Gentoo: GLSA-201206-20: gdk-pixbuf: Denial of Service
Summary
Two vulnerabilities have been found in gdk-pixbuf:
* The "gdk_pixbuf__gif_image_load()" function in io-gif.c fails to
properly handle certain return values from subroutines
(CVE-2011-2485).
* The "read_bitmap_file_data()" function in io-xbm.c contains an
integer overflow error (CVE-2012-2370).
Resolution
All gdk-pixbuf users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=x11-libs/gdk-pixbuf-2.24.1-r1"
Packages which depend on this library may need to be recompiled. Tools
such as revdep-rebuild may assist in identifying some of these
packages.
