Red Hat Security Advisory

 

Synopsis: Important: gnutls security update

Advisory ID: RHSA-2008:0492-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2008-0492.html

Issue date: 2008-05-20

CVE Names: CVE-2008-1948 CVE-2008-1949 CVE-2008-1950

=====================================================================

 

1. Summary:

 

Updated gnutls packages that fix several security issues 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. Description:

 

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 4 does not ship with any

applications directly affected by this flaw. Third-party software which

runs on Red Hat Enterprise Linux 4 could, however, be affected by this

vulnerability. Consequently, we have assigned it important severity.

 

Users of GnuTLS are advised to upgrade to these updated packages, which

contain a backported patch that corrects these issues.

 

4. 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

the Red Hat Network to apply this update are available at
