[GLSA]

Gentoo Linux Security Advisory

Title: CamlImages: User-assisted execution of arbitrary code (GLSA 201006-02)
Severity: normal
Exploitable: remote
Date: June 01, 2010
Bug(s): #276235, #290222
ID: 201006-02

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: dev-ml/camlimages
Vulnerable: < 3.0.2
Unaffected: >= 3.0.2
Architectures: All supported architectures


Description


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).


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.


Resolution


All CamlImages users should upgrade to the latest version:
