Envoy Security Vulnerabilities

Envoy is an open source distributed proxy server. A security vulnerability exists in Envoy versions prior to 1.30.4, 1.29.7, 1.28.5, and 1.27.7, which stems from a reference to memory that has been freed when using the cookie attribute when configuring a routing hash policy, resulting in the...

SUSE CVE-2009-4272

A certain Red Hat patch for net/ipv4/route.c in the Linux kernel 2.6.18 on Red Hat Enterprise Linux RHEL 5 allows remote attackers to cause a denial of service deadlock via crafted packets that force collisions in the IPv4 routing hash table, and trigger a routing "emergency" in which a hash chai...
