Scroller Ubuntu
Opening specially designed files in Evince on Ubuntu might lead to crashes or allow execution of arbitrary code, representing a considerable security risk.
Evince could be made to crash or run programs as your login if it opened a specially crafted file.

Summary

Evince could be made to crash or run programs as your login if it opened a

specially crafted file.

Software Description:

- evince: Document viewer

Details:

It was discovered that Evince did not properly parse AFM font files when

processing DVI files. If a user were tricked into opening a specially

crafted DVI file, an attacker could cause Evince to crash or potentially

execute arbitrary code with the privileges of the user invoking the

program.

In the default installation, attackers would be isolated by the Evince

AppArmor profile.
