Summary

MIT Kerberos 5 (aka krb5) 1.7.x and 1.8.x through 1.8.3 does not properly determine the acceptability of checksums, which might allow remote attackers to forge GSS tokens, gain privileges, or have unspecified other impact via (1) an unkeyed checksum, (2) an unkeyed PAC checksum, or (3) a KrbFastArmoredReq checksum based on an RC4 key.

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.

    descriptionUpdated krb5 packages that fix multiple security issues and one bug are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team 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. Kerberos is a network authentication system which allows clients and servers to authenticate to each other using symmetric encryption and a trusted third party, the Key Distribution Center (KDC). Multiple checksum validation flaws were discovered in the MIT Kerberos implementation. A remote attacker could use these flaws to tamper with certain Kerberos protocol packets and, possibly, bypass authentication or authorization mechanisms and escalate their privileges. (CVE-2010-1323, CVE-2010-1324, CVE-2010-4020) Red Hat would like to thank the MIT Kerberos Team for reporting these issues. This update also fixes the following bug : * When attempting to perform PKINIT pre-authentication, if the client had more than one possible candidate certificate the client could fail to select the certificate and key to use. This usually occurred if certificate selection was configured to use the value of the keyUsage extension, or if any of the candidate certificates did not contain a subjectAltName extension. Consequently, the client attempted to perform pre-authentication using a different (usually password-based) mechanism. (BZ#644825) All krb5 users should upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, the krb5kdc daemon will be restarted automatically.

    descriptionIt was discovered that Kerberos did not properly determine the acceptability of certain checksums. A remote attacker could use certain checksums to alter the prompt message, modify a response to a Key Distribution Center (KDC) or forge a KRB-SAFE message. (CVE-2010-1323) It was discovered that Kerberos did not properly determine the acceptability of certain checksums. A remote attacker could use certain checksums to forge GSS tokens or gain privileges. This issue only affected Ubuntu 9.10, 10.04 LTS and 10.10. (CVE-2010-1324) It was discovered that Kerberos did not reject RC4 key-derivation checksums. An authenticated remote user could use this issue to forge AD-SIGNEDPATH or AD-KDC-ISSUED signatures and possibly gain privileges. This issue only affected Ubuntu 10.04 LTS and 10.10. (CVE-2010-4020) It was discovered that Kerberos did not properly restrict the use of TGT credentials for armoring TGS requests. A remote authenticated user could use this flaw to impersonate a client. This issue only affected Ubuntu 9.10. (CVE-2010-4021). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    descriptionUpdated krb5 packages that fix multiple security issues are now available for Red Hat Enterprise Linux 4 and 5. The Red Hat Security Response Team 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. Kerberos is a network authentication system which allows clients and servers to authenticate to each other using symmetric encryption and a trusted third party, the Key Distribution Center (KDC). Multiple checksum validation flaws were discovered in the MIT Kerberos implementation. A remote attacker could use these flaws to tamper with certain Kerberos protocol packets and, possibly, bypass authentication mechanisms in certain configurations using Single-use Authentication Mechanisms. (CVE-2010-1323) Red Hat would like to thank the MIT Kerberos Team for reporting these issues. All krb5 users should upgrade to these updated packages, which contain a backported patch to correct these issues. After installing the updated packages, the krb5kdc daemon will be restarted automatically.

    descriptionThe MIT Kerberos team reports : MIT krb incorrectly accepts an unkeyed checksum with DES session keys for version 2 (RFC 4121) of the GSS-API krb5 mechanism. An unauthenticated remote attacker can forge GSS tokens that are intended to be integrity-protected but unencrypted, if the targeted pre-existing application session uses a DES session key. MIT krb5 KDC incorrectly accepts RFC 3961 key-derivation checksums using RC4 keys when verifying the req-checksum in a KrbFastArmoredReq. An unauthenticated remote attacker has a 1/256 chance of swapping a client-issued KrbFastReq into a different KDC-REQ, if the armor key is RC4. The consequences are believed to be minor.

    descriptionThe Oracle Secure Global Desktop installed on the remote host is version 4.63 / 4.71 / 5.1 / 5.2. It is, therefore, affected by the following vulnerabilities : - A security bypass vulnerability exists in Kerberos 5 due to a failure to properly determine the acceptability of checksums. A remote attacker can exploit this to forge tokens or gain privileges by using an unkeyed checksum. (CVE-2010-1324) - A NULL pointer deference flaw exists in the function bdfReadCharacters() in file bdfread.c of the X.Org libXfont module due to improper handling of non-readable character bitmaps. An authenticated, remote attacker, using a crafted BDF font file, can exploit this to cause a denial of service or execute arbitrary code. (CVE-2015-1803) - An out-of-bounds read/write error exists in the SProcXFixesSelectSelectionInput() function in the XFixes extension. A remote, authenticated attacker, using a crafted length value, can exploit this to cause a denial of service or execute arbitrary code. (CVE-2014-8102) - A remote attacker, by using a crafted string length value in an XkbSetGeometry request, can gain access to sensitive information from process memory or cause a denial of service. (CVE-2015-0255) - An invalid read error exists in the ASN1_TYPE_cmp() function due to improperly performed boolean-type comparisons. A remote attacker can exploit this, via a crafted X.509 certificate to an endpoint that uses the certificate-verification feature, to cause an invalid read operation, resulting in a denial of service. (CVE-2015-0286) - A denial of service vulnerability exists in Apache Tomcat due to improper handling of HTTP responses that occurs before finishing reading an entire request body. A remote attacker can exploit this by using a crafted series of aborted upload attempts. (CVE-2014-0230) - A denial of service vulnerability exists in Apache Tomcat in ChunkedInputFilter.java due to improper handling of attempts to read data after an error has occurred. A remote attacker can exploit this by streaming data with malformed chunked-transfer encoding. (CVE-2014-0227) - A NULL pointer dereference flaw exists in the dtls1_get_record() function when handling DTLS messages. A remote attacker, using a specially crafted DTLS message, can cause a denial of service. (CVE-2014-3571) - An unspecified flaw exists that is related to the JServer subcomponent. A remote attacker can exploit this to impact confidentiality and integrity. No further details have been provided. (CVE-2015-2581)

    NASL idORACLELINUX_ELSA-2010-0926.NASL
    descriptionFrom Red Hat Security Advisory 2010:0926 : Updated krb5 packages that fix multiple security issues are now available for Red Hat Enterprise Linux 4 and 5. The Red Hat Security Response Team 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. Kerberos is a network authentication system which allows clients and servers to authenticate to each other using symmetric encryption and a trusted third party, the Key Distribution Center (KDC). Multiple checksum validation flaws were discovered in the MIT Kerberos implementation. A remote attacker could use these flaws to tamper with certain Kerberos protocol packets and, possibly, bypass authentication mechanisms in certain configurations using Single-use Authentication Mechanisms. (CVE-2010-1323) Red Hat would like to thank the MIT Kerberos Team for reporting these issues. All krb5 users should upgrade to these updated packages, which contain a backported patch to correct these issues. After installing the updated packages, the krb5kdc daemon will be restarted automatically.

    NASL idVMWARE_VMSA-2011-0007.NASL
    descriptiona. ESX/ESXi Socket Exhaustion By sending malicious network traffic to an ESXi or ESX host an attacker could exhaust the available sockets which would prevent further connections to the host. In the event a host becomes inaccessible its virtual machines will continue to run and have network connectivity but a reboot of the ESXi or ESX host may be required in order to be able to connect to the host again. ESXi and ESX hosts may intermittently lose connectivity caused by applications that do not correctly close sockets. If this occurs an error message similar to the following may be written to the vpxa log : socket() returns -1 (Cannot allocate memory) An error message similar to the following may be written to the vmkernel logs : socreate(type=2, proto=17) failed with error 55 VMware would like to thank Jimmy Scott at inet-solutions.be for reporting this issue to us. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2011-1785 to this issue. b. Likewise package update Updates to the vmware-esx-likewise-openldap and vmware-esx-likewise-krb5 packages address several security issues. One of the vulnerabilities is specific to Likewise while the other vulnerabilities are present in the MIT version of krb5. An incorrect assert() call in Likewise may lead to a termination of the Likewise-open lsassd service if a username with an illegal byte sequence is entered for user authentication when logging in to the Active Directory domain of the ESXi/ESX host. This would lead to a denial of service. The MIT-krb5 vulnerabilities are detailed in MITKRB5-SA-2010-007. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2011-1786 (Likewise-only issue), CVE-2010-1324, CVE-2010-1323, CVE-2010-4020, CVE-2010-4021 to these issues. c. ESX third-party update for Service Console kernel The Service Console kernel is updated to include a fix for a security issue. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-2240 to this issue.

    descriptionMultiple vulnerabilities were discovered and corrected in krb5 : An unauthenticated remote attacker could alter a SAM-2 challenge, affecting the prompt text seen by the user or the kind of response sent to the KDC. Under some circumstances, this can negate the incremental security benefit of using a single-use authentication mechanism token. An unauthenticated remote attacker has a 1/256 chance of forging KRB-SAFE messages in an application protocol if the targeted pre-existing session uses an RC4 session key. Few application protocols use KRB-SAFE messages (CVE-2010-1323). An unauthenticated remote attacker can forge GSS tokens that are intended to be integrity-protected but unencrypted, if the targeted pre-existing application session uses a DES session key. An authenticated remote attacker can forge PACs if using a KDC that does not filter client-provided PAC data. This can result in privilege escalation against a service that relies on PAC contents to make authorization decisions. An unauthenticated remote attacker has a 1/256 chance of swapping a client-issued KrbFastReq into a different KDC-REQ, if the armor key is RC4. The consequences are believed to be minor (CVE-2010-1324). An authenticated remote attacker that controls a legitimate service principal has a 1/256 chance of forging the AD-SIGNEDPATH signature if the TGT key is RC4, allowing it to use self-generated evidence tickets for S4U2Proxy, instead of tickets obtained from the user or with S4U2Self. Configurations using RC4 for the TGT key are believed to be rare. An authenticated remote attacker has a 1/256 chance of forging AD-KDC-ISSUED signatures on authdata elements in tickets having an RC4 service key, resulting in privilege escalation against a service that relies on these signatures. There are no known uses of the KDC-ISSUED authdata container at this time (CVE-2010-4020. An authenticated remote attacker that controls a legitimate service principal could obtain a valid service ticket to itself containing valid KDC-generated authorization data for a client whose TGS-REQ it has intercepted. The attacker could then use this ticket for S4U2Proxy to impersonate the targeted client even if the client never authenticated to the subverted service. The vulnerable configuration is believed to be rare (CVE-2010-4021). The updated packages have been patched to correct this issue.

    descriptionThe remote Solaris system is missing necessary patches to address security updates : - The merge_authdata function in kdc_authdata.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.8.x before 1.8.4 does not properly manage an index into an authorization-data list, which allows remote attackers to cause a denial of service (daemon crash), or possibly obtain sensitive information, spoof authorization, or execute arbitrary code, via a TGS request that triggers an uninitialized pointer dereference, as demonstrated by a request from a Windows Active Directory client. (CVE-2010-1322) - MIT Kerberos 5 (aka krb5) 1.3.x, 1.4.x, 1.5.x, 1.6.x, 1.7.x, and 1.8.x through 1.8.3 does not properly determine the acceptability of checksums, which might allow remote attackers to modify user-visible prompt text, modify a response to a Key Distribution Center (KDC), or forge a KRB-SAFE message via certain checksums that (1) are unkeyed or (2) use RC4 keys. (CVE-2010-1323) - MIT Kerberos 5 (aka krb5) 1.7.x and 1.8.x through 1.8.3 does not properly determine the acceptability of checksums, which might allow remote attackers to forge GSS tokens, gain privileges, or have unspecified other impact via (1) an unkeyed checksum, (2) an unkeyed PAC checksum, or (3) a KrbFastArmoredReq checksum based on an RC4 key. (CVE-2010-1324) - MIT Kerberos 5 (aka krb5) 1.8.x through 1.8.3 does not reject RC4 key-derivation checksums, which might allow remote authenticated users to forge a (1) AD-SIGNEDPATH or (2) AD-KDC-ISSUED signature, and possibly gain privileges, by leveraging the small key space that results from certain one-byte stream-cipher operations. (CVE-2010-4020) - The Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.7 does not properly restrict the use of TGT credentials for armoring TGS requests, which might allow remote authenticated users to impersonate a client by rewriting an inner request, aka a

    descriptionUpdated krb5 packages that fix multiple security issues are now available for Red Hat Enterprise Linux 4 and 5. The Red Hat Security Response Team 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. Kerberos is a network authentication system which allows clients and servers to authenticate to each other using symmetric encryption and a trusted third party, the Key Distribution Center (KDC). Multiple checksum validation flaws were discovered in the MIT Kerberos implementation. A remote attacker could use these flaws to tamper with certain Kerberos protocol packets and, possibly, bypass authentication mechanisms in certain configurations using Single-use Authentication Mechanisms. (CVE-2010-1323) Red Hat would like to thank the MIT Kerberos Team for reporting these issues. All krb5 users should upgrade to these updated packages, which contain a backported patch to correct these issues. After installing the updated packages, the krb5kdc daemon will be restarted automatically.
