CVE-1999-0445 1 Cisco 1 Ios 2023-12-10 5.0 MEDIUM N/A
In Cisco routers under some versions of IOS 12.0 running NAT, some packets may not be filtered by input access list filters.
CVE-2002-2052 1 Cisco 1 Ios 2023-12-10 5.0 MEDIUM N/A
Cisco 2611 router running IOS 12.1(6.5), possibly an interim release, allows remote attackers to cause a denial of service via port scans such as (1) scanning all ports on a single host and (2) scanning a network of hosts for a single open port through the router. NOTE: the vendor could not reproduce this issue, saying that the original reporter was using an interim release of the software.
CVE-2000-0380 1 Cisco 1 Ios 2023-12-10 7.1 HIGH N/A
The IOS HTTP service in Cisco routers and switches running IOS 11.1 through 12.1 allows remote attackers to cause a denial of service by requesting a URL that contains a %% string.
CVE-2004-0081 23 4d, Apple, Avaya and 20 more 66 Webstar, Mac Os X, Mac Os X Server and 63 more 2023-12-10 5.0 MEDIUM N/A
OpenSSL 0.9.6 before 0.9.6d does not properly handle unknown message types, which allows remote attackers to cause a denial of service (infinite loop), as demonstrated using the Codenomicon TLS Test Tool.
CVE-2001-0750 1 Cisco 1 Ios 2023-12-10 5.0 MEDIUM N/A
Cisco IOS 12.1(2)T, 12.1(3)T allow remote attackers to cause a denial of service (reload) via a connection to TCP ports 3100-3999, 5100-5999, 7100-7999 and 10100-10999.
CVE-1999-1129 1 Cisco 2 Catalyst 2900 Vlan, Ios 2023-12-10 7.5 HIGH N/A
Cisco Catalyst 2900 Virtual LAN (VLAN) switches allow remote attackers to inject 802.1q frames into another VLAN by forging the VLAN identifier in the trunking tag.
CVE-2004-0054 1 Cisco 1 Ios 2023-12-10 7.5 HIGH 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-2003-0647 1 Cisco 1 Ios 2023-12-10 7.5 HIGH N/A
Buffer overflow in the HTTP server for Cisco IOS 12.2 and earlier allows remote attackers to execute arbitrary code via an extremely long (2GB) HTTP GET request.
CVE-2002-2208 2 Cisco, Extended Interior Gateway Routing Protocol 2 Ios, Extended Interior Gateway Routing Protocol 2023-12-10 7.8 HIGH N/A
Extended Interior Gateway Routing Protocol (EIGRP), as implemented in Cisco IOS 11.3 through 12.2 and other products, allows remote attackers to cause a denial of service (flood) by sending a large number of spoofed EIGRP neighbor announcements, which results in an ARP storm on the local network.
CVE-1999-0016 6 Cisco, Gnu, Hp and 3 more 8 Ios, Inet, Hp-ux and 5 more 2023-12-10 5.0 MEDIUM N/A
Land IP denial of service.
CVE-1999-0775 1 Cisco 1 Ios 2023-12-10 10.0 HIGH N/A
Cisco Gigabit Switch routers running IOS allow remote attackers to forward unauthorized packets due to improper handling of the "established" keyword in an access list.
CVE-2001-0711 1 Cisco 1 Ios 2023-12-10 5.0 MEDIUM N/A
Cisco IOS 11.x and 12.0 with ATM support allows attackers to cause a denial of service via the undocumented Interim Local Management Interface (ILMI) SNMP community string.
CVE-1999-0230 1 Cisco 1 Ios 2023-12-10 5.0 MEDIUM N/A
Buffer overflow in Cisco 7xx routers through the telnet service.

OpenSSL 0.9.6k allows remote attackers to cause a denial of service (crash via large recursion) via malformed ASN.1 sequences.
CVE-2000-0268 1 Cisco 12 3660 Router, 7100 Router, 7200 Router and 9 more 2023-12-10 5.0 MEDIUM 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-2001-0650 1 Cisco 1 Ios 2023-12-10 5.0 MEDIUM N/A
Cisco devices IOS 12.0 and earlier allow a remote attacker to cause a crash, or bad route updates, via malformed BGP updates with unrecognized transitive attribute.
CVE-2003-0567 1 Cisco 3 Ios, Ons 15454 Optical Transport Platform, Optical Networking Systems Software 2023-12-10 7.8 HIGH 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-2003-1109 1 Cisco 4 Ios, Ip Phone 7940, Ip Phone 7960 and 1 more 2023-12-10 7.5 HIGH 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.
