CVE-2012-2127 at MITRE

Description

fs/proc/root.c in the procfs implementation in the Linux kernel before 3.2 does not properly interact with CLONE_NEWPID clone system calls, which allows remote attackers to cause a denial of service (reference leak and memory consumption) by making many connections to a daemon that uses PID namespaces to isolate clients, as demonstrated by vsftpd.

Note from the SUSE Security Team

This issue affected only kernels with PID namespaces, so SUSE Linux Enterprise 11 SP2 and later. Older products up to and including SUSE Linux Enterprise 11 SP1 were not affected by this problem.
