Synopsis
Multiple vulnerabilities in gdk-pixbuf may create a Denial of Service condition.Background
gdk-pixbuf is an image loading library for GTK+.
Affected packages
Package | Vulnerable | Unaffected | Architecture(s) |
---|---|---|---|
x11-libs/gdk-pixbuf | < 2.24.1-r1 | >= 2.24.1-r1 | All supported architectures |
Description
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).
Impact
A remote attacker could entice a user to open a specially crafted image in an application linked against gdk-pixbuf, possibly resulting in Denial of Service.
Workaround
There is no known workaround at this time.
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.
