Переполнение буфера было обнаружено в динамическом загрузчике ld.so библиотеки GNU C при обработке переменной среды GLIBC_TUNABLES. Эта проблема может позволить локальному злоумышленнику использовать злонамеренно созданные переменные среды GLIBC_TUNABLES при запуске двоичных файлов с разрешением SUID для выполнения кода с повышенными привилегиями.
Показать оригинальное описание (EN)
A buffer overflow was discovered in the GNU C Library's dynamic loader ld.so while processing the GLIBC_TUNABLES environment variable. This issue could allow a local attacker to use maliciously crafted GLIBC_TUNABLES environment variables when launching binaries with SUID permission to execute code with elevated privileges.
