Tavis Ormandy discovered that the Tag Image File Format (TIFF) library is vulnerable to a buffer overflow triggered by a crafted OJPEG file which allows for a crash and potentially execution of arbitrary code.

The oldstable distribution (lenny) is not affected by this problem.

For the stable distribution (squeeze), this problem has been fixed in version 3.9.4-5+squeeze2.

For the testing distribution (wheezy) and unstable distribution (sid), this problem has been fixed in version 3.9.5-1.

We recommend that you upgrade your tiff packages.
