Synopsis: Important: gnutls security update Advisory ID: RHSA-2006:0207-01 Advisory URL: https://rhn.redhat.com/errata/RHSA-2006-0207.html Issue date: 2006-02-10 Updated on: 2006-02-10 Product: Red Hat Enterprise Linux CVE Names: CVE-2006-0645 - ---------------------------------------------------------------------
1. Summary:
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.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux Desktop version 4 - i386, x86_64 Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64
3. Problem description:
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.
4. 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.
