librenswan: IKEv2 Denial of Service via RSA-SHA1 (PKCS#1 RSASSA-PKCS1-v1_5) authentication payload

A flaw was found in Libreswan's implementation of IKEv2 authentication when processing signatures utilizing the RSASSA-PKCS1-v15 scheme. The RSAauthenticatehashsignaturepkcs115rsa function does not correctly validate the DER encoding of the ASN.1 digest. A remote, unauthenticated attacker could...

CVE-2026-82876

CVE-2026-82876 affects the Phison PS3111-S11 SSD controller. The firmware's RSA signature verification uses a public modulus embedded within the firmware image rather than anchored in immutable storage. An attacker with local access (high privileges required) can generate arbitrary RSA key pairs,...

Improper Verification Of Cryptographic Signature

Bouncy Castle for Java is vulnerable to Improper Verification of Cryptographic Signature. The vulnerability is due to RSA PKCS1 signature verification skipping the last two hash bytes when processing the NULL-omitted path, which allows an attacker to forge or bypass RSA signature verification by...

librenswan: IKEv1 Denial of Service via RSA-SHA1 (PKCS#1 Version 1.5 Encrypted) authentication payload

A flaw was found in Libreswan's implementation of IKEv1 authentication via raw RSA signatures. When processing an IKEv1 packet using PKCS 1 v1.5 RSA encryption, the RSAauthenticatehashsignaturerawrsa function fails to properly validate the length of the authentication hash. A remote,...

Important: swiftlang

Issue Overview: When initializing an RSA public key from DER or PEM bytes throws an error, the EVPPKEY is double-freed: first in the catch block, then in the deinit. This can lead to a crash on future memory allocations. This double-free manifests when BoringSSL cannot decode the public key from...
