xfree86 - integer overflow

Søren Sandmann discovered a bug in memory allocation for pixmap images,
that can cause a crash of the X server or to execute arbitrary code.

The update for the old stable distribution (woody) also contains a
different correction for multiple vulnerabilities in libXpm (DSA 607, CAN-2004-0914,
Bug#309143),
since the old fix contained a regression.

For the old stable distribution (woody) this problem has been fixed in
version 4.1.0-16woody7.

For the stable distribution (sarge) this problem has been fixed in
version 4.3.0.dfsg.1-14sarge1.

For the unstable distribution (sid) this problem has been fixed in
version 6.8.2.dfsg.1-7 of X.Org.

We recommend that you upgrade your xfree86 and xorg packages.
