Gcc: confirmed out-of-bounds read/write in libstdc++ parallel `std
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 compil…

Gcc: integer wrap in `std
A flaw was found in the libstdc++ component of GCC. An attacker who can provide an excessively large element count to a boolean vector (std::vector<bool>) constructor can trigger an integer wrap during internal memory calculations. This issue leaves the conta…
