Title
PJSIP has use-after-free vulnerability in SRTP media transport
Summary
PJSIP is a free and open source multimedia communication library written in C with high level API in C, C++, Java, C#, and Python languages. SRTP is a higher level media transport which is stacked upon a lower level media transport such as UDP and ICE. Currently a higher level transport is not synchronized with its lower level transport that may introduce use-after-free issue. This vulnerability affects applications that have SRTP capability (`PJMEDIA_HAS_SRTP` is set) and use underlying media transport other than UDP. This vulnerability’s impact may range from unexpected application termination to control flow hijack/memory corruption. The patch is available as a commit in the master branch.

Actualmente, un transporte de nivel superior no est\u00e1 sincronizado con su transporte de nivel inferior, lo que puede introducir un problema de use-after-free. Esta vulnerabilidad afecta a las aplicaciones que tienen capacidad SRTP (`PJMEDIA_HAS_SRTP` est\u00e1 configurado) y utilizan transporte de medios subyacente distinto de UDP. El impacto de esta vulnerabilidad puede variar desde la terminaci\u00f3n inesperada de la aplicaci\u00f3n hasta el secuestro de flujo de control/corrupci\u00f3n de memoria. El parche est\u00e1 disponible como commit en la rama master."
