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
http://kbase.redhat.com/faq/FAQ_58_10188
5. Bugs fixed (http://bugzilla.redhat.com/):
447461 - CVE-2008-1948 GNUTLS-SA-2008-1-1 GnuTLS buffer overflow
447462 - CVE-2008-1949 GNUTLS-SA-2008-1-2 GnuTLS null-pointer dereference
447463 - CVE-2008-1950 GNUTLS-SA-2008-1-3 GnuTLS memory overread flaw
