linux-pam: Plaintext password recovery via timing discrepancy in pam_userdb module

A flaw was found in Linux-PAM's pamuserdb module. This vulnerability, categorized as an Observable Timing Discrepancy CWE-208, allows a local or network-adjacent attacker to recover plaintext passwords. By repeatedly attempting authentication and measuring response-timing differences during...

RHEL 10 : pam (RHSA-2026:61229)

The remote Redhat Enterprise Linux 10 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2026:61229 advisory. Pluggable Authentication Modules PAM provide a system to set up authentication policies without the need to recompile programs to handle...

CVE-2026-81020

wolfEngine before 1.4.1 generates the 8-byte explicit AES-GCM nonce only once when the TLS write key is set and never increments it per record. Consequently, every TLS 1.2 and DTLS 1.2 AES-GCM record within a connection is encrypted under an identical key and nonce pair. GCM nonce reuse discloses...

CVE-2026-81530

MongoDB C# Driver has a weakness in its client-side encryption configuration where KMS key-management credentials supplied by the application are serialized verbatim into the driver's human-readable diagnostic settings representation instead of being masked like other secret fields. An attacker w...

CVE-2026-81530 KMS master key exposure via unredacted credential serialization in driver settings string

A weakness in the client-side encryption configuration surface of the MongoDB C Driver causes sensitive key-management credential material supplied by the application to be reproduced verbatim in the driver's human-readable diagnostic representation of its client settings, instead of being masked...

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...

Astra Linux – Vulnerability in OpenSSL

There exists a timing-based side channel in the OpenSSL RSA Decryption implementation. This vulnerability could be sufficient for an attacker to recover plaintext across a network in a Bleichenbacher-style attack. To successfully decrypt data, an attacker would need to be able to send a very larg...

Astra Linux – Vulnerability in mbedtls

A issue was discovered in Mbed TLS 2.x before 2.28.7, and in 3.x before 3.5.2. There was a timing-related side channel in RSA private operations. This side channel could allow a local attacker to recover the plaintext. It required the attacker to send a large number of messages for decryption, as...
