A vulnerability has been found and corrected in gif2png:

Stack-based buffer overflow in gif2png.c in gif2png 2.5.3 and earlier
might allow context-dependent attackers to execute arbitrary code
via a long command-line argument, as demonstrated by a CGI program
that launches gif2png (CVE-2009-5018).

Buffer overflow in gif2png.c in gif2png 2.5.3 and earlier might allow
context-dependent attackers to cause a denial of service (application
crash) or have unspecified other impact via a GIF file that contains
many images, leading to long extensions such as .p100 for PNG output
files, as demonstrated by a CGI program that launches gif2png,
a different vulnerability than CVE-2009-5018 (CVE-2010-4694).
