Descriptions

An FR-GV-204 issue in FreeRADIUS 2.x before 2.2.10 allows "DHCP - Memory leak in fr_dhcp_decode()" and a denial of service.

Un problema FR-GV-204 en FreeRADIUS versión 2.x anterior a 2.2.10, permite una "DHCP - Memory leak in fr_dhcp_decode()" y una denegación de servicio.

A memory leak flaw was found in the way FreeRADIUS server handles decoding of DHCP packets. A remote attacker could use this flaw to cause the FreeRADIUS server to consume an increasing amount of memory resources over time, possibly leading to a crash due to memory exhaustion, by sending specially crafted DHCP packets.

Security Fix: An out-of-bounds write flaw was found in the way FreeRADIUS server handled certain attributes in request packets. A remote attacker could use this flaw to crash the FreeRADIUS server or to execute arbitrary code in the context of the FreeRADIUS server process by sending a specially crafted request packet.
