Advisory: RHSA-2006:0207-10
Type: Security Advisory
Severity: Important
Issued on: 2006-02-10
Last updated on: 2006-02-10
Affected Products: Red Hat Desktop (v. 4)

CVEs (cve.mitre.org): CVE-2006-0645

Details

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. GNU TLS includes Libtasn1, a library developed for
ASN.1 structures management that includes DER encoding and decoding.

Several flaws were found in the way libtasn1 decodes DER. An attacker
could create a carefully crafted invalid X.509 certificate in such a way
that could trigger this flaw if parsed by an application that uses GNU TLS.
This could lead to a denial of service (application crash). It is not
certain if this issue could be escalated to allow arbitrary code execution.
The Common Vulnerabilities and Exposures project assigned the name
CVE-2006-0645 to this issue.

In Red Hat Enterprise Linux 4, the GNU TLS library is only used by the
Evolution client when connecting to an Exchange server or when publishing
calendar information to a WebDAV server.

Users are advised to upgrade to these updated packages, which contain a
backported patch from the GNU TLS maintainers to correct this issue.


Solution

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

This update is available via Red Hat Network. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
