kdelibs -- kimgio input validation errors

A KDE Security Advisory reports:

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.
Impact: Remotely supplied, specially
crafted image files can be used to execute arbitrary
code.
