CVE-2005-0195 1 Cisco 1 Ios 2026-04-16 N/A
Cisco IOS 12.0S through 12.3YH allows remote attackers to cause a denial of service (device restart) via a crafted IPv6 packet.
CVE-2005-4258 1 Cisco 71 Catalyst, Catalyst 1200 Series, Catalyst 1900 Series and 68 more 2026-04-16 N/A
Unspecified Cisco Catalyst Switches allow remote attackers to cause a denial of service (device crash) via an IP packet with the same source and destination IPs and ports, and with the SYN flag set (aka LanD). NOTE: the provenance of this issue is unknown; the details are obtained solely from the BID.
CVE-2004-0244 1 Cisco 1 Ios 2026-04-16 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-1999-0162 1 Cisco 1 Ios 2026-04-16 N/A
The "established" keyword in some Cisco IOS software allowed an attacker to bypass filtering.
CVE-2004-1111 1 Cisco 10 7200 Router, 7300 Router, 7500 Router and 7 more 2026-04-16 N/A
Cisco IOS 2.2(18)EW, 12.2(18)EWA, 12.2(14)SZ, 12.2(18)S, 12.2(18)SE, 12.2(18)SV, 12.2(18)SW, and other versions without the "no service dhcp" command, keep undeliverable DHCP packets in the queue instead of dropping them, which allows remote attackers to cause a denial of service (dropped traffic) via multiple undeliverable DHCP packets that exceed the input queue size.
CVE-2005-2105 1 Cisco 1 Ios 2026-04-16 N/A
Cisco IOS 12.2T through 12.4 allows remote attackers to bypass Authentication, Authorization, and Accounting (AAA) RADIUS authentication, if the fallback method is set to none, via a long username.
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-1999-0016 6 Cisco, Gnu, Hp and 3 more 8 Ios, Inet, Hp-ux and 5 more 2026-04-16 N/A
Land IP denial of service.
CVE-2005-1058 1 Cisco 1 Ios 2026-04-16 N/A
Cisco IOS 12.2T, 12.3 and 12.3T, when processing an ISAKMP profile that specifies XAUTH authentication after Phase 1 negotiation, may not process certain attributes in the ISAKMP profile that specifies XAUTH, which allows remote attackers to bypass XAUTH and move to Phase 2 negotiations.
CVE-2004-0081 23 4d, Apple, Avaya and 20 more 67 Webstar, Mac Os X, Mac Os X Server and 64 more 2026-04-16 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-2003-1398 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-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-2004-1454 1 Cisco 1 Ios 2026-04-16 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-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-2003-0851 3 Cisco, Openssl, Redhat 7 Css11000 Content Services Switch, Ios, Pix Firewall and 4 more 2026-04-16 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-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-1999-0063 1 Cisco 1 Ios 2026-04-16 N/A

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-2003-0647 1 Cisco 1 Ios 2026-04-16 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.
