1. Systems affected:

    kdelibs as shipped with KDE 3.2 up to including KDE 3.4.
   

2. Overview:

    kimgio contains a PCX image file format reader that does
    not properly perform input validation. A source code audit
    performed by the KDE security team discovered several
    vulnerabilities in the PCX and other image file format
    readers, some of them exploitable to execute arbitrary
    code.
   

3. Impact:

    Remotly supplied, specially crafted image files can be used
    to execute arbitrary code.
   

4. Solution:

    Source code patches have been made available which fix these
    vulnerabilities. Contact your OS vendor / binary package provider
    for information about how to obtain updated binary packages.

    A patch for KDE 3.4.0 is available from
