1. A race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write (COW) breakage of private read-only memory mappings. An unprivileged local user could use this flaw to gain write access to otherwise read-only memory mappings and thus increase their privileges on the system.
2. CA PAM is not vulnerable to this serious attack as the appliance is locked down and users cannot SSH to it. Thus without this access no vulnerabilities can be exploited.
