High Nessus Plugin ID 106791
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionMeh Chang discovered that Exim incorrectly handled memory in certain decoding operations. A remote attacker could use this issue to cause Exim to crash, resulting in a denial of service, or possibly execute arbitrary code.
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 exim4-daemon-heavy and / or exim4-daemon-light packages.
