Detail

Several problems have been discovered in the FreeType 2 font engine. The Common vulnerabilities and Exposures project identifies the following problems:

CVE-2006-0747

Several integer underflows have been discovered which could allow remote attackers to cause a denial of service.

CVE-2006-1861

Chris Evans discovered several integer overflows that lead to a denial of service or could possibly even lead to the execution of arbitrary code.

CVE-2006-2493

Several more integer overflows have been discovered which could possibly lead to the execution of arbitrary code.

CVE-2006-2661

A null pointer dereference could cause a denial of service.

For the old stable distribution (woody) these problems have been fixed in version 2.0.9-1woody1.

For the stable distribution (sarge) these problems have been fixed in version 2.1.7-2.5.

For the unstable distribution (sid) these problems will be fixed soon

We recommend that you upgrade your libfreetype packages.
