CVE-2013-0252

boost :: locale :: utf :: utf_traits en la biblioteca Boost Boost.Locale en Boost v1.48 hasta v1.52 no detecta correctamente ciertas secuencias UTF-8 inválidaso, lo que podría permitir a atacantes remotos eludir el mecanismo de protección mediante la manipulación de determinados bytes.

A security flaw was found in the way ordered_malloc() routine implementation in Boost, the free peer-reviewed portable C++ source libraries, performed 'next-size' and 'max_size' parameters sanitization, when allocating memory. If an application, using the Boost C++ source libraries for memory allocation, was missing application-level checks for safety of 'next_size' and 'max_size' values, a remote attacker could provide a specially-crafted application-specific file (requiring runtime memory allocation it to be processed correctly) that, when opened would lead to that application crash, or, potentially arbitrary code execution with the privileges of the user running the application. Boost.Locale library in Boost 1.48 to 1.52 including has a security flaw. ): boost::locale::utf::utf_traits accepted some invalid UTF-8 sequences. Applications that used these functions for UTF-8 input validation could expose themselves to security threats as invalid UTF-8 sequence would be considered as valid. The package has been patched to fix above security flaw.
