Detail

Synopsis

Multiple vulnerabilities have been found in gif2png, the worst of which might allow execution of arbitrary code.

Background

gif2png converts images from GIF format to PNG format.

Description

Two vulnerabilities have been found in gif2png:

* A boundary error in gif2png.c could cause a buffer overflow (CVE-2010-4694).
* The patch for CVE-2009-5018 causes gif2png to truncate GIF pathnames (CVE-2010-4695).

Impact

A remote attacker could entice a user to open a specially crafted GIF file, possibly resulting in execution of arbitrary code, a Denial of Service condition, or the creation of PNG files in unintended directories.

Workaround

There is no known workaround at this time.

Resolution

All gif2png users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/gif2png-2.5.8"

Open Source Vulnerability Database (OSVDB)

Id Description
70481 gif2png gif2png.c GIF Pathname Truncation Arbitrary PNG File Creation

gif2png contains a flaw related to the Fedora patch for gif2pnc.c's truncating a GIF pathname specified on the command line. This may allow a remote attacker to create PNG files in unintended directories via a crafted command-line argument.
70480 gif2png gif2png.c Multiple Image GIF File Handling Overflow DoS

gif2png is prone to an overflow condition. The 'gif2png.c' function fails to properly sanitize user-supplied input resulting in a buffer overflow. With a specially crafted GIF file, a context-dependent attacker can potentially execute arbitrary code.
