* lzo: Handle integer overflowLuca Barbato2014-06-23
| | | | | | | get_len can overflow for specially crafted payload. Reported-By: Don A. Baley <donb@securitymouse.com> CC: libav-stable@libav.org
* lzo: fix overflow checking in copy_backptr()Xi Wang2013-03-15
| | | | | | | | | | | | | The check `src > dst' in the form `&c->out[-back] > c->out' invokes pointer overflow, which is undefined behavior in C. Remove the check. Also replace `&c->out[-back] < c->out_start' with a safe form `c->out - c->out_start < back' to avoid overflow.
