Denial of Service (DoS)

Overview openssl-encrypt is an A package for secure file encryption and decryption based on modern ciphers using heavy-compute-load chaining of hashing and KDF to generate strong encryption password based on users provided password to ensure secure encryption of files Affected versions of this...

PYSEC-2026-3965

opensslencrypt before 1.4.9 fails to validate the memorycost parameter from identity file protection blocks, allowing attackers to trigger out-of-memory conditions during key derivation. Attackers with write access to local identity stores can craft malicious identity files with excessive...

CVE-2026-81720 openssl_encrypt before 1.4.9 Denial of Service via Unbounded Argon2

opensslencrypt before 1.4.9 fails to validate the memorycost parameter from identity file protection blocks, allowing attackers to trigger out-of-memory conditions during key derivation. Attackers with write access to local identity stores can craft malicious identity files with excessive...

CVE-2026-81720

openssl_encrypt before 1.4.9 fails to validate the memory_cost parameter found in identity file protection blocks. Because the value is passed unboundedly into Argon2 key derivation, an attacker with write access to local identity stores can craft a malicious identity file with an excessive memor...
