Releases

• Ubuntu 15.04
• Ubuntu 14.10
• Ubuntu 14.04 ESM
• Ubuntu 12.04

Packages

• libwmf - Windows metafile conversion tools

Details

Fernando Muñoz and Stefan Cornelius discovered that libwmf incorrectly
handled certain malformed images. If a user or automated system were
tricked into opening a crafted image 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 15.04

• libwmf0.2-7 - 0.2.8.4-10.3ubuntu1.15.04.1

Ubuntu 14.10

• libwmf0.2-7 - 0.2.8.4-10.3ubuntu1.14.10.1

Ubuntu 14.04

• libwmf0.2-7 - 0.2.8.4-10.3ubuntu1.14.04.1

Ubuntu 12.04

• libwmf0.2-7 - 0.2.8.4-10ubuntu1.1

In general, a standard system update will make all the necessary changes.
