Descriptions
Buffer overflow in lib/flow.c in ovs-vswitchd in Open vSwitch 2.2.x and 2.3.x before 2.3.3 and 2.4.x before 2.4.1 allows remote attackers to execute arbitrary code via crafted MPLS packets, as demonstrated by a long string in an ovs-appctl command.
Desbordamiento de buffer en lib/flow.c en ovs-vswitchd en Open vSwitch 2.2.x y 2.3.x en versiones anteriores a 2.3.3 y 2.4.x en versiones anteriores a 2.4.1 permite a atacantes remotos ejecutar código arbitrario a través de paquetes MPLS manipulados, según lo demostrado por una cadena larga en un comando ovs-appctl.
A buffer overflow flaw was discovered in the OVS processing of MPLS labels. A remote attacker able to deliver a frame containing a malicious MPLS label that would be processed by OVS could trigger the flaw and use the resulting memory corruption to cause a denial of service (DoS) or, possibly, execute arbitrary code.
