Background

FreeType is a high-quality and portable font engine.

Description

A flaw in FreeType’s handling of embedded PNG bitmaps was discovered where the image height and width was not checked to be within bounds.

Impact

A remote attacker could entice a user to open a specially crafted font file using FreeType possibly resulting in the 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 FreeType users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=media-libs/freetype-2.10.3-r1"
