             Summary: Memory Leak caused by fix for ASTERISK-28445
                 Key: ASTERISK-29049
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-29049
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: pjproject/pjsip
    Affects Versions: 16.2.1
            Reporter: Bernhard Schmidt


I'm not exactly sure whether this affects recent versions where the patch has been merged upstream as well, I can't test that due to ASTERISK-29017 . But I haven't found any subsequent fixes so I think it is quite likely.

In ASTERISK-28445 a one-line fix has been proposed and merged to fix a use-after-free in res_pjsip_session. Backporting this to 16.2.1 in Debian  the fix is leaking memory. Since the patch only changes one line to ast_strdupa a variable but doesn't free it anywhere that's probably the root cause.
