CVE-2002-1360 7 Cisco, Fissh, Intersoft and 4 more 7 Ios, Ssh Client, Securenetterm and 4 more 2026-04-16 N/A
Multiple SSH2 servers and clients do not properly handle strings with null characters in them when the string length is specified by a length field, which could allow remote attackers to cause a denial of service or possibly execute arbitrary code due to interactions with the use of null-terminated strings as implemented using languages such as C, as demonstrated by the SSHredder SSH protocol test suite.

Heap-based buffer overflow in the VLAN Trunking Protocol (VTP) feature in Cisco IOS 12.1(19) allows remote attackers to execute arbitrary code via a long VLAN name in a VTP type 2 summary advertisement.
CVE-2002-2052 1 Cisco 1 Ios 2026-04-16 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-2005-2841 1 Cisco 1 Ios 2026-04-16 N/A
Buffer overflow in Firewall Authentication Proxy for FTP and/or Telnet Sessions for Cisco IOS 12.2ZH and 12.2ZL, 12.3 and 12.3T, and 12.4 and 12.4T allows remote attackers to cause a denial of service and possibly execute arbitrary code via crafted user authentication credentials.
CVE-2001-0750 1 Cisco 1 Ios 2026-04-16 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-2003-0100 1 Cisco 1 Ios 2026-04-16 N/A
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-2005-0196 1 Cisco 1 Ios 2026-04-16 N/A
Cisco IOS 12.0 through 12.3YL, with BGP enabled and running the bgp log-neighbor-changes command, allows remote attackers to cause a denial of service (device reload) via a malformed BGP packet.
CVE-2000-0380 1 Cisco 1 Ios 2026-04-16 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-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-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-2001-1097 1 Cisco 1 Ios 2026-04-16 N/A
Cisco routers and switches running IOS 12.0 through 12.2.1 allows a remote attacker to cause a denial of service via a flood of UDP packets.
CVE-2004-0112 24 4d, Apple, Avaya and 21 more 65 Webstar, Mac Os X, Mac Os X Server and 62 more 2026-04-16 N/A
The SSL/TLS handshaking code in OpenSSL 0.9.7a, 0.9.7b, and 0.9.7c, when using Kerberos ciphersuites, does not properly check the length of Kerberos tickets during a handshake, which allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that causes an out-of-bounds read.
CVE-1999-0157 1 Cisco 2 Ios, Pix Firewall Software 2026-04-16 N/A
Cisco PIX firewall and CBAC IP fragmentation attack results in a denial of service.
CVE-2001-1434 1 Cisco 1 Ios 2026-04-16 N/A
Cisco IOS 12.0(5)XU through 12.1(2) allows remote attackers to read system administration and topology information via an "snmp-server host" command, which creates a readable "community" community string if one has not been previously created.
CVE-2006-4774 1 Cisco 1 Ios 2026-04-16 N/A
The VLAN Trunking Protocol (VTP) feature in Cisco IOS 12.1(19) allows remote attackers to cause a denial of service by sending a VTP version 1 summary frame with a VTP version field value of 2.
CVE-1999-0293 1 Cisco 1 Ios 2026-04-16 N/A
AAA authentication on Cisco systems allows attackers to execute commands without authorization.
CVE-2002-1357 7 Cisco, Fissh, Intersoft and 4 more 7 Ios, Ssh Client, Securenetterm and 4 more 2026-04-16 N/A
Multiple SSH2 servers and clients do not properly handle packets or data elements with incorrect length specifiers, 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.
