GEGL is a graph-based image processing framework.
Multiple integer overflows in GEGL may cause a heap-based buffer overflow.
A remote attacker could entice a user to open a specially crafted PPM image using an application linked against GEGL, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.
There is no known workaround at this time.
All gegl users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/gegl-0.2.0-r2"
Packages which depend on this library may need to be recompiled. Tools such as revdep-rebuild may assist in identifying some of these packages.
