USN-218-1: netpbm vulnerabilities

Publication date

22 November 2005

Overview

netpbm vulnerabilities

Releases

Details

Two buffer overflows were discovered in the ‘pnmtopng’ tool, which
were triggered by processing an image with exactly 256 colors when
using the -alpha option (CVE-2005-3662) or by processing a text file
with very long lines when using the -text option (CVE-2005-3632).

A remote attacker could exploit these to execute arbitrary code by
tricking an user or an automated system into processing a specially
crafted PNM file with pnmtopng.
