Gentoo: GLSA-201402-03: Pixman: User-assisted execution of arbitrary code
Summary
The trapezoid handling code in Pixman contains an integer underflow vulnerability.
Resolution
All Pixman users should upgrade to the latest version:
# 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.
