a4bd3039-9a48-11d9-a256-0001020eed82xv -- filename handling format string vulnerability

A Gentoo Linux Security Advisory reports:

Tavis Ormandy of the Gentoo Linux Security Audit Team identified a flaw in the handling of image filenames by xv.

Successful exploitation would require a victim to process a specially crafted image with a malformed filename, potentially resulting in the execution of arbitrary code.

fffacc93-16cb-11d9-bc4a-000c41e2cdadxv -- exploitable buffer overflows

In a Bugtraq posting, infamous41md(at) reported:

there are at least 5 exploitable buffer and heap overflows in the image handling code. this allows someone to craft a malicious image, trick a user into viewing the file in xv, and upon viewing that image execute arbitrary code under privileges of the user viewing image. note the AT LEAST part of the above sentence. there is such a plethora of bad code that I just stopped reading after a while. there are at least 100 calls to sprintf() and strcpy() with no regards for bounds of buffers. 95% of these deal with program arguments or filenames, so they are of no interest to exploit. however I just got sick of reading this code after not too long. so im sure there are still other overflows in the image handling code for other image types.

The posting also included an exploit.
