| Description: | Several vulnerabilities have been discovered in libgd2, a library for programmatic graphics creation and manipulation. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2007-0455 Kees Cook discovered a buffer overflow in libgd2's font renderer. An attacker could cause denial of service and possibly execute arbitrary code via a crafted string with a JIS encoded font. This issue only affects the oldstable distribution. CVE-2009-3546 Tomas Hoger discovered a boundary error in the "_gdGetColors" function. An attacker could conduct a buffer overflow or buffer over-read attacks via a crafted GD file. For the oldstable distribution, these problems have been fixed in version 2.0.33-5.2etch2. For the stable distribution, these problems have been fixed in version 2.0.36~rc1~dfsg-3+lenny1. For the upcoming stable distribution and the unstable distribution ion, these problems have been fixed in version 2.0.36~rc1~dfsg-3.1. We recommend that you upgrade your libgd2 packages. |
