Short explanation
A flaw exists in the libstdc++ component of GCC where providing an excessively large element count to a boolean vector constructor can trigger an integer wrap during internal memory calculations, leading to out-of-bounds memory access and Denial of Service.
This vulnerability allows attackers to disrupt container consistency, resulting in application crashes or Denial of Service conditions during subsequent operations.
What should be done?
- Follow vendor advisories
- Apply available updates
Chain of evidence and sources
GCC libstdc++ bileşenindeki zafiyet, boolean vektör yapıcısına aşırı büyük eleman sayısı verildiğinde tam sayı kaymasına yol açar.
Bu durum kapsayıcının tutarsız bir duruma gelmesine ve bellek sınırları dışı erişim ile Hizmet Engellemeye neden olur.
Show the technical text from the sources
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 container in an inconsistent state, leading to out-of-bounds memory access and resulting in an application crash or a Denial of Service (DoS) during subsequent operations.
