FreeS/WAN, Openswan, strongSwan: Vulnerabilities in certificate handling

Package(s):freeswan CVE #(s):
Created:June 26, 2004 Updated:July 15, 2004
Description: FreeS/WAN, Openswan, strongSwan and Super-FreeS/WAN contain two bugs when authenticating PKCS#7 certificates. This could allow an attacker to authenticate with a fake certificate. All these IPsec implementations have several bugs in the verify_x509cert() function, which performs certificate validation, that make them vulnerable to malicious PKCS#7 wrapped objects. With a carefully crafted certificate payload an attacker can successfully authenticate against FreeS/WAN, Openswan, strongSwan or Super-FreeS/WAN, or make the daemon go into an endless loop.
