Description:
Thomas Walpuski has reported a vulnerability in strongSwan, Openswan, and FreeS/WAN, which potentially can be exploited by malicious people to bypass certain security restrictions.
The vulnerability is caused due to two authentication errors within the "verify_x509cert()" function when verifying certificates. This may reportedly cause a specially crafted, invalid certificate to be accepted or make the daemon enter an infinite loop.
The following products are affected:
* Super FreeS/WAN 1.x (all revisions with X.509 patch)
* Openswan 1.x (prior to version 1.0.6)
* Openswan 2.x (prior to version 2.1.4)
* strongSwan 2.x (prior to version 2.1.3)
* All versions of FreeS/WAN 1.x with X.509 patch (prior to 0.9.41)
* All versions of FreeS/WAN 2.x with X.509 patch (prior to 1.6.1)
