USN-769-1: libwmf vulnerability

Releases

• Ubuntu 9.04
• Ubuntu 8.10
• Ubuntu 8.04
• Ubuntu 6.06

Packages

• libwmf -

Details

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.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 9.04

• libwmf0.2-7 - 0.2.8.4-6ubuntu1.1

Ubuntu 8.10

• libwmf0.2-7 - 0.2.8.4-6ubuntu0.8.10.1

Ubuntu 8.04

• libwmf0.2-7 - 0.2.8.4-6ubuntu0.8.04.1

Ubuntu 6.06

• libwmf0.2-7 - 0.2.8.3-3.1ubuntu0.2

In general, a standard system upgrade is sufficient to effect the
necessary changes.
