GLSA-201006-02 : CamlImages: User-assisted execution of arbitrary code
High Nessus Plugin ID 46769
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-201006-02 (CamlImages: User-assisted execution of arbitrary code)
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).
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.
There is no known workaround at this time.
SolutionAll CamlImages users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose =dev-ml/camlimages-3.0.2
