A vulnerability in the Session Initiation Protocol (SIP) ingress packet processing of Cisco Unified IP Phone software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. The vulnerability is due to a lack of flow-control mechanisms in the software. An attacker could exploit this vulnerability by sending high volumes of SIP INVITE traffic to the targeted device. Successful exploitation could allow the attacker to cause a disruption of services on the targeted IP phone. Cisco Bug IDs: CSCve10064, CSCve14617, CSCve14638, CSCve14683, CSCve20812, CSCve20926, CSCve20945.

The encryption-processing feature in Cisco libSRTP before 1.5.3 allows remote attackers to cause a denial of service via crafted fields in SRTP packets, aka Bug ID CSCux00686.

Cisco 9900 Unified IP phones allow remote attackers to cause a denial of service (unregistration) via a crafted SIP header, aka Bug ID CSCul24898.

The firmware on Cisco Unified IP phones 8961, 9951, and 9971 uses weak permissions for memory block devices, which allows local users to gain privileges by mounting a device with a setuid file in its filesystem, aka Bug ID CSCui04382.

The image-upgrade functionality on Cisco 9900 Unified IP phones allows local users to gain privileges by placing shell commands in an unspecified parameter, aka Bug ID CSCuh10334.

Buffer overflow in the web-application interface on Cisco 9900 IP phones allows remote attackers to cause a denial of service (webapp interface outage) via long values in unspecified fields, aka Bug ID CSCuh10343.

The Cisco Unified IP Phone 8945 with software 9.3(2) allows remote attackers to cause a denial of service (device hang) via a malformed PNG file, aka Bug ID CSCud04270.

The Serviceability servlet on Cisco 9900 IP phones does not properly restrict paths, which allows remote attackers to read arbitrary files by specifying a pathname in a file request, aka Bug ID CSCuh52810.

Cisco Unified IP Phones 9900 series devices with firmware 9.1 and 9.2 do not properly handle downloads of configuration information to an RT phone, which allows local users to gain privileges via unspecified injected data, aka Bug ID CSCts32237.

The command line interface (CLI) in Cisco Unified IP Phone 7906G, 7911G, 7941G, 7961G, 7970G, and 7971G, with firmware 8.0(4)SR1 and earlier allows local users to obtain privileges or cause a denial of service via unspecified vectors. NOTE: this issue can be leveraged remotely via CVE-2007-1063.
