Ubuntu 5.10 : libcairo vulnerability (USN-265-1)
Medium Nessus Plugin ID 21151
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionWhen rendering glyphs, the cairo graphics rendering library did not check the maximum length of character strings. A request to display an excessively long string with cairo caused a program crash due to an X library error.
Mike Davis discovered that this could be turned into a Denial of Service attack in Evolution. An email with an attachment with very long lines caused Evolution to crash repeatedly until that email was manually removed from the mail folder.
This only affects Ubuntu 5.10. Previous Ubuntu releases did not use libcairo for text rendering.
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 libcairo2, libcairo2-dev and / or libcairo2-doc packages.
