Detail

Synopsis

A buffer overflow in Pixman might allow remote attackers to execute arbitrary code.

Background

Pixman is a pixel manipulation library.

Description

In pixman-general, careless computations done with the 'dest_buffer'
pointer may overflow, failing the buffer upper limit check.

Impact

A remote attacker could possibly cause a Denial of Service condition, or execute arbitrary code with the privileges of the process.

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-0.32.8"
