Debian 5.0 Lenny DSA-2116-1 Critical: Freetype Integer Overflow

debian
Calendar Grey October 4, 2010
Debian Logo
Enhance the freetype libraries to address an integer overrun vulnerability in FreeType's font processing, which may lead to unexpected application failures.
Marc Schoenefeld has found an input stream position error in the way the FreeType font rendering engine processed input file streams

Summary

After the upgrade, all running applications and services that use
libfreetype6 should be restarted. In most cases, logging out and
in again should be enough. The script checkrestart from the
debian-goodies package or lsof may help to find out which
processes are still using the old version of libfreetype6.

For the stable distribution (lenny), these problems have been fixed in
version 2.3.7-2+lenny4.

The testing distribution (squeeze) and the unstable distribution (sid)
are not affected by this problem.

We recommend that you upgrade your freetype packages.
