Low Nessus Plugin ID 100920
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionIt was discovered that Exim did not properly deallocate memory when processing certain command line arguments. A local attacker could use this in conjunction with another vulnerability to possibly execute arbitrary code and gain administrative privileges.
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.
