GnuTLS Releases Security Update

GnuTLS has released security updates to address a vulnerability affecting certificate verification functions. An attacker could use a specially crafted X509 certificate to bypass validation checks, impersonate legitimate web sites or services, and perform man-in-the-middle attacks.

Many Linux distributions and other software which use GnuTLS are affected.

Updates available include:

• GnuTLS 2.12.x patch application
• GnuTLS 3.2.12 for the current stable branch
• GnuTLS 3.1.22 for the previous stable branch

Users and administrators are encouraged to review the GnuTLS Security Advisory GNUTLS-SA-2014-2 and apply the necessary updates to help mitigate the risk.
