CVE-2026-50722
Libreswan is affected by CVE-2026-50722 through RSA_authenticate_hash_signature_pkcs1_1_5_rsa, which fails to properly verify the DER encoding of the ASN.1 digest when the IKEv2 AUTH payload uses RSASSA-PKCS1-v1_5 (RFC 8017). This enables a remote attacker to perform a Bleichenbacher-like variati...
CVE-2026-50722
Libreswan, via the function RSAauthenticatehashsignaturepkcs115rsa, did not correctly verify the DER encoding of the ASN.1 digest when the IKEv2 AUTH payload was encoded using RSASSA-PKCS1-v15 RFC 8017. A remote attacker can use a variation on the Bleichenbacher attack to forge the AUTH payload...

GHSA-4J9M-H44M-2HV8 Steeltoe: OAEP setting silently selects PKCS#1 v1.5 padding
Summary Configuring encrypt:rsa:algorithm=OAEP does not enable OAEP encryption. Due to an incorrect BouncyCastle transformation string, the OAEP setting selects PKCS1 v1.5, which is the same algorithm as the DEFAULT setting. Impact Operators who configure encrypt:rsa:algorithm=OAEP to obtain...
