1. Overview:

Wind River has released a security advisory pertaining to their embedded version of Linux. This advisory contains vulnerabilities that may affect Avaya systems. The following vulnerabilities are outlined by the Wind River security advisory:

• The ext4_decode_error function in the ext4 filesystem in the Linux kernel could allow remote attackers to cause a denial of service with local user interaction. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-4308 to this issue.
• The e1000 driver in the Linux kernel 2.6.32.3 and earlier handles Ethernet frames that exceed the MTU by processing certain trailing payload data as if it were a complete frame which could allow a remote attackers to bypass packet filters via a large packet with a crafted payload. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-4536 to this issue.
• The e1000e driver in the Linux kernel 2.6.32.3 and earlier does not properly check the size of an Ethernet frame that exceeds the MTU, which could allow a remote attacker to have an unspecified impact with a crafted packet. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-4538 to this issue.
• The ipv6_hop_jumbo function in the Linux kernel before 2.6.32.4 when network namespaces are enabled could allow remote attackers to cause a denial of service with an invalid IPv6 jumbogram. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-0006 to this issue.
• The Linux kernel 2.6.18 through 2.6.33 could allow remote attackers to cause a denial of service by openning a large number of Bluetooth sockets. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-1084 to this issue.
• The nfs_wait_on_request function in Linux kernel 2.6.x through 2.6.33-rc5 could allow attackers to cause a denial of service via unknown vectors related to truncating a file and an operation that is not interruptible. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-1087 to this issue.
• The NFS client file system in Linux kernel 2.6.18 through 2.6.34 does not always follow NFS automount "symlinks," which could allow an attacker to have an unknown impact, related to LOOKUP_FOLLOW. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-1088 to this issue.

2. Avaya System Products using Wind River Linux with affected components/packages installed:

Product:	Affected Version(s):	Risk Level:	Actions:
Avaya Desktop Video Device	1.0	Medium	Upgrade to Avaya Desktop Video Device with Avaya Flare® Experience Release 1.1 or later.

Recommended Actions for System Products:
Avaya strongly recommends that customers follow networking and security best practices by implementing firewalls, ACLs, physical security or other appropriate access restrictions. Though Avaya believes such restrictions should always be in place, risk to Avaya products and the surrounding network from this potential vulnerability may be mitigated by ensuring these practices are implemented until such time as an Avaya provided product update or the recommended Avaya action is applied. Further restrictions as deemed necessary based on the customer's security policies may be required during this interim period, but customers should not modify the System Product operating system or application unless the change is approved by Avaya. Making changes that are not approved may void the Avaya product service contract.

Mitigating Factors:

When determining risk, Avaya takes into account many factors as outlined by Avaya's Security Vulnerability Classification Policy. The following table describes factors that mitigate the risk of specific vulnerabilities for affected Avaya products:
