| CVE-2006-0340 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Unspecified vulnerability in Stack Group Bidding Protocol (SGBP) support in Cisco IOS 12.0 through 12.4 running on various Cisco products, when SGBP is enabled, allows remote attackers on the local network to cause a denial of service (device hang and network traffic loss) via a crafted UDP packet to port 9900. | ||||
| CVE-2004-1111 | 1 Cisco | 10 7200 Router, 7300 Router, 7500 Router and 7 more | 2026-04-16 | N/A |
| Cisco IOS 2.2(18)EW, 12.2(18)EWA, 12.2(14)SZ, 12.2(18)S, 12.2(18)SE, 12.2(18)SV, 12.2(18)SW, and other versions without the "no service dhcp" command, keep undeliverable DHCP packets in the queue instead of dropping them, which allows remote attackers to cause a denial of service (dropped traffic) via multiple undeliverable DHCP packets that exceed the input queue size. | ||||
| CVE-2005-4826 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Unspecified vulnerability in the VLAN Trunking Protocol (VTP) feature in Cisco IOS 12.1(22)EA3 on Catalyst 2950T switches allows remote attackers to cause a denial of service (device reboot) via a crafted Subset-Advert message packet, a different issue than CVE-2006-4774, CVE-2006-4775, and CVE-2006-4776. | ||||
| CVE-2005-1020 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Secure Shell (SSH) 2 in Cisco IOS 12.0 through 12.3 allows remote attackers to cause a denial of service (device reload) (1) via a username that contains a domain name when using a TACACS+ server to authenticate, (2) when a new SSH session is in the login phase and a currently logged in user issues a send command, or (3) when IOS is logging messages and an SSH session is terminated while the server is sending data. | ||||
| CVE-2000-0268 | 1 Cisco | 12 3660 Router, 7100 Router, 7200 Router and 9 more | 2026-04-16 | N/A |
| Cisco IOS 11.x and 12.x allows remote attackers to cause a denial of service by sending the ENVIRON option to the Telnet daemon before it is ready to accept it, which causes the system to reboot. | ||||
| CVE-2003-0567 | 1 Cisco | 3 Ios, Ons 15454 Optical Transport Platform, Optical Networking Systems Software | 2026-04-16 | N/A |
| Cisco IOS 11.x and 12.0 through 12.2 allows remote attackers to cause a denial of service (traffic block) by sending a particular sequence of IPv4 packets to an interface on the device, causing the input queue on that interface to be marked as full. | ||||
| CVE-2001-1183 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| PPTP implementation in Cisco IOS 12.1 and 12.2 allows remote attackers to cause a denial of service (crash) via a malformed packet. | ||||
| CVE-2006-3291 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| The web interface on Cisco IOS 12.3(8)JA and 12.3(8)JA1, as used on the Cisco Wireless Access Point and Wireless Bridge, reconfigures itself when it is changed to use the "Local User List Only (Individual Passwords)" setting, which removes all security and password configurations and allows remote attackers to access the system. | ||||
| CVE-1999-0160 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Some classic Cisco IOS devices have a vulnerability in the PPP CHAP authentication to establish unauthorized PPP connections. | ||||

| CVE-1999-1306 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Cisco IOS 9.1 and earlier does not properly handle extended IP access lists when the IP route cache is enabled and the "established" keyword is set, which could allow attackers to bypass filters. | ||||
| CVE-2005-3669 | 1 Cisco | 8 Adaptive Security Appliance Software, Firewall Services Module, Ios and 5 more | 2026-04-16 | N/A |
| Multiple unspecified vulnerabilities in the Internet Key Exchange version 1 (IKEv1) implementation in multiple Cisco products allow remote attackers to cause a denial of service (device reset) via certain malformed IKE packets, as demonstrated by the PROTOS ISAKMP Test Suite for IKEv1. NOTE: due to the lack of details in the Cisco advisory, it is unclear which of CVE-2005-3666, CVE-2005-3667, and/or CVE-2005-3668 this issue applies to. | ||||
