| Descripción: | Description:
The remote host is missing updates announced in
advisory RHSA-2008:0492.
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:
Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
