| CVE-2004-0054 | 1 Cisco | 1 Ios | 2025-04-03 | N/A |
| Multiple vulnerabilities in the H.323 protocol implementation for Cisco IOS 11.3T through 12.2T allow remote attackers to cause a denial of service and possibly execute arbitrary code, as demonstrated by the NISCC/OUSPG PROTOS test suite for the H.225 protocol. | ||||
| CVE-1999-1306 | 1 Cisco | 1 Ios | 2025-04-03 | 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-2002-1358 | 7 Cisco, Fissh, Intersoft and 4 more | 7 Ios, Ssh Client, Securenetterm and 4 more | 2025-04-03 | N/A |
| Multiple SSH2 servers and clients do not properly handle lists with empty elements or strings, which may allow remote attackers to cause a denial of service or possibly execute arbitrary code, as demonstrated by the SSHredder SSH protocol test suite. | ||||
| CVE-2005-2451 | 1 Cisco | 2 Ios, Ios Xr | 2025-04-03 | N/A |
| Cisco IOS 12.0 through 12.4 and IOS XR before 3.2, with IPv6 enabled, allows remote attackers on a local network segment to cause a denial of service (device reload) and possibly execute arbitrary code via a crafted IPv6 packet. | ||||
| CVE-2000-0984 | 1 Cisco | 1 Ios | 2025-04-03 | N/A |
| The HTTP server in Cisco IOS 12.0 through 12.1 allows local users to cause a denial of service (crash and reload) via a URL containing a "?/" string. | ||||
| CVE-2006-0486 | 1 Cisco | 1 Ios | 2025-04-03 | N/A |
| Certain Cisco IOS releases in 12.2S based trains with maintenance release number 25 and later, 12.3T based trains, and 12.4 based trains reuse a Tcl Shell process across login sessions of different local users on the same terminal if the first user does not use tclquit before exiting, which may cause subsequent local users to execute unintended commands or bypass AAA command authorization checks, aka Bug ID CSCef77770. | ||||
| CVE-2006-0485 | 1 Cisco | 1 Ios | 2025-04-03 | N/A |
| The TCL shell in Cisco IOS 12.2(14)S before 12.2(14)S16, 12.2(18)S before 12.2(18)S11, and certain other releases before 25 January 2006 does not perform Authentication, Authorization, and Accounting (AAA) command authorization checks, which may allow local users to execute IOS EXEC commands that were prohibited via the AAA configuration, aka Bug ID CSCeh73049. | ||||
| CVE-2004-0244 | 1 Cisco | 1 Ios | 2025-04-03 | N/A |
| Cisco 6000, 6500, and 7600 series systems with Multilayer Switch Feature Card 2 (MSFC2) and a FlexWAN or OSM module allow local users to cause a denial of service (hang or reset) by sending a layer 2 frame packet that encapsulates a layer 3 packet, but has inconsistent length values with that packet. | ||||
| CVE-2004-0079 | 23 4d, Apple, Avaya and 20 more | 67 Webstar, Mac Os X, Mac Os X Server and 64 more | 2025-04-03 | 7.5 High |
| The do_change_cipher_spec function in OpenSSL 0.9.6c to 0.9.6k, and 0.9.7a to 0.9.7c, allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that triggers a null dereference. | ||||

| Vulnerability in Cisco IOS 11.1CC and 11.1CT with distributed fast switching (DFS) enabled allows remote attackers to bypass certain access control lists when the router switches traffic from a DFS-enabled interface to an interface that does not have DFS enabled, as described by Cisco bug CSCdk35564. | ||||
| CVE-2006-0340 | 1 Cisco | 1 Ios | 2025-04-03 | N/A |

| CVE-2002-2053 | 1 Cisco | 1 Ios | 2025-04-03 | N/A |
| The design of the Hot Standby Routing Protocol (HSRP), as implemented on Cisco IOS 12.1, when using IRPAS, allows remote attackers to cause a denial of service (CPU consumption) via a router with the same IP address as the interface on which HSRP is running, which causes a loop. | ||||
| CVE-2002-2315 | 1 Cisco | 1 Ios | 2025-04-03 | N/A |
