CVE-2013-2210

Status Candidate

Overview

Heap-based buffer overflow in the XML Signature Reference functionality in Apache Santuario XML Security for C++ (aka xml-security-c) before 1.7.2 allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via malformed XPointer expressions. NOTE: this is due to an incorrect fix for CVE-2013-2154.

Debian Linux Security Advisory 2717-1 - Jon Erickson of iSIGHT Partners Labs discovered a heap overflow in xml-security-c, an implementation of the XML Digital Security specification. The fix to address CVE-2013-2154 introduced the possibility of a heap overflow in the processing of malformed XPointer expressions in the XML Signature Reference processing code, possibly leading to arbitrary code execution.

Apache Santuario XML Security For C++ Heap Overflow
Posted Jun 27, 2013
Authored by Jon Erickson

The attempted fix to address CVE-2013-2154 introduced the possibility of a heap overflow, possibly leading to arbitrary code execution, in the processing of malformed XPointer expressions in the XML Signature Reference processing code. An attacker could use this to exploit an application performing signature verification if the application does not block the evaluation of such references prior to performing the verification step. The exploit would occur prior to the actual verification of the signature, so does not require authenticated content. Apache Santuario XML Security for C++ library versions prior to 1.7.2 are affected.
