KDE kimgio: PCX handling buffer overflow

Background

KDE is a feature-rich graphical desktop environment for Linux and Unix-like Operating Systems. kimgio is the KDE image handler provided by kdelibs.

Description

kimgio fails to properly validate input when handling PCX files.

Impact

By enticing a user to load a specially-crafted PCX image in a KDE application, an attacker could execute arbitrary code.

Workaround

There is no known workaround at this time.

Resolution

All kdelibs users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose kde-base/kdelibs
