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-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-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-2001-1105 2 Cisco, Dell 2 Icdn, Bsafe Ssl-j 2026-04-16 N/A
RSA BSAFE SSL-J 3.0, 3.0.1 and 3.1, as used in Cisco iCND 2.0, caches session IDs from failed login attempts, which could allow remote attackers to bypass SSL client authentication and gain access to sensitive data by logging in after an initial failure.
CVE-2006-3596 1 Cisco 1 Ips Sensor Software 2026-04-16 N/A
The device driver for Intel-based gigabit network adapters in Cisco Intrusion Prevention System (IPS) 5.1(1) through 5.1(p1), as installed on various Cisco Intrusion Prevention System 42xx appliances, allows remote attackers to cause a denial of service (kernel panic and possibly network outage) via a crafted IP packet.
