Description Jan Lieskovsky 2013-06-06 14:53:46 UTC
A heap-based buffer overflow flaw was found in the way Exclusive Canonicalization PrefixList attribute content processing functionality of Apache Santuario-C++ (AKA xml-security-c), a C++ language implementation of W3C security standards for XML, used to manage internal buffers in certain circumstances. A remote attacker could provide a XML file with specially-crafted value of the PrefixList attribute to an application linked against xml-security-c performing Exclusive Canonicalization-based XML verification that, when processed would lead to that application crash or, potentially, arbitrary code execution with the privileges of the user running the application.
