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...

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...
