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-2010-1205

  It was discovered a buffer overflow in libpng which allows remote attackers to execute arbitrary code via a PNG image that triggers an additional data row.

• CVE-2010-2249

  It was discovered a memory leak in libpng which allows remote attackers to cause a denial of service (memory consumption and application crash) via a PNG image containing malformed Physical Scale (aka sCAL) chunks.

For the stable distribution (lenny), these problems have been fixed in version 1.2.27-2+lenny4.

For the testing (squeeze) and unstable (sid) distribution, these problems have been fixed in version 1.2.44-1.

We recommend that you upgrade your libpng package.

Fixed in:

Debian GNU/Linux 5.0 (lenny)
