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.
Solution:
A fix is reportedly available in the CVS repository.
Provided and/or discovered by:
Tavis Ormandy, Gentoo Linux Security Audit Team.
