AZL-91773 CVE-2026-50721 affecting package libreswan for versions less than 4.15-2

Libreswan, via the function RSAauthenticatehashsignaturerawrsa, did not correctly verify the length of the authentication hash when the SIG payload of an IKEv1 packet was encoded using PKCS 1 RSA Encryption as per RFC 2313. A remote attacker can use a variation on the Bleichenbacher attack to for...

The verify function in the RSA package for Python (Python-RSA) before 3.3 allows attackers to spoof signatures with a small public exponent via crafted signature padding, aka a BERserk attack.

SUSE CVE-2018-15836

In verifysignedhash in lib/liboswkeys/signatures.c in Openswan before 2.6.50.1, the RSA implementation does not verify the value of padding string during PKCS1 v1.5 signature verification. Consequently, a remote attacker can forge signatures when small public exponents are being used. IKEv2...

CVE-2018-16151

In verifyemsapkcs1signature in gmprsapublickey.c in the gmp plugin in strongSwan 4.x and 5.x before 5.7.0, the RSA implementation based on GMP does not reject excess data after the encoded algorithm OID during PKCS1 v1.5 signature verification. Similar to the flaw in the same version of strongSwa...
