Astra Linux – Vulnerability in nss

A flaw was discovered in the implementation of CHACHA20-POLY1305 in NSS versions prior to 3.55. When using multi-part Chacha20, it could lead to out-of-bounds reads. This issue was addressed by explicitly disabling multi-part ChaCha20 which was not functioning correctly and enforcing strict tag...

Astra Linux – Vulnerabilities in paramiko, libssh, libssh2, erlang, openssh

The SSH transport protocol, with certain OpenSSH extensions, found in OpenSSH versions prior to 9.6 and other products, allows remote attackers to bypass integrity checks. As a result, some packets may be omitted from the extension negotiation message. Consequently, the client and server may end ...

openssl: openssl: AEAD forgeries possible with empty ciphertext in EVP_Cipher()

A flaw in OpenSSL causes EVPCipher to skip AEAD tag verification for ChaCha20-Poly1305 and AES-OCB ciphers when decrypting empty ciphertexts. This allows remote attackers to submit forged messages that affected applications incorrectly accept as valid...
