Title:	LittleCMS: User-assisted execution of arbitrary code
Date:	05/26/2021
Bugs:	#761418
ID:	202105-18

Synopsis

A heap-based buffer overflow in LittleCMS might allow remote attackers to execute arbitrary code.

Background

LittleCMS, or short lcms, is a color management system for working with ICC profiles. It is used by many applications including GIMP, Firefox and Chromium.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
media-libs/lcms	< 2.10	>= 2.10	All supported architectures

Description

It was discovered that LittleCMS (aka Little Color Management System) had an integer overflow in the AllocateDataSet function in cmscgats.c.

Impact

A remote attacker could entice a user or automated system to open a specially crafted file containing malicious color data, 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 LittleCMS users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=media-libs/lcms-2.10"
