The Internet Key Exchange version 1 (IKEv1) implementation in Avaya VSU 100, 2000, 7500, 10000, and CSU 5000, when running IPSec, allows remote attackers to cause a denial of service (crash) via certain IKE packets, as demonstrated by the PROTOS ISAKMP Test Suite for IKEv1. NOTE: due to the lack of details in the advisory, it is unclear which of CVE-2005-3666, CVE-2005-3667, and/or CVE-2005-3668 this issue applies to.

POP3 service in Avaya Modular Messaging Message Storage Server (MSS) 2.0 SP 4 and earlier allows remote attackers to cause a denial of service (infinite loop) via crafted packets.

OpenSSL 0.9.6 before 0.9.6d does not properly handle unknown message types, which allows remote attackers to cause a denial of service (infinite loop), as demonstrated using the Codenomicon TLS Test Tool.

The SSL/TLS handshaking code in OpenSSL 0.9.7a, 0.9.7b, and 0.9.7c, when using Kerberos ciphersuites, does not properly check the length of Kerberos tickets during a handshake, which allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that causes an out-of-bounds read.

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.

Avaya Argent Office allows remote attackers to cause a denial of service by sending UDP packets to port 53 with no payload.

The Avaya 4602 SW IP Phone (Model 4602D02A) with 2.2.2 and earlier SIP firmware uses a constant media port number for calls, which allows remote attackers to cause a denial of service (audio quality loss) via a flood of packets to the RTP port.

A vulnerability in the "capro" (Call Processor) process component of Avaya Aura Communication Manager could allow a remote, unauthenticated user to cause denial of service. Affected versions include 6.3.x, all 7.x versions prior to 7.1.3.2, and all 8.x versions prior to 8.0.1.

A Null pointer dereference vulnerability exists in Mozilla Network Security Services due to a missing NULL check in PK11_SignWithSymKey / ssl3_ComputeRecordMACConstantTime, which could let a remote malicious user cause a Denial of Service.

Unspecified vulnerability in Avaya IP Softphone 6.0 SP4 and 6.01.85 allows remote attackers to cause a denial of service (crash) via a large amount of H.323 data.

Buffer overflow in the Session Initiation Protocol (SIP) User Access Client (UAC) message parsing module in Avaya one-X Desktop Edition 2.1.0.70 and earlier allows remote attackers to cause a denial of service (call reception outage) via a malformed SIP message.

The Avaya 4602 SW IP Phone (Model 4602D02A) with 2.2.2 and earlier SIP firmware allows remote attackers to cause a denial of service (device reboot) via a flood of packets to the BOOTP port (68/udp).

Microsoft Outlook Express 5.5 and 6 allows attackers to cause a denial of service (application crash) via a malformed e-mail header.
