Ubuntu 6.06 LTS / 8.04 LTS / 8.10 / 9.04 : libwmf vulnerability (USN-769-1)

High Nessus Plugin ID 38685


The remote Ubuntu host is missing one or more security-related patches.


Tavis Ormandy discovered that libwmf incorrectly used memory after it had been freed when using its embedded GD library. If a user or automated system were tricked into opening a crafted WMF file, an attacker could cause a denial of service or execute arbitrary code with privileges of the user invoking the program.

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.


Update the affected packages.
