CentOS 5 : gnutls (CESA-2008:0489)
critical Nessus Plugin ID 43688

Synopsis
The remote CentOS host is missing one or more security updates.Description
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.
