CVSS v3.1 |
| Cisco IOS XR 4.1.2 through 5.1.1 on ASR 9000 devices, when a Trident-based line card is used, allows remote attackers to cause a denial of service (NP chip and line card reload) via malformed IPv6 packets, aka Bug ID CSCun71928. |
| The Zone-Based Firewall (ZBFW) functionality in Cisco IOS, possibly 15.4 and earlier, and IOS XE, possibly 3.13 and earlier, mishandles zone checking for existing sessions, which allows remote attackers to bypass intended resource-access restrictions via spoofed traffic that matches one of these sessions, aka Bug IDs CSCun94946 and CSCun96847. |
| Cisco IOS XR does not properly throttle ICMPv6 redirect packets, which allows remote attackers to cause a denial of service (IPv4 and IPv6 transit outage) via crafted redirect messages, aka Bug ID CSCum14266. |
| Cisco IOS 15.1(2)SY3 and earlier, when used with Supervisor Engine 2T (aka Sup2T) on Catalyst 6500 devices, allows remote attackers to cause a denial of service (device crash) via crafted multicast packets, aka Bug ID CSCuf60783. |
| Cisco IOS before 15.3(1)T, when media flow-around is not used, allows remote attackers to cause a denial of service (media loops and stack memory corruption) via VoIP traffic, aka Bug ID CSCub45809. |
| The IKEv1 state machine in Cisco IOS 15.4 through 15.6 and IOS XE 3.15 through 3.17 allows remote attackers to cause a denial of service (IPsec connection termination) via a crafted IKEv1 packet to a tunnel endpoint, aka Bug ID CSCuw08236. |
| The SNMP implementation in Cisco IOS 15.1(2)SG4 on Catalyst 4500 devices, when single-switch Virtual Switching System (VSS) is configured, allows remote authenticated users to cause a denial of service (device crash) by performing SNMP polling, aka Bug ID CSCuq04574. |
| Cisco IOS XE before 2.2.3 on ASR 1000 devices allows remote attackers to cause a denial of service (Embedded Services Processor crash) via a crafted (1) IPv4 or (2) IPv6 packet, aka Bug ID CSCsw69990. |
| Cisco IOS XE before 2.2.3 on ASR 1000 devices allows remote attackers to cause a denial of service (Embedded Services Processor crash) via a crafted IPv4 UDP packet, aka Bug ID CSCsw95482. |
| The RADIUS client implementation in Cisco IOS 15.4(3)M2.2, when a shared RADIUS secret is configured, allows remote RADIUS servers to cause a denial of service (device reload) via malformed answers, aka Bug ID CSCuu59324. |
| Cisco IOS XE before 2.2.3 on ASR 1000 devices allows remote attackers to cause a denial of service (Embedded Services Processor crash) via a crafted L2TP packet, aka Bug IDs CSCsw95722 and CSCsw95496. |
| Cisco IOS before 15.1(1)SY, when Multicast Listener Discovery (MLD) snooping is enabled, allows remote attackers to cause a denial of service (CPU consumption or device crash) via MLD packets on a network that contains many IPv6 hosts, aka Bug ID CSCtr88193. |
| A vulnerability in the Zone-Based Firewall feature of Cisco IOS and Cisco IOS XE Software could allow an unauthenticated, remote attacker to pass traffic that should otherwise have been dropped based on the configuration. More Information: CSCuz21015. Known Affected Releases: 15.3(3)M3. Known Fixed Releases: 15.6(2)T0.1 15.6(2.0.1a)T0 15.6(2.19)T 15.6(3)M. |
| The SNMPv2 implementation in Cisco IOS XR allows remote authenticated users to cause a denial of service (snmpd daemon reload) via a malformed SNMP packet, aka Bug ID CSCur25858. |
| The encryption-processing feature in Cisco libSRTP before 1.5.3 allows remote attackers to cause a denial of service via crafted fields in SRTP packets, aka Bug ID CSCux00686. |
| A vulnerability in the HTTP 2.0 request handling code of Cisco IOS XR Software could allow an unauthenticated, remote attacker to cause the Event Management Service daemon (emsd) to crash, resulting in a denial of service (DoS) condition. More Information: CSCvb14425. Known Affected Releases: 6.1.1.BASE. Known Fixed Releases: 6.1.2.6i.MGBL 6.1.22.9i.MGBL 6.2.1.14i.MGBL. |
| The Authentication Proxy feature in Cisco IOS does not properly handle invalid AAA return codes from RADIUS and TACACS+ servers, which allows remote attackers to bypass authentication in opportunistic circumstances via a connection attempt that triggers an invalid code, as demonstrated by a connection attempt with a blank password, aka Bug IDs CSCuo09400 and CSCun16016. |
| Cisco IOS XR allows remote attackers to cause a denial of service (RSVP process reload) via a malformed RSVP packet, aka Bug ID CSCur69192. |
| The RADIUS implementation in Cisco IOS and IOS XE allows remote attackers to cause a denial of service (device reload) via crafted IPv6 Attributes in Access-Accept packets, aka Bug IDs CSCur84322 and CSCur27693. |
| The Autonomic Networking Infrastructure (ANI) implementation in Cisco IOS allows remote attackers to trigger self-referential adjacencies via a crafted Autonomic Networking (AN) message, aka Bug ID CSCup62157. |
