http://security.gentoo.org/

Severity:	normal
Title:	FreeType: Arbitrary code execution
Date:	10/23/2020
Bugs:	#750275
ID:	202010-07

Synopsis

A buffer overflow in FreeType might allow remote attacker(s) to execute arbitrary code.

Background

FreeType is a high-quality and portable font engine.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
media-libs/freetype	< 2.10.3-r1	>= 2.10.3-r1	All supported architectures

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"
