| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2011-10-22 | CVE-2011-2058 | Improper Input Validation vulnerability in Cisco IOS The cat6000-dot1x component in Cisco IOS 12.2 before 12.2(33)SXI7 does not properly handle an external loop between a pair of dot1x enabled ports, which allows remote attackers to cause a denial of service (traffic storm) via unspecified vectors that trigger many unicast EAPoL Protocol Data Units (PDUs), aka Bug ID CSCtq36336. | 7.5 |
| 2011-10-22 | CVE-2011-2057 | Improper Input Validation vulnerability in Cisco IOS The cat6000-dot1x component in Cisco IOS 12.2 before 12.2(33)SXI7 does not properly handle (1) a loop between a dot1x enabled port and an open-authentication dot1x enabled port and (2) a loop between a dot1x enabled port and a non-dot1x port, which allows remote attackers to cause a denial of service (traffic storm) via unspecified vectors that trigger many Spanning Tree Protocol (STP) Bridge Protocol Data Unit (BPDU) frames, aka Bug ID CSCtq36327. | 7.5 |
| 2011-10-22 | CVE-2011-1640 | Resource Exhaustion vulnerability in Cisco IOS The ethernet-lldp component in Cisco IOS 12.2 before 12.2(33)SXJ1 does not properly support a large number of LLDP Management Address (MA) TLVs, which allows remote attackers to cause a denial of service (device crash) via crafted LLDPDUs, aka Bug ID CSCtj22354. | 7.5 |
| 2011-10-03 | CVE-2011-3280 | Resource Management Errors vulnerability in Cisco IOS and IOS XE Memory leak in the NAT implementation in Cisco IOS 12.1 through 12.4 and 15.0 through 15.1, and IOS XE 3.1.xSG, allows remote attackers to cause a denial of service (memory consumption or device reload) by sending crafted SIP packets to UDP port 5060, aka Bug ID CSCtj04672. | 7.5 |
| 2004-12-31 | CVE-2004-1464 | Unspecified vulnerability in Cisco IOS 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. | 5.9 |
| 2004-11-23 | CVE-2004-0079 | NULL Pointer Dereference vulnerability in multiple products The do_change_cipher_spec function in OpenSSL 0.9.6c to 0.9.6k, and 0.9.7a to 0.9.7c, allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that triggers a null dereference. | 7.5 |
| 2002-12-31 | CVE-2002-1706 | Improper Verification of Cryptographic Signature vulnerability in Cisco IOS Cisco IOS software 11.3 through 12.2 running on Cisco uBR7200 and uBR7100 series Universal Broadband Routers allows remote attackers to modify Data Over Cable Service Interface Specification (DOCSIS) settings via a DOCSIS file without a Message Integrity Check (MIC) signature, which is approved by the router. | 7.5 |
