Security Advisory Critical: gnutls security update

Advisory: RHSA-2008:0489-5
Type: Security Advisory
Severity: Critical
Issued on: 2008-05-20
Last updated on: 2008-05-20
Affected Products: RHEL Desktop Workstation (v. 5 client)
Red Hat Enterprise Linux (v. 5 server)
Red Hat Enterprise Linux Desktop (v. 5 client)
Red Hat Enterprise Linux EUS (v. 5.1.z server)
CVEs (cve.mitre.org): CVE-2008-1948
CVE-2008-1949
CVE-2008-1950

Details

Updated gnutls packages that fix several security issues are now available
for Red Hat Enterprise Linux 5.

This update has been rated as having critical security impact by the Red
Hat Security Response Team.

The GnuTLS Library provides support for cryptographic algorithms and
protocols such as TLS. GnuTLS includes libtasn1, a library developed for
ASN.1 structures management that includes DER encoding and decoding.

Flaws were found in the way GnuTLS handles malicious client connections. A
malicious remote client could send a specially crafted request to a service
using GnuTLS that could cause the service to crash. (CVE-2008-1948,
CVE-2008-1949, CVE-2008-1950)

We believe it is possible to leverage the flaw CVE-2008-1948 to execute
arbitrary code but have been unable to prove this at the time of releasing
this advisory. Red Hat Enterprise Linux 5 includes applications, such as
CUPS, that would be directly vulnerable to any such an exploit, however.
Consequently, we have assigned it critical severity.

Users of GnuTLS are advised to upgrade to these updated packages, which
contain a backported patch that corrects these issues.


Solution

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

This update is available via Red Hat Network. Details on how to use
