Descriptions

PJSIP is a free and open source multimedia communication library written in C. A denial-of-service vulnerability affects applications on a 32-bit systems that use PJSIP versions 2.12 and prior to play/read invalid WAV files. The vulnerability occurs when reading WAV file data chunks with length greater than 31-bit integers. The vulnerability does not affect 64-bit apps and should not affect apps that only plays trusted WAV files. A patch is available on the `master` branch of the `pjsip/project` GitHub repository. As a workaround, apps can reject a WAV file received from an unknown source or validate the file first.

PJSIP es una biblioteca de comunicación multimedia gratuita y de código abierto escrita en C. Una vulnerabilidad de denegación de servicio afecta a las aplicaciones en sistemas de 32 bits que usan PJSIP versiones 2.12 y anteriores para reproducir/leer archivos WAV no válidos. La vulnerabilidad es producida cuando son leídos trozos de datos de archivos WAV con una longitud superior a los enteros de 31 bits. La vulnerabilidad no afecta a aplicaciones de 64 bits y no debería afectar a las aplicaciones que sólo reproducen archivos WAV confiables. Se presenta un parche disponible en la rama "master" del repositorio GitHub "pjsip/project". Como medida de mitigación, las aplicaciones pueden rechazar un archivo WAV recibido de una fuente desconocida o comprobar primero el archivo
