Gentoo: GLSA-201006-02: CamlImages: User-assisted execution of arbitrary code
Summary
Tielei Wang reported multiple integer overflows, possibly leading to
heap-based buffer overflows in the (1) read_png_file() and
read_png_file_as_rgb24() functions, when processing a PNG image
(CVE-2009-2295) and (2) gifread.c and jpegread.c files when processing
GIF or JPEG images (CVE-2009-2660).
Other integer overflows were also found in tiffread.c (CVE-2009-3296).
Resolution
All CamlImages users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose =dev-ml/camlimages-3.0.2

Synopsis
Multiple integer overflows in CamlImages might result in the remote execution of arbitrary code.
Background
CamlImages is an image processing library for Objective Caml.
Affected Packages
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-ml/camlimages < 3.0.2 >= 3.0.2
Impact
===== A remote attacker could entice a user to open a specially crafted, overly large PNG, GIF, TIFF, or JPEG image using an application that uses the CamlImages library, possibly resulting in the execution of arbitrary code with the privileges of the user running the application.
Workaround
There is no known workaround at this time.
