All supported architectures
An integer underflow vulnerability in Pixman may allow a
context-dependent attacker to cause Denial of Service.
Pixman is a pixel manipulation library.
The trapezoid handling code in Pixman contains an integer underflow
A context-dependent attacker could entice a user to open a specially
crafted file using an application linked against Pixman, 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 Pixman users should upgrade to the latest version:
Code Listing 3.1: Resolution
# emerge --sync
# emerge --ask --oneshot --verbose ">=x11-libs/pixman-0.32.4"
Packages which depend on this library may need to be recompiled. Tools
such as revdep-rebuild may assist in identifying these packages.
