a vulnerability that causes it to write a file in $TMPDIR with
almost infinite size, which can severly impact system performance.

3. Impact:
Remotely supplied pdf files can be used to fill up all available
disk space when opened with kpdf.

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.
