Ubuntu 10.04 LTS / 12.04 LTS / 14.04 LTS / 14.10 : mutt vulnerability (USN-2440-1)
Medium Nessus Plugin ID 80027
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionJakub Wilk discovered that the write_one_header function in mutt did not properly handle newline characters at the beginning of a header.
An attacker could specially craft an email to cause mutt to crash, resulting in a denial of service.
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 mutt and / or mutt-patched packages.
