CVE-2012-3405
First published: Wed Jun 20 2012(Updated: )
It was discovered that the formatted printing functionality in glibc used extend_alloca() incorrectly. A remote attacker could provide a specially crafted sequence of format specifiers, leading to a desynchronization within the buffer size handling, resulting in the use of uninitialized memory or, potentially, FORTIFY_SOURCE format string protection mechanism bypass, when processed.
