librenswan: IKEv2 Denial of Service via malformed fragmentation

A flaw was found in Libreswan's IKEv2 fragment reassembly mechanism. When a VPN gateway processes incoming split network packets fragments containing unexpected data, an off-by-one boundary validation error triggers an internal program safety check assertion failure. A remote, unauthenticated...

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,...

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...

libreswan: badly formatted X.509 certificate can cause an assertion failure that crashes the daemon process

A flaw was found in Libreswan. An unauthenticated remote attacker can send a specially crafted X.509 certificate payload during an IKEv1 or IKEv2 exchange. This flaw occurs when Libreswan is operating in FIPS Federal Information Processing Standards mode and processing a certificate with an inval...
