High Nessus Plugin ID 78261
SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionIt was discovered that Rsyslog incorrectly handled invalid PRI values.
An attacker could use this issue to send malformed messages to the Rsyslog server and cause it to stop responding, resulting in a denial of service and possibly message loss. (CVE-2014-3634, CVE-2014-3683).
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected rsyslog package.
