1. Problem Description
Tavis Ormandy has reported a vulnerability in libTIFF, which
potentially can be exploited by malicious people to compromise
a vulnerable system.
The vulnerability is caused due to a boundary error and can
be exploited to cause a buffer overflow via a specially crafted
TIFF image containing a malformed BitsPerSample tag.
Successful exploitation may allow execution of arbitrary code,
if a malicious TIFF image is opened in an application linked
against the vulnerable library.
The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the following name CAN-2005-1544 to this issue.
