Astra Linux – Vulnerability in libgcrypt20

The ElGamal implementation in Libgcrypt before version 1.9.4 allows plaintext recovery. This occurs because, during interaction between two cryptographic libraries, a dangerous combination of elements arises—specifically, the prime number defined by the receiver’s public key, the generator define...

CVE-2026-41990

A flaw was found in Libgcrypt. During Dilithium signing operations, the library fails to perform a bounds check when writing to a static array. While the data involved is not directly controlled by an attacker, this vulnerability could lead to memory corruption, potentially resulting in a denial ...

CVE-2026-41989

A flaw was found in Libgcrypt. A remote attacker could exploit this vulnerability by sending crafted Elliptic Curve Diffie-Hellman ECDH ciphertext to the gcrypkdecrypt function. This can lead to a heap-based buffer overflow, potentially causing a denial of service DoS condition. Mitigation...
