high Nessus Plugin ID 30226

Synopsis

The remote Debian host is missing a security-related update.

Description

Several vulnerabilities have been discovered in the EXIF parsing code of the libexif library, which can lead to denial of service or the execution of arbitrary code if a user is tricked into opening a malformed image. 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.

Solution

Upgrade the libexif packages.

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.
