Ubuntu 11.10 : lightdm vulnerability (USN-1382-1)
High Nessus Plugin ID 58223
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionAustin Clements discovered that Light Display Manager incorrectly leaked file descriptors to child processes. A local attacker can use this to bypass intended permissions and write to the log file, cause a denial of service, or possibly have another unknown impact.
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 packages.
