Scientific Linux Security Update : gnutls on SL5.x i386/x86_64
Critical Nessus Plugin ID 60401
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionFlaws 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)
At this time we have not seen any code that is using this exploit. But in Scientific Linux 5 there are some applications, such as CUPS, that would be directly vulnerable if/when there is an exploit. Because of the potential threat we are labeling this critical.
SolutionUpdate the affected gnutls, gnutls-devel and / or gnutls-utils packages.
