Timing-channel attack in PostgreSQL MD5 password authentication enables remote unauthenticated attackers to extract user credentials through statistical analysis of authentication response times, affecting versions prior to 18.4, 17.10, 16.14, 15.18, and 14.23. The vulnerability exploits variable-time comparison operations during MD5 password hash verification, but does not impact the default scram-sha-256 authentication method. Databases migrated from PostgreSQL 13 or earlier may retain MD5-hashed passwords and remain vulnerable despite running newer versions.
Non-constant time comparison operations in the Legion of the Bouncy Castle BC-JAVA cryptographic library (core modules, versions 2.17.3 through 1.83) expose FrodoKEM private keys to timing side-channel attacks, enabling remote unauthenticated attackers to extract cryptographic secrets through statistical analysis of operation timing variations. CVSS 4.0 score of 10.0 reflects maximum confidentiality and integrity impact across system and subsequent contexts. EPSS probability is low (0.04%, 14th percentile) and no active exploitation is confirmed, but SSVC framework rates this as automatable with total technical impact. Vendor patch available in BC-JAVA 1.84.
A side-channel vulnerability exists in the implementation of BIP-39 mnemonic processing, as observed in Trezor One v1.13.0 to v1.14.0, Trezor T v1.13.0 to v1.14.0, and Trezor Safe v1.13.0 to v1.14.0 hardware wallets. This originates from the BIP-39 standard guidelines, which induce non-constant time execution and specific branch patterns for word searching. An attacker with physical access during the initial setup phase can collect a single side-channel trace. By utilizing profiling-based Deep Learning Side-Channel Analysis (DL-SCA), the attacker can recover the mnemonic code and subsequently steal the assets. The issue was patched.
Compiler-induced timing side channel in Mbed TLS through 4.0.0 and TF-PSA-Crypto through 1.0.0 allows information disclosure of RSA private keys and CBC/ECB-decrypted plaintext when LLVM's select-optimize feature is enabled during compilation. The vulnerability arises from compiler optimization that violates constant-time implementation guarantees, potentially exposing cryptographic material to timing analysis attacks despite developers' explicit use of constant-time code patterns.
Issue summary: A timing side-channel which could potentially allow remote recovery of the private key exists in the SM2 algorithm implementation on 64 bit ARM platforms. Rated medium severity (CVSS 6.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
A security vulnerability in OpenSSL 3.0.0 through 3.3.2 on the PowerPC architecture (CVSS 5.3). Remediation should follow standard vulnerability management procedures.
Issue summary: A timing side-channel which could potentially allow recovering the private key exists in the ECDSA signature computation. Rated medium severity (CVSS 4.1), this vulnerability is low attack complexity. No vendor patch available.
A vulnerability was found in Ruby. Rated high severity (CVSS 7.4), this vulnerability is remotely exploitable, no authentication required. No vendor patch available.
