| Buffer overflow in Cisco IOS 11.2.x to 12.0.x allows remote attackers to cause a denial of service and possibly execute commands via a large number of OSPF neighbor announcements. | ||||
| CVE-2005-0197 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Cisco IOS 12.1T, 12.2, 12.2T, 12.3 and 12.3T, with Multi Protocol Label Switching (MPLS) installed but disabled, allows remote attackers to cause a denial of service (device reload) via a crafted packet sent to the disabled interface. | ||||
| CVE-1999-0230 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Buffer overflow in Cisco 7xx routers through the telnet service. | ||||
| CVE-2004-0054 | 1 Cisco | 1 Ios | 2026-04-16 | 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-1999-0159 | 1 Cisco | 1 Ios | 2026-04-16 | 3.5 Low |
| Attackers can crash a Cisco IOS router or device, provided they can get to an interactive prompt (such as a login). This applies to some IOS 9.x, 10.x, and 11.x releases. | ||||
| 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-2001-1071 | 1 Cisco | 2 Catos, Ios | 2026-04-16 | N/A |
| Cisco IOS 12.2 and earlier running Cisco Discovery Protocol (CDP) allows remote attackers to cause a denial of service (memory consumption) via a flood of CDP neighbor announcements. | ||||
| CVE-2004-0710 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| IP Security VPN Services Module (VPNSM) in Cisco Catalyst 6500 Series Switch and the Cisco 7600 Series Internet Routers running IOS before 12.2(17b)SXA, before 12.2(17d)SXB, or before 12.2(14)SY03 could allow remote attackers to cause a denial of service (device crash and reload) via a malformed Internet Key Exchange (IKE) packet. | ||||
| CVE-2003-1398 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Cisco IOS 12.0 through 12.2, when IP routing is disabled, accepts false ICMP redirect messages, which allows remote attackers to cause a denial of service (network routing modification). | ||||
| CVE-2004-0079 | 23 4d, Apple, Avaya and 20 more | 67 Webstar, Mac Os X, Mac Os X Server and 64 more | 2026-04-16 | 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. | ||||
| CVE-2002-2239 | 1 Cisco | 3 Catalyst 6500, Catalyst 7600, Ios | 2026-04-16 | N/A |
| The Cisco Optical Service Module (OSM) for the Catalyst 6500 and 7600 series running Cisco IOS 12.1(8)E through 12.1(13.4)E allows remote attackers to cause a denial of service (hang) via a malformed packet. | ||||
| CVE-2006-4775 | 1 Cisco | 2 Catos, Ios | 2026-04-16 | N/A |
| The VLAN Trunking Protocol (VTP) feature in Cisco IOS 12.1(19) and CatOS allows remote attackers to cause a denial of service by sending a VTP update with a revision value of 0x7FFFFFFF, which is incremented to 0x80000000 and is interpreted as a negative number in a signed context. | ||||
| CVE-2003-1109 | 1 Cisco | 4 Ios, Ip Phone 7940, Ip Phone 7960 and 1 more | 2026-04-16 | N/A |
| The Session Initiation Protocol (SIP) implementation in multiple Cisco products including IP Phone models 7940 and 7960, IOS versions in the 12.2 train, and Secure PIX 5.2.9 to 6.2.2 allows remote attackers to cause a denial of service and possibly execute arbitrary code via crafted INVITE messages, as demonstrated by the OUSPG PROTOS c07-sip test suite. | ||||
| CVE-2006-4650 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Cisco IOS 12.0, 12.1, and 12.2, when GRE IP tunneling is used and the RFC2784 compliance fixes are missing, does not verify the offset field of a GRE packet during decapsulation, which leads to an integer overflow that references data from incorrect memory locations, which allows remote attackers to inject crafted packets into the routing queue, possibly bypassing intended router ACLs. | ||||
