SUSE SLES12 Security Update : compat-openssl098 (SUSE-SU-2023:0581-1)
The remote SUSE Linux SLES12 / SLESSAP12 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2023:0581-1 advisory. - CVE-2022-4304: Fixed timing Oracle in RSA Decryption bsc1207534. Tenable has extracted the preceding description block directly from the...
openssl: timing attack in RSA Decryption implementation
A timing-based side channel exists in the OpenSSL RSA Decryption implementation, which could be sufficient to recover a ciphertext across a network in a Bleichenbacher style attack. To achieve a successful decryption, an attacker would have to be able to send a very large number of trial messages...
Ubuntu 20.04 LTS / 22.04 LTS : GnuTLS vulnerability (USN-5901-1)
The remote Ubuntu 20.04 LTS / 22.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-5901-1 advisory. Hubert Kario discovered that GnuTLS had a timing side-channel when handling certain RSA messages. A remote attacker could possibly use this issue to...

K10281096: TLS in Mozilla NSS vulnerability CVE-2018-12404
Security Advisory Description A cached side channel attack during handshakes using RSA encryption could allow for the decryption of encrypted content. This is a variant of the Adaptive Chosen Ciphertext attack AKA Bleichenbacher attack and affects all NSS versions prior to NSS 3.41. CVE-2018-1240...
K97324400: OpenSSL vulnerability CVE-2019-1563
Security Advisory Description In situations where an attacker receives automated notification of the success or failure of a decryption attempt an attacker, after sending a very large number of messages to be decrypted, can recover a CMS/PKCS7 transported encryption key or decrypt any RSA encrypt...
K54039800: MatrixSSL vulnerability CVE-2016-6883
Security Advisory Description MatrixSSL before 3.8.3 configured with RSA Cipher Suites allows remote attackers to obtain sensitive information via a Bleichenbacher variant attack. CVE-2016-6883 Impact There is no impact; F5 products are not affected by this vulnerability. Security Advisory Status...
OESA-2023-1107 openssl security update
Security Fixes: The public API function BIOnewNDEF is a helper function used for streaming ASN.1 data via a BIO. It is primarily used internally to OpenSSL to support the SMIME, CMS and PKCS7 streaming capabilities, but may also be called directly by end user applications. The function receives a...
