Summary

The stream reading functions in lib/opencdk/read-packet.c in GnuTLS before 3.3.26 and 3.5.x before 3.5.8 allow remote attackers to cause a denial of service (out-of-memory error and crash) via a crafted OpenPGP certificate.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Overread Buffers
    An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.

    titleNewStart CGSL MAIN 4.05 : gnutls Multiple Vulnerabilities (NS-SA-2019-0109)
  • NASL familyRed Hat Local Security Checks
    NASL idREDHAT-RHSA-2017-2292.NASL
    descriptionAn update for gnutls is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The gnutls packages provide the GNU Transport Layer Security (GnuTLS) library, which implements cryptographic algorithms and protocols such as SSL, TLS, and DTLS. The following packages have been upgraded to a later upstream version: gnutls (3.3.26). (BZ#1378373) Security Fix(es) : * A double-free flaw was found in the way GnuTLS parsed certain X.509 certificates with Proxy Certificate Information extension. An attacker could create a specially crafted certificate which, when processed by an application compiled against GnuTLS, could cause that application to crash. (CVE-2017-5334) * Multiple flaws were found in the way gnutls processed OpenPGP certificates. An attacker could create specially crafted OpenPGP certificates which, when parsed by gnutls, would cause it to crash. (CVE-2017-5335, CVE-2017-5336, CVE-2017-5337, CVE-2017-7869) * A NULL pointer dereference flaw was found in the way GnuTLS processed ClientHello messages with status_request extension. A remote attacker could use this flaw to cause an application compiled with GnuTLS to crash. (CVE-2017-7507) * A flaw was found in the way GnuTLS validated certificates using OCSP responses. This could falsely report a certificate as valid under certain circumstances. (CVE-2016-7444) The CVE-2017-7507 issue was discovered by Hubert Kario (Red Hat QE BaseOS Security team). Additional Changes : For detailed information on changes in this release, see the Red Hat Enterprise Linux 7.4 Release Notes linked from the References section.

    NASL idEULEROS_SA-2017-1204.NASL
    descriptionAccording to the versions of the gnutls packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - A double-free flaw was found in the way GnuTLS parsed certain X.509 certificates with Proxy Certificate Information extension. An attacker could create a specially-crafted certificate which, when processed by an application compiled against GnuTLS, could cause that application to crash. (CVE-2017-5334) - Multiple flaws were found in the way gnutls processed OpenPGP certificates. An attacker could create specially crafted OpenPGP certificates which, when parsed by gnutls, would cause it to crash. (CVE-2017-5335, CVE-2017-5336, CVE-2017-5337, CVE-2017-7869) - A null pointer dereference flaw was found in the way GnuTLS processed ClientHello messages with status_request extension. A remote attacker could use this flaw to cause an application compiled with GnuTLS to crash. (CVE-2017-7507) - A flaw was found in the way GnuTLS validated certificates using OCSP responses. This could falsely report a certificate as valid under certain circumstances. (CVE-2016-7444) Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
