Red Hat Security Advisory 2013-1411-01 – The glibc packages provide the standard C libraries, POSIX thread libraries, standard math libraries, and the Name Server Caching Daemon used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly. Multiple integer overflow flaws, leading to heap-based buffer overflows, were found in glibc’s memory allocator functions. If an application used such a function, it could cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application….
