 https://ubuntu.com/security/notices/USN-1390-1
Description:
 The robust futex implementation in the Linux kernel before 2.6.28 does not
 properly handle processes that make exec system calls, which allows local
 users to cause a denial of service or possibly gain privileges by writing
 to a memory location in a child process.
Ubuntu-Description:
 A flaw was found in how the linux kernel handles user-space held futexs. An
 unprivileged user could exploit this flaw to cause a denial of service or
 possibly elevate privileges.
