VAR-201705-1387
Vulnerability from variot - Updated: 2023-12-18 13:24In Open vSwitch (OvS) 2.5.0, a malformed IP packet can cause the switch to read past the end of the packet buffer due to an unsigned integer underflow in lib/flow.c in the function miniflow_extract, permitting remote bypass of the access control list enforced by the switch. Open vSwitch (OvS) Contains a buffer error vulnerability.Information is acquired, information is acquired, information is altered, and service operation is interrupted (DoS) There is a possibility of being put into a state. Open vSwitch (OvS) is a multi-layer virtual switch product based on open source technology (according to the Apache2.0 license). It supports large-scale network automation, standard management interfaces and protocols, etc. through programming extensions. There is a security vulnerability in the 'miniflow_extract' function of lib/flow.c file in OvS 2.5.0 version. A remote attacker could exploit this vulnerability to bypass access control lists
