UBUNTU-CVE-2026-55653

A flaw was found in OpenSSH. A malicious SSH server can exploit a double free vulnerability in the Diffie-Hellman Group Exchange DH-GEX client path. This occurs during FIPS Federal Information Processing Standards mode known-group validation when the client processes attacker-controlled DH-GEX...

PT-2026-47840

Name of the Vulnerable Software and Affected Versions OpenSSL FIPS modules versions 3.0, 3.4, 3.5, 3.6, and 4.0 Description When the EVP PKEY derive set peer function is called with a DHX X9.42 peer key, the software fails to properly verify subgroup membership. Specifically, the check Y^q ≡ 1 mo...

Name of the Vulnerable Software and Affected Versions: macOS versions prior to 10.13 iOS versions prior to 11.4 Android versions prior to the 2018-06-05 patch Description: The issue is related to incorrect validation of cryptographic signatures in Bluetooth drivers for Android, macOS, and iOS...

LOGJAM: TLS connections which support export grade DHE key-exchange are vulnerable to MITM attacks

A flaw was found in the way the TLS protocol composes the Diffie-Hellman exchange for both export and non-export grade cipher suites. An attacker could use this flaw to downgrade a DHE connection to use export-grade key sizes, which could then be broken by sufficient pre-computation. This can lea...

nss: Do not allow p-1 as a public DH value (MFSA 2014-12)

It was found that NSS accepted weak Diffie-Hellman Key exchange DHKE parameters. This could possibly lead to weak encryption being used in communication between the client and the server...

Triple Handshake TLS Attacks Target Resumption, Renegotiation

A team of researchers has published a paper that explains a number of attacks against websites and Web-based applications running TLS. The researchers’ techniques do not exploit implementation errors, the most common attack vector against encryption securing online communication, instead focus on...
