Cisco IOS Software contains a memory leak vulnerability in the Data-Link Switching (DLSw) feature that could result in a device reload when processing crafted IP Protocol 91 packets.

The Cisco IOS Software network address translation (NAT) feature contains multiple denial of service (DoS) vulnerabilities in the translation of the following protocols: NetMeeting Directory (Lightweight Directory Access Protocol, LDAP); Session Initiation Protocol (Multiple vulnerabilities); H.323 protocol

A denial of service (DoS) vulnerability exists in Jabber Extensible Communications Platform (Jabber XCP) and Cisco Unified Presence. An unauthenticated, remote attacker could exploit this vulnerability by sending malicious XML to an affected server. Successful exploitation of this vulnerability could cause elevated memory and CPU utilization, resulting in memory exhaustion and process crashes. Repeated exploitation could result in a sustained DoS condition.

Cisco Unified Communications Manager contains a memory leak vulnerability that could be triggered through the processing of malformed Session Initiation Protocol (SIP) messages. Exploitation of this vulnerability could cause an interruption of voice services. Cisco has released free software updates for supported Cisco Unified Communications Manager versions to address the vulnerability. A workaround exists for this SIP vulnerability.

Two vulnerabilities exist in CiscoWorks LAN Management Solution software that could allow an unauthenticated, remote attacker to execute arbitrary code on affected servers.

Two vulnerabilities exist in Cisco Unified Service Monitor and Cisco Unified Operations Manager software that could allow an unauthenticated, remote attacker to execute arbitrary code on affected servers.

The Apache HTTPd server contains a denial of service vulnerability when it handles multiple, overlapping ranges. Multiple Cisco products may be affected by this vulnerability.

A vulnerability exists in Cisco Nexus 5000 and 3000 Series Switches that may allow traffic to bypass deny statements in access control lists (ACLs) that are configured on the device.

Cisco TelePresence C Series Endpoints, E/EX Personal Video units, and MXP Series Codecs that are running software versions prior to TC4.0.0 or F9.1 contain a vulnerability that could allow an attacker to cause a denial of service.

Cisco Unified Communications Manager (previously known as Cisco CallManager) and Cisco Unified Presence Server contain an open query interface that could allow an unauthenticated, remote attacker to disclose the contents of the underlying databases on affected product versions.
