USN-2865-1: GnuTLS vulnerability

Karthikeyan Bhargavan and Gaetan Leurent discovered that GnuTLS incorrectly allowed MD5 to be used for TLS 1.2 connections. If a remote attacker were able to perform a machine-in-the-middle attack, this flaw could be exploited to view sensitive information...

UBUNTU-CVE-2015-8313

GnuTLS incorrectly validates the first byte of padding in CBC modes...

Debian DSA-2981-1 : polarssl - security update

A flaw was discovered in PolarSSL, a lightweight crypto and SSL/TLS library, which can be exploited by a remote unauthenticated attacker to mount a denial of service against PolarSSL servers that offer GCM ciphersuites. Potentially clients are affected too if a malicious server decides to execute...

USN-2229-1 gnutls26 vulnerability

Joonas Kuorilehto discovered that GnuTLS incorrectly handled Server Hello messages. A malicious remote server or a machine-in-the-middle could use this issue to cause GnuTLS to crash, resulting in a denial of service, or possibly execute arbitrary code...

USN-2121-1: GnuTLS vulnerability

Suman Jana discovered that GnuTLS incorrectly handled version 1 intermediate certificates. This resulted in them being considered to be a valid CA certificate by default, which was contrary to documented behaviour...

Microsoft Windows multiple security vulnerabilities

Print spooler service code execution, XML library integer overflow and memory corruption, multiple .Net vulnerabilities, Win32K privilege escalation SSL/TLS library protection bypass, Open Data Protocol DoS...

GnuTLS insufficient cert verification

libcurl when built to use GnuTLS fails to verify that a peer's certificate has not already expired or has not yet become valid. This allows malicious servers to present certificates to libcurl that were not rejected properly. Notably, the CA certificate and common name checks are still in place...

Ubuntu 4.10 / 5.04 / 5.10 : libtasn1-2 vulnerability (USN-251-1)

Evgeny Legerov discovered a buffer overflow in the DER format decoding function of the libtasn library. This library is mainly used by the GNU TLS library; by sending a specially crafted X.509 certificate to a server which uses TLS encryption/authentication, a remote attacker could exploit this t...

Important: Red Hat Security Advisory: gnutls security update

Updated gnutls packages that fix a security issue are now available for Red Hat Enterprise Linux 4. This update has been rated as having important security impact by the Red Hat Security Response Team. The GNU TLS Library provides support for cryptographic algorithms and protocols such as TLS. GN...

Ubuntu 4.10 / 5.04 : gnutls11, gnutls10 vulnerability (USN-126-1)

A Denial of Service vulnerability was discovered in the GNU TLS library, which provides common cryptographic algorithms and is used by many applications in Ubuntu. Due to a missing sanity check of the padding length field, specially crafted ciphertext blocks caused an out of bounds memory access...

USN-126-1: GNU TLS library vulnerability

A Denial of Service vulnerability was discovered in the GNU TLS library, which provides common cryptographic algorithms and is used by many applications in Ubuntu. Due to a missing consistency check of the padding length field, specially crafted ciphertext blocks caused an out of bounds memory...
