TITLE

libpng of png_set_PLTE Buffer overflow vulnerability in functions

DESCRIPTION

Buffer overflow in the png_set_PLTE function in libpng before 1.0.65, 1.1.x and 1.2.x before 1.2.55, 1.3.x, 1.4.x before 1.4.18, 1.5.x before 1.5.25, and 1.6.x before 1.6.20 allows 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. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-8126. libpng of png_set_PLTE The function contains a buffer overflow vulnerability. libpng is prone to a heap-based buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied input. Attackers may leverage this issue to execute arbitrary code on the affected system. Failed attacks will cause denial-of-service conditions. Note: This issue is the result of an incomplete fix for the issue described in 77568 (libpng CVE-2015-8126 Multiple Heap Based Buffer Overflow Vulnerabilities). The following versions are affected: libpng prior to 1.0.65, 1.1.x and 1.2.x prior to 1.2.55, 1.3.x, 1.4.x prior to 1.4.18, 1.5.x prior to 1.5.25, 1.6 1.6.x versions prior to .20. 7) - x86_64 3. Description: IBM Java SE version 7 Release 1 includes the IBM Java Runtime Environment and the IBM Java Software Development Kit. This update fixes several vulnerabilities in the IBM Java Runtime Environment and the IBM Java Software Development Kit. Further information about these flaws can be found on the IBM Java Security alerts page, listed in the References section. (CVE-2015-5041, CVE-2015-7575, CVE-2015-7981, CVE-2015-8126, CVE-2015-8472, CVE-2015-8540, CVE-2016-0402, CVE-2016-0448, CVE-2016-0466, CVE-2016-0483, CVE-2016-0494) Note: This update also disallows the use of the MD5 hash algorithm in the certification path processing. The use of MD5 can be re-enabled by removing MD5 from the jdk.certpath.disabledAlgorithms security property defined in the java.security file. All running instances of IBM Java must be restarted for the update to take effect.

Summary: Updated libpng packages that fix three security issues are now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2.

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. 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.
