Описание

Libgcrypt before 1.12.2 sometimes allows a heap-based buffer overflow and denial of service via crafted ECDH ciphertext to gcry_pk_decrypt.

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

Меры по смягчению последствий

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
