CVE-2011-1944

Status Candidate

Overview

Integer overflow in xpath.c in libxml2 2.6.x through 2.6.32 and 2.7.x through 2.7.8, and libxml 1.8.16 and earlier, allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted XML file that triggers a heap-based buffer overflow when adding a new namespace node, related to handling of XPath expressions.

Apple Security Advisory 2012-05-09-1 - OS X Lion v10.7.4 and Security Update 2012-002 is now available and addresses multiple security issues. An issue existed in the handling of network account logins. The login process recorded sensitive information in the system log, where other users of the system could read it. A temporary file race condition issue existed in blued's initialization routine. There are known attacks on the confidentiality of SSL 3.0 and TLS 1.0 when a cipher suite uses a block cipher in CBC mode. curl disabled the 'empty fragment' countermeasure which prevented these attacks. This issue is addressed by enabling empty fragments. A data injection issue existed in curl's handling of URLs. This issue is addressed through improved validation of URLs. This issue does not affect systems prior to OS X Lion. Various other vulnerabilities have been addressed.

Red Hat Security Advisory 2012-0017-01 - The libxml2 library is a development toolbox providing the implementation of various XML standards. One of those standards is the XML Path Language, which is a language for addressing parts of an XML document. A heap-based buffer overflow flaw was found in the way libxml2 decoded entity references with long names. 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, potentially, execute arbitrary code with the privileges of the user running the application.

One of those standards is the XML Path Language, which is a language for addressing parts of an XML document. An off-by-one error, leading to a heap-based buffer overflow, was found in the way libxml2 parsed certain XML files.

Mandriva Linux Security Advisory 2011-131 - Multiple vulnerabilities has been discovered and corrected in libxml/libxml2. Integer overflow in xpath.c in libxml2 2.6.x through 2.6.32 and 2.7.x through 2.7.8, and libxml 1.8.16 and earlier, allows context-dependent attackers to cause a denial of service and possibly execute arbitrary code via a crafted XML file that triggers a heap-based buffer overflow when adding a new namespace node, related to handling of XPath expressions. The updated packages have been patched to correct this issue. Packages were missing for Mandriva Linux 2011 with the MDVSA-2011:131 advisory which are now being provided.
