CVE-2016-3705

TITLE

libxml2 of parser.c of xmlParserEntityCheck and xmlParseAttValueComplex Service disruption in functions (DoS) Vulnerabilities

DESCRIPTION

The (1) xmlParserEntityCheck and (2) xmlParseAttValueComplex functions in parser.c in libxml2 2.9.3 do not properly keep track of the recursion depth, which allows context-dependent attackers to cause a denial of service (stack consumption and application crash) via a crafted XML document containing a large number of nested entity references. libxml2 is prone to a stack-based buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied input. Attackers can exploit this issue to execute arbitrary code in the context of the affected application. Failed exploit attempts will likely cause a denial-of-service condition. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: libxml2 security update Advisory ID: RHSA-2016:1292-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2016:1292 Issue date: 2016-06-23 CVE Names: CVE-2016-1762 CVE-2016-1833 CVE-2016-1834 CVE-2016-1835 CVE-2016-1836 CVE-2016-1837 CVE-2016-1838 CVE-2016-1839 CVE-2016-1840 CVE-2016-3627 CVE-2016-3705 CVE-2016-4447 CVE-2016-4448 CVE-2016-4449 ===================================================================== 1. Summary: An update for libxml2 is now available for Red Hat Enterprise Linux 6 and Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2.

Description: The libxml2 library is a development toolbox providing the implementation of various XML standards. Security Fix(es): A heap-based buffer overflow flaw was found in the way libxml2 parsed certain crafted XML input. A remote attacker could provide a specially crafted XML file that, when opened in an application linked against libxml2, would cause the application to crash or execute arbitrary code with the permissions of the user running the application. (CVE-2016-1834, CVE-2016-1840) Multiple denial of service flaws were found in libxml2. A remote attacker could provide a specially crafted XML file that, when processed by an application using libxml2, could cause that application to crash. (CVE-2016-1762, CVE-2016-1833, CVE-2016-1835, CVE-2016-1836, CVE-2016-1837, CVE-2016-1838, CVE-2016-1839, CVE-2016-3627, CVE-2016-3705, CVE-2016-4447, CVE-2016-4448, CVE-2016-4449) 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 For the update to take effect, all applications linked to the libxml2 library must be restarted, or the system rebooted. 5.
