DUHK Attack against Fortinet Products

When devices use ANSI X9.31 RNG which was removed from the list of FIPS-approved random number generation algorithms in January 2016 to generate cryptographic key under a static seed and under use with long-lived security tunnels like SSL/TLS/SSH/IPSec, such devices are vulnerable to the DUHK...

CVE-2016-6466

A vulnerability in the IPsec component of StarOS for Cisco ASR 5000 Series routers could allow an unauthenticated, remote attacker to terminate all active IPsec VPN tunnels and prevent new tunnels from establishing, resulting in a denial of service DoS condition. This vulnerability affects the...

OpenSSL Patches High-Severity OCSP Bug, Mitigates SWEET32 Attack

A vulnerability in the OpenSSL implementation of the Online Certificate Status Protocol OCSP was patched this week, closing a denial-of-service weakness in affected servers. The patch was the most severe of 14 released yesterday by OpenSSL. OCSP is an alternative in many cases to Certificate...

Windows IPSec Denial of Service Vulnerability

A denial of service vulnerability exists in the way that Windows handles objects in memory. An attacker who successfully exploited the vulnerability could cause a target system to stop responding. Note that the denial of service condition would not allow an attacker to execute code or to elevate...
