The Common Vulnerabilities and Exposures project identifies the following problems:

CVE-2007-2645

Victor Stinner discovered an integer overflow, which may result in denial of service or potentially the execution of arbitrary code.

CVE-2007-6351

Meder Kydyraliev discovered an infinite loop, which may result in denial of service.

CVE-2007-6352

Victor Stinner discovered an integer overflow, which may result in denial of service or potentially the execution of arbitrary code.

This update also fixes two potential NULL pointer deferences.

For the old stable distribution (sarge), these problems have been fixed in 0.6.9-6sarge2.

For the stable distribution (etch), these problems have been fixed in version 0.6.13-5etch2.

We recommend that you upgrade your libexif packages.");
