libpjsip.so is affected by a use-after-free vulnerability. This vulnerability is due to the usage of invalid inputs in the pjsip_ua_unregister_dlg function in sip_ua_layer.c file allowing to register to hash table multiple times with different keys resulting in dialog list collision and leading to an endless loop.
