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."},{"lang":"es","value":"PJSIP es una librería de comunicación multimedia gratuita y de código abierto escrita en C con API de alto nivel en los lenguajes C, C++, Java, C# y Python. SRTP es un transporte de medios de nivel superior que se apila sobre un transporte de medios de nivel inferior, como UDP e ICE. Actualmente, un transporte de nivel superior no está 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` está configurado) y utilizan transporte de medios subyacente distinto de UDP.
