----------------------------------------

             Summary: Large SIP packet received via pjsip over websocket crashes Asterisk 
                 Key: ASTERISK-25122
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-25122
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Resources/res_pjsip_transport_websocket
    Affects Versions: 13.3.2, SVN, 13.4.0
         Environment: Debian 8, pjsip 2.4
            Reporter: Ivan Poddubny


A regression introduced in 13.2.0 causes a crash when pjsip receives a SIP packet over websocket that is larger than PJSIP_MAX_PKT_LEN. The packet is truncated but the len field in pkg_info is not, thus leading to memory corruption and a segfault.
