Summary

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

specially crafted file.

Software Description:

- evince: Document viewer

Details:

Felix Wilhelm discovered that Evince did not safely invoke tar when

handling tar comic book (cbt) files. An attacker could use this to

construct a malicious cbt comic book format file that, when opened

in Evince, executes arbitrary code. Please note that this update

disables support for cbt files in Evince.
