Gentoo GLSA 202105-18 High: LittleCMS Remote Attack Risk

A heap-based buffer overflow in LittleCMS might allow remote attackers to execute arbitrary code.. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 202105-18 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - https://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: Normal Title: LittleCMS: User-assisted execution of arbitrary code Date: May 26, 2021 Bugs: #761418 ID: 202105-18 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======= A heap-based buffer overflow in LittleCMS might allow remote attackersto 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 ------------------------------------------------------------------- 1 media-libs/lcms < 2.10 > = 2.10 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" References ========= [ 1 ] CVE-2018-16435 https://nvd.nist.gov/vuln/detail/CVE-2018-16435 Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/202105-18 Concerns? ======== Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users' machines is of utmost importance to us.

Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/lcms < 2.6-r1 > = 2.6-r1 Description ========== Multiple stack-based buffer overflows and a profile parser error have been found in LittleCMS. Impact ===== A remote attacker could entice a user or automated system to open a specially crafted file containing a malicious ICC profile, possibly resulting in 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-2.6-r1" Packages which depend on this library may need to be recompiled. Tools such as revdep-rebuild may assist in identifying these packages. NOTE: Gentoo has discontinued support for the LittleCMS 1.9 branch.
