Integer overflow in Cisco IOS allows remote attackers to execute arbitrary code via unspecified vectors. NOTE: as of 20071016, the only disclosure is a vague pre-advisory with no actionable information. However, since it is from a well-known researcher, it is being assigned a CVE identifier for tracking purposes.

Stack-based buffer overflow in the Line Printer Daemon (LPD) in Cisco IOS before 12.2(18)SXF11, 12.4(16a), and 12.4(2)T6 allow remote attackers to execute arbitrary code by setting a long hostname on the target system, then causing an error message to be printed, as demonstrated by a telnet session to the LPD from a source port other than 515.

The ATOMIC.TCP signature engine in the Intrusion Prevention System (IPS) feature for Cisco IOS 12.4XA, 12.3YA, 12.3T, and other trains allows remote attackers to cause a denial of service (IPS crash and traffic loss) via unspecified manipulations that are not properly handled by the regular expression feature, as demonstrated using the 3123.0 (Netbus Pro Traffic) signature.

Cisco IOS 12.2 through 12.4 before 20060920, as used by Cisco IAD2430, IAD2431, and IAD2432 Integrated Access Devices, the VG224 Analog Phone Gateway, and the MWR 1900 and 1941 Mobile Wireless Edge Routers, is incorrectly identified as supporting DOCSIS, which allows remote attackers to gain read-write access via a hard-coded cable-docsis community string and read or modify arbitrary SNMP variables.

Internet Key Exchange (IKE) version 1 protocol, as implemented on Cisco IOS, VPN 3000 Concentrators, and PIX firewalls, allows remote attackers to cause a denial of service (resource exhaustion) via a flood of IKE Phase-1 packets that exceed the session expiration rate. NOTE: it has been argued that this is due to a design weakness of the IKE version 1 protocol, in which case other vendors and implementations would also be affected.

Certain Cisco IOS releases in 12.2S based trains with maintenance release number 25 and later, 12.3T based trains, and 12.4 based trains reuse a Tcl Shell process across login sessions of different local users on the same terminal if the first user does not use tclquit before exiting, which may cause subsequent local users to execute unintended commands or bypass AAA command authorization checks, aka Bug ID CSCef77770.
