Vulnerable:

Yes

Security database references:

In the Bugtraq database (at SecurityFocus): BugTraq ID 6431.

More information:

Glenn Randers-Pehrson discovered a problem in connection with 16-bit samples from libpng, an interface for reading and writing PNG (Portable Network Graphics) format files. The starting offsets for the loops are calculated incorrectly which causes a buffer overrun beyond the beginning of the row buffer.

For the current stable distribution (woody) this problem has been fixed in version 1.0.12-3.woody.3 for libpng and in version 1.2.1-1.1.woody.3 for libpng3.

For the old stable distribution (potato) this problem has been fixed in version 1.0.5-1.1 for libpng. There are no other libpng packages.

For the unstable distribution (sid) this problem has been fixed in version 1.0.12-7 for libpng and in version 1.2.5-8 for libpng3.

We recommend that you upgrade your libpng packages.

Fixed in:

Debian GNU/Linux 2.2 (potato)
