Descriptions
PJSIP is a free and open source multimedia communication library written in C language implementing standard based protocols such as SIP, SDP, RTP, STUN, TURN, and ICE. In versions up to and including 2.11.1 when in a dialog set (or forking) scenario, a hash key shared by multiple UAC dialogs can potentially be prematurely freed when one of the dialogs is destroyed . The issue may cause a dialog set to be registered in the hash table multiple times (with different hash keys) leading to undefined behavior such as dialog list collision which eventually leading to endless loop. A patch is available in commit db3235953baa56d2fb0e276ca510fefca751643f which will be included in the next release. There are no known workarounds for this issue.
PJSIP es una biblioteca de comunicación multimedia gratuita y de código abierto escrita en lenguaje C que implementa protocolos basados en estándares como SIP, SDP, RTP, STUN, TURN e ICE. En las versiones hasta la versión 2.11.1 inclusive, cuando se encuentra en un escenario de conjunto de diálogos (o bifurcación), una clave hash compartida por varios diálogos de UAC puede potencialmente liberarse prematuramente cuando se destruye uno de los diálogos. El problema puede hacer que un conjunto de diálogos se registre en la tabla hash varias veces (con diferentes claves hash), lo que lleva a un comportamiento indefinido, como la colisión de la lista de diálogos, lo que eventualmente conduce a un bucle sin fin. Hay un parche disponible en la confirmación db3235953baa56d2fb0e276ca510fefca751643f que se incluirá en la próxima versión. No hay soluciones alternativas conocidas para este problema
