A flaw was found in GCC. An out-of-bounds memory access vulnerability exists in the libstdc++ parallel search implementation due to an undersized internal buffer. A local attacker can exploit this flaw by providing crafted search data to an application compiled with parallel mode, causing the process to crash and leading to a Denial of Service (DoS).
