TITLE

libpng Buffer error vulnerability

DESCRIPTION

Multiple buffer overflows in the (1) png_set_PLTE and (2) png_get_PLTE functions in libpng before 1.0.64, 1.1.x and 1.2.x before 1.2.54, 1.3.x and 1.4.x before 1.4.17, 1.5.x before 1.5.24, and 1.6.x before 1.6.19 allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a small bit-depth value in an IHDR (aka image header) chunk in a PNG image. libpng is prone to multiple heap-based buffer-overflow vulnerabilities because it fails to perform adequate boundary checks on user-supplied input. Attackers may leverage these issues to execute arbitrary code on the affected system. Failed attacks will cause denial-of-service conditions. Background ========== Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web. ============================================================================ Ubuntu Security Notice USN-2815-1 November 19, 2015 libpng vulnerabilities ============================================================================ A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 15.10 - Ubuntu 15.04 - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS Summary: libpng could be made to crash or run programs as your login if it opened a specially crafted file. This issue only affected Ubuntu 12.04 LTS. (CVE-2012-3425) Qixue Xiao discovered that libpng incorrectly handled certain time values. (CVE-2015-7981) It was discovered that libpng incorrectly handled certain small bit-depth values. (CVE-2015-8126) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 15.10: libpng12-0 1.2.51-0ubuntu3.15.10.1 Ubuntu 15.04: libpng12-0 1.2.51-0ubuntu3.15.04.1 Ubuntu 14.04 LTS: libpng12-0 1.2.50-1ubuntu2.14.04.1 Ubuntu 12.04 LTS: libpng12-0 1.2.46-3ubuntu4.1 After a standard system update you need to restart your session to make all the necessary changes. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 201611-08 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - https://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: Normal Title: libpng: Multiple vulnerabilities Date: November 15, 2016 Bugs: #564244, #565678, #568216 ID: 201611-08 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======== Multiple vulnerabilities have been found in libpng, the worst of which may allow remote attackers to cause Denial of Service.

Description: The libpng packages contain a library of functions for creating and manipulating PNG (Portable Network Graphics) image format files. It was discovered that the png_get_PLTE() and png_set_PLTE() functions of libpng did not correctly calculate the maximum palette sizes for bit depths of less than 8. In case an application tried to use these functions in combination with properly calculated palette sizes, this could lead to a buffer overflow or out-of-bounds reads. An attacker could exploit this to cause a crash or potentially execute arbitrary code by tricking an unsuspecting user into processing a specially crafted PNG image. However, the exact impact is dependent on the application using the library. (CVE-2015-8126, CVE-2015-8472) An array-indexing error was discovered in the png_convert_to_rfc1123() function of libpng. An attacker could possibly use this flaw to cause an out-of-bounds read by tricking an unsuspecting user into processing a specially crafted PNG image. (CVE-2015-7981) All libpng users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied.
