CVE-2012-2127
Published: 21 June 2012
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.
From the Ubuntu Security Team
Vadim Ponomarev discovered a flaw in the Linux kernel causing a reference leak when PID namespaces are used. A remote attacker could exploit this flaw causing a denial of service.
