An integer underflow vulnerability in Pixman may allow a context-dependent attacker to cause Denial of Service.
|Package||x11-libs/pixman on all architectures|
|Affected versions||< 0.32.4|
|Unaffected versions||>= 0.32.4|
Pixman is a pixel manipulation library.
The trapezoid handling code in Pixman contains an integer underflow vulnerability.
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:
# 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.
