaw was found in the RC4 encryption algorithm. When using certain keys for RC4 encryption, an attacker could obtain portions of the plain text from the cipher text without the knowledge of the encryption key. (CVE-2015-2808) A flaw was found in the way the TLS protocol composed the Diffie-Hellman (DH) key exchange. A man-in-the-middle attacker could use this flaw to force the use of weak 512 bit export-grade keys during the key exchange, allowing them do decrypt all traffic. (CVE-2015-4000) It was discovered that the JNDI component in OpenJDK did not handle DNS resolutions correctly. An attacker able to trigger such DNS errors could cause a Java application using JNDI to consume memory and CPU time, and possibly block further DNS resolution. (CVE-2015-4749) Multiple information leak flaws were found in the JMX and 2D components in OpenJDK. An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions. (CVE-2015-2621, CVE-2015-2632) A flaw was found in the way the JSSE component in OpenJDK performed X.509 certificate identity verification when establishing a TLS/SSL connection to a host identified by an IP address. In certain cases, the certificate was accepted as valid if it was issued for a host name to which the IP address resolves rather than for the IP address. (CVE-2015-2625) Note: If the web browser plug-in provided by the icedtea-web package was installed, the issues exposed via Java applets could have been exploited without user interaction if a user visited a malicious website. All running instances of OpenJDK Java must be restarted for the update to take effect. last seen 2020-03-18 modified 2015-07-16 plugin id 84792 published 2015-07-16 reporter This script is Copyright (C) 2015-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/84792 title Scientific Linux Security Update : java-1.7.0-openjdk on SL6.x, SL7.x i386/x86_64 (20150715) (Bar Mitzvah) (Logjam)
