Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 533676, Bug 572308.
In Mitre's CVE dictionary: CVE-2009-2042, CVE-2010-0205.

More information:

Several vulnerabilities have been discovered in libpng, a library for reading and writing PNG files. The Common Vulnerabilities and Exposures project identifies the following problems:

• CVE-2009-2042

  libpng does not properly parse 1-bit interlaced images with width values that are not divisible by 8, which causes libpng to include uninitialized bits in certain rows of a PNG file and might allow remote attackers to read portions of sensitive memory via "out-of-bounds pixels" in the file.

• CVE-2010-0205

  libpng does not properly handle compressed ancillary-chunk data that has a disproportionately large uncompressed representation, which allows remote attackers to cause a denial of service (memory and CPU consumption, and application hang) via a crafted PNG file

For the stable distribution (lenny), these problems have been fixed in version 1.2.27-2+lenny3.

For the testing (squeeze) and unstable (sid) distribution, these problems have been fixed in version 1.2.43-1

We recommend that you upgrade your libpng package.

Fixed in:

Debian GNU/Linux 5.0 (lenny)
