CVE-2005-3774 1 Cisco 1 Pix 2026-04-16 N/A
Cisco PIX 6.3 and 7.0 allows remote attackers to cause a denial of service (blocked new connections) via spoofed TCP packets that cause the PIX to create embryonic connections that that would not produce a valid connection with the end system, including (1) SYN packets with invalid checksums, which do not result in a RST; or, from an external interface, (2) one byte of "meaningless data," or (3) a TTL that is one less than needed to reach the internal destination.
CVE-2005-4825 1 Cisco 1 Network Admission Control Manager And Server System Software 2026-04-16 N/A
Cisco Clean Access 3.5.5 and earlier on the Secure Smart Manager allows remote attackers to bypass authentication and cause a denial of service (disk consumption), or make unauthorized files accessible, by uploading files through requests to certain JSP scripts, a related issue to CVE-2005-4332.
