CVE-2015-3339
Published: 21 April 2015
Race condition in the prepare_binprm function in fs/exec.c in the Linux kernel before 3.19.6 allows local users to gain privileges by executing a setuid program at a time instant when a chown to root is in progress, and the ownership is changed but the setuid bit is not yet stripped.
From the Ubuntu security team
A race condition between chown() and execve() was discovered in the Linux kernel. A local attacker could exploit this race by using chown on a setuid-user-binary to gain administrative privileges.
