The Asterisk Development Team has released, Asterisk 188.8.131.52 and is available for immediate download from Digium Downloads.
This release addresses a merge issue from trunk to 184.108.40.206 that caused memory to be freed that should not be. In trunk, pkt->data is an ast_str, but in 1.6.0, it is allocated in the same chunk of memory as the sip_pkt. Only the 1.6.0 branch of Asterisk is effected by this issue.
Summary of the changes in this release
