CVE-2007-0455

Kees Cook discovered a buffer overflow in libgd2's font renderer. An attacker could cause denial of service (application crash) and possibly execute arbitrary code via a crafted string with a JIS encoded font. This issue only affects the oldstable distribution (etch).

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 (etch), these problems have been fixed in version 2.0.33-5.2etch2.

For the stable distribution (lenny), these problems have been fixed in version 2.0.36~rc1~dfsg-3+lenny1.

For the upcoming stable distribution (squeeze) and the unstable distribution (sid), these problems have been fixed in version 2.0.36~rc1~dfsg-3.1.

We recommend that you upgrade your libgd2 packages.");
