Date:	03/15/2020
Bugs:	#699830
ID:	202003-23

Synopsis

Several integer overflows in libjpeg-turbo might allow an attacker to execute arbitrary code.

Background

libjpeg-turbo is a MMX, SSE, and SSE2 SIMD accelerated JPEG library.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
media-libs/libjpeg-turbo	< 2.0.3	>= 2.0.3	All supported architectures

Description

It was discovered that libjpeg-turbo incorrectly handled certain JPEG images.

Impact

A remote attacker could entice a user to open a specially crafted JPEG file in an application linked against libjpeg-turbo, 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 libjpeg-turbo users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=media-libs/libjpeg-turbo-2.0.3"
