Description
A vulnerability in the libstdc++ component of GCC allows an attacker to trigger an integer wrap by providing an excessively large element count to a std::vector<bool> constructor. This leads to an inconsistent container state and out-of-bounds memory access, causing application crashes or Denial of Service (DoS). Exploitation requires attacker-controlled near-maximum integer values during container initialization, limiting the practical exposure. No mitigation is currently available that meets Red Hat's criteria, and the vulnerability is rated moderate severity.
