RHBA-2012:0319 - gnutls bug fix update

Synopsis

gnutls bug fix update

Type/Severity

Bug Fix Advisory (none)

Topic

Updated gnutls packages that fix one bug are now available for Red Hat Enterprise Linux 5.

Description

The gnutls package provides the GNU Transport Layer Security (GnuTLS) library, which provides a secure layer over a transport layer using protocols such as TLS, SSL and DTLS.

This update fixes the following bug:

  • Under certain circumstances, a NULL pointer could have been dereferenced in the GnuTLS library. This caused TLS clients, such as the rsyslog utility, to terminate unexpectedly with a segmentation fault. This update adds a test condition ensuring that a NULL pointer can no longer be dereferenced and TLS clients no longer crash. (BZ#789041)

All users of gnutls are advised to upgrade to these updated packages, which fix this bug. All applications linked with the GnuTLS library must be restarted (or the system rebooted) in order for this update to take effect.

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at This content is not included.http://kbase.redhat.com/faq/docs/DOC-11259
