Package	Vulnerable versions	Unaffected versions	Architecture(s)
kde-base/kdelibs	< 3.3.2-r8	revision >= 3.2.3-r9, >= 3.3.2-r8	All supported architectures

Related bugreports: #88862

KDE fails to properly validate input when handling PCX images, potentially resulting in the execution of arbitrary code.

2. Impact Information

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

kimgio fails to properly validate input when handling PCX files.

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

3. Resolution Information

There is no known workaround at this time.

All kdelibs users should upgrade to the latest version:
