Synopsis ========
An integer underflow vulnerability in Pixman may allow a context-dependent attacker to cause Denial of Service.
Background ==========
Pixman is a pixel manipulation library.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 x11-libs/pixman < 0.32.4 >= 0.32.4
Description ===========
The trapezoid handling code in Pixman contains an integer underflow vulnerability.
Impact ======
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.
Workaround ==========
There is no known workaround at this time.
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.
