RHEL 4 : gnutls (RHSA-2008:0492)
critical Nessus Plugin ID 32429
Synopsis
The remote Red Hat 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 4.This update has been rated as having important 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 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.
Solution
Update the affected gnutls and / or gnutls-devel packages.See Also
