Details

Tavis Ormandy discovered a buffer overflow in the TIFF library. A
malicious image with an invalid “bits per sample” number could be
constructed which, when decoded, would have resulted in execution of
arbitrary code with the privileges of the process using the library.

Since this library is used in many applications like “ghostscript” and
the “CUPS” printing system, this vulnerability may lead to remotely
induced privilege escalation.
