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.
