Max Vozeler discovered an integer overflow in camel-lock-helper. An user-supplied length value was not validated, so that a value of -1 caused a buffer allocation of 0 bytes; this buffer was then filled by an arbitrary amount of user-supplied data.
A local attacker or a malicious POP3 server could exploit this to execute arbitrary code with root privileges (because camel-lock-helper is installed as setuid root).
