2007-10-23 CVE-2007-5640 Remote Denial of Service vulnerability in Nortel UNIStim IP Phone
The Nortel UNIStim IP Softphone 2050, IP Phone 1140E, and additional Nortel products from the IP Phone, Business Communications Manager (BCM), Mobile Voice Client, and other product lines, allow remote attackers to block calls and force re-registration via a resume message to the Signaling Server that has a spoofed source IP address for the phone.

2007-10-23 CVE-2007-5638 Information Exposure vulnerability in Nortel products
The Nortel UNIStim IP Softphone 2050, IP Phone 1140E, and additional Nortel products from the IP Phone, Business Communications Manager (BCM), and other product lines, use only 65536 different values in the 32-bit ID number field of an RUDP datagram, which makes it easier for remote attackers to guess the RUDP ID and spoof messages.

2007-10-23 CVE-2007-5637 Information Exposure vulnerability in Nortel products
The Nortel UNIStim IP Softphone 2050, IP Phone 1140E, and additional Nortel products from the IP Phone, Business Communications Manager (BCM), and other product lines allow remote attackers to eavesdrop on the physical environment via an Open Audio Stream message that enables "surveillance mode." NOTE: issues relating to a small ID number space can be leveraged to make this attack easier.

2005-05-31 CVE-2005-0356 Remote Denial Of Service vulnerability in Multiple Vendor TCP Timestamp PAWS
Multiple TCP implementations with Protection Against Wrapped Sequence Numbers (PAWS) with the timestamps option enabled allow remote attackers to cause a denial of service (connection loss) via a spoofed packet with a large timer value, which causes the host to discard later packets because they appear to be too old.

2004-02-17 CVE-2004-0056 Unspecified vulnerability in Nortel products
Multiple vulnerabilities in the H.323 protocol implementation for Nortel Networks Business Communications Manager (BCM), Succession 1000 IP Trunk and IP Peer Networking, and 802.11 Wireless IP Gateway allow remote attackers to cause a denial of service and possibly execute arbitrary code, as demonstrated by the NISCC/OUSPG PROTOS test suite for the H.225 protocol.
