Descriptions

rsyslog before 7.6.6 and 8.x before 8.4.1 and sysklogd 1.5 and earlier allows remote attackers to cause a denial of service (crash), possibly execute arbitrary code, or have other unspecified impact via a crafted priority (PRI) value that triggers an out-of-bounds array access.

rsyslog anterior a 7.6.6 y 8.x anterior a 8.4.1 y sysklogd 1.5 y anteriores permiten a atacantes remotos causar una denegación de servicio (caída), posiblemente ejecutar código arbitrario o tener otro impacto no especificado a través de un valor de prioridad (PRI) manipulado que provoca un acceso a array fuera de rango.

A flaw was found in the way rsyslog handled invalid log message priority values. In certain configurations, a local attacker, or a remote attacker able to connect to the rsyslog port, could use this flaw to crash the rsyslog daemon or, potentially in rsyslog 7.x, execute arbitrary code as the user running the rsyslog daemon.
