maxminddb's `Reader::open_mmap` unsoundly marks unsafe memmap operation as safe

maxminddb prior to version 0.27 declared Reader::openmmap as safe despite wrapping an inherently unsafe memmap2 operation with no extra step done to guarantee safety. This could have led to undefined behaviour if the file were to be modified on disk while the memory map was still active...

JLSEC-2025-332 A flaw was found in libssh when using the ChaCha20 cipher with the OpenSSL library

A flaw was found in libssh when using the ChaCha20 cipher with the OpenSSL library. If an attacker manages to exhaust the heap space, this error is not detected and may lead to libssh using a partially initialized cipher context. This occurs because the OpenSSL error code returned aliases with th...
