CVE-2004-0054 1 Cisco 1 Ios 2024-02-04 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-1999-1465 1 Cisco 1 Ios 2024-02-04 7.5 HIGH N/A
Vulnerability in Cisco IOS 11.1 through 11.3 with distributed fast switching (DFS) enabled allows remote attackers to bypass certain access control lists when the router switches traffic from a DFS-enabled input interface to an output interface with a logical subinterface, as described by Cisco bug CSCdk43862.
CVE-1999-0524 9 Apple, Cisco, Hp and 6 more 12 Mac Os X, Macos, Ios and 9 more 2024-02-04 2.1 LOW N/A
ICMP information such as (1) netmask and (2) timestamp is allowed from arbitrary hosts.
CVE-2000-0700 1 Cisco 4 Gigabit Switch Router 12008, Gigabit Switch Router 12012, Gigabit Switch Router 12016 and 1 more 2024-02-04 5.0 MEDIUM N/A
Cisco Gigabit Switch Routers (GSR) with Fast Ethernet / Gigabit Ethernet cards, from IOS versions 11.2(15)GS1A up to 11.2(19)GS0.2 and some versions of 12.0, do not properly handle line card failures, which allows remote attackers to bypass ACLs or force the interface to stop forwarding packets.
CVE-1999-0016 6 Cisco, Gnu, Hp and 3 more 8 Ios, Inet, Hp-ux and 5 more 2024-02-04 5.0 MEDIUM N/A
Land IP denial of service.
CVE-2004-0714 1 Cisco 3 Ios, Ons 15454e Optical Transport Platform, Optical Networking Systems Software 2024-02-04 5.0 MEDIUM N/A
Cisco Internetwork Operating System (IOS) 12.0S through 12.3T attempts to process SNMP solicited operations on improper ports (UDP 162 and a randomly chosen UDP port), which allows remote attackers to cause a denial of service (device reload and memory corruption).
CVE-2004-0081 23 4d, Apple, Avaya and 20 more 66 Webstar, Mac Os X, Mac Os X Server and 63 more 2024-02-04 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-2003-0851 2 Cisco, Openssl 5 Css11000 Content Services Switch, Ios, Pix Firewall and 2 more 2024-02-04 5.0 MEDIUM N/A
OpenSSL 0.9.6k allows remote attackers to cause a denial of service (crash via large recursion) via malformed ASN.1 sequences.
CVE-2003-0647 1 Cisco 1 Ios 2024-02-04 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-2002-1360 7 Cisco, Fissh, Intersoft and 4 more 7 Ios, Ssh Client, Securenetterm and 4 more 2024-02-04 10.0 HIGH 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.
CVE-2000-0345 1 Cisco 7 Ios, Router 2500, Router 2600 and 4 more 2024-02-04 2.1 LOW N/A
The on-line help system options in Cisco routers allows non-privileged users without "enabled" access to obtain sensitive information via the show command.
CVE-2004-0710 1 Cisco 1 Ios 2024-02-04 5.0 MEDIUM 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-2001-0650 1 Cisco 1 Ios 2024-02-04 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-2004-1454 1 Cisco 1 Ios 2024-02-04 5.0 MEDIUM N/A
Cisco IOS 12.0S, 12.2, and 12.3, with Open Shortest Path First (OSPF) enabled, allows remote attackers to cause a denial of service (device reload) via a malformed OSPF packet.
CVE-1999-0159 1 Cisco 1 Ios 2024-02-04 5.0 MEDIUM N/A
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-2004-1464 1 Cisco 1 Ios 2024-02-04 5.0 MEDIUM N/A
Cisco IOS 12.2(15) and earlier allows remote attackers to cause a denial of service (refused VTY (virtual terminal) connections), via a crafted TCP connection to the Telnet or reverse Telnet port.
CVE-1999-0445 1 Cisco 1 Ios 2024-02-04 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-2000-0984 1 Cisco 1 Ios 2024-02-04 5.0 MEDIUM 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-2003-0512 1 Cisco 1 Ios 2024-02-04 5.0 MEDIUM N/A
Cisco IOS 12.2 and earlier generates a "% Login invalid" message instead of prompting for a password when an invalid username is provided, which allows remote attackers to identify valid usernames on the system and conduct brute force password guessing, as reported for the Aironet Bridge.
CVE-2002-1358 7 Cisco, Fissh, Intersoft and 4 more 7 Ios, Ssh Client, Securenetterm and 4 more 2024-02-04 10.0 HIGH 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.
