Descriptions

PJSIP is a free and open source multimedia communication library written in C language. In versions prior to and including 2.12 PJSIP there is a stack-buffer overflow vulnerability which only impacts PJSIP users who accept hashed digest credentials (credentials with data_type `PJSIP_CRED_DATA_DIGEST`). This issue has been patched in the master branch of the PJSIP repository and will be included with the next release. Users unable to upgrade need to check that the hashed digest data length must be equal to `PJSIP_MD5STRLEN` before passing to PJSIP.

PJSIP es una biblioteca de comunicación multimedia gratuita y de código abierto escrita en lenguaje C. En las versiones anteriores a 2.12 de PJSIP, se presenta una vulnerabilidad de desbordamiento del buffer de pila que sólo afecta a usuarios de PJSIP que aceptan credenciales de resumen (data_type "PJSIP_CRED_DATA_DIGEST"). Este problema ha sido parcheado en la rama maestra del repositorio PJSIP y será incluida en la próxima versión. Los usuarios que no puedan actualizarse deben comprobar que la longitud de los datos del resumen hash debe ser igual a "PJSIP_MD5STRLEN" antes de pasar a PJSIP
