DescriptionIn verify_signed_hash() in lib/liboswkeys/signatures.c in Openswan before 22.214.171.124, the RSA implementation does not verify the value of padding string during PKCS#1 v1.5 signature verification. Consequently, a remote attacker can forge signatures when small public exponents are being used. IKEv2 signature verification is affected when RAW RSA keys are used.
