VAR-201503-0156
Vulnerability from variot - Updated: 2023-12-18 12:38The Service Discovery Gateway (aka mDNS Gateway) in Cisco IOS 12.2, 12.4, 15.0, 15.1, 15.2, 15.3, and 15.4 and IOS XE 3.9.xS and 3.10.xS before 3.10.4S, 3.11.xS before 3.11.3S, 3.12.xS before 3.12.2S, and 3.13.xS before 3.13.1S allows remote attackers to cause a denial of service (device reload) by sending malformed mDNS UDP packets over (1) IPv4 or (2) IPv6, aka Bug ID CSCup70579. Cisco IOS is a popular Internet operating system. Cisco IOS and IOS XE Software are prone to a remote denial-of-service vulnerability. Successful exploits may allow attackers to cause the device to reload, denying service to legitimate users. This issue is being tracked by Cisco Bug ID CSCup70579. Service Discovery Gateway (also known as mDNS Gateway, multicast DNS) is a gateway used to provide how to use common DNS programming interfaces (package format and operation semantics) in a small network without DNS services. The following products and versions are affected: Cisco IOS Releases 12.2, 12.4, 15.0, 15.2, 15.3, 15.4 and IOS XE 3.9.xS, 3.10.xS prior to 3.10.4S, 3.11.xS prior to 3.11.3S Version, 3.12.xS version before 3.12.2S, 3.13.xS version before 3.13.1S

Cisco IOS is a popular Internet operating system. Cisco IOS and IOS XE Software are prone to a remote denial-of-service vulnerability. \nSuccessful exploits may allow attackers to cause the device to reload, denying service to legitimate users. \nThis issue is being tracked by Cisco Bug ID CSCup70579. Service Discovery Gateway (also known as mDNS Gateway, multicast DNS) is a gateway used to provide how to use common DNS programming interfaces (package format and operation semantics) in a small network without DNS services. The following products and versions are affected: Cisco IOS Releases 12.2, 12.4, 15.0, 15.2, 15.3, 15.4 and IOS XE 3.9.xS, 3.10.xS prior to 3.10.4S, 3.11.xS prior to 3.11.3S Version, 3.12.xS version before 3.12.2S, 3.13.xS version before 3.13.1S",
