Wind River has released a security advisory pertaining to their embedded version of Linux. This advisory contains vulnerabilities that may affect Avaya systems.
The ephemeral ECDH ciphersuite functionality in OpenSSL 0.9.8 through 0.9.8s and 1.0.x before 1.0.0e does not ensure thread safety during processing of handshake messages, which allows remote attackers to cause a denial of service (application crash) via out-of-order messages that violate the TLS protocol. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2011-3210 to this issue.
crypto/x509/x509_vfy.c in OpenSSL 1.0.x before 1.0.0e does not initialize certain structure members, which makes it easier for remote attackers to bypass CRL validation by using a nextUpdate value corresponding to a time in the past. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2011-3207 to this issue.
More information about these vulnerabilities can be found in the security advisories issued by Wind River (A login is required):
Product: | Affected Version(s): | Risk Level: | Actions: |
---|---|---|---|
Avaya 96x1 IP Deskphones | 6.0.x, 6.1.x, 6.2.x, 6.3 specifically for H.323 desk phones | Medium | For H.323 desk phones, upgrade to 6.3.1 or later. For SIP desk phones, upgrade to 6.3 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.
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:
Vulnerability | Mitigating Factors |
---|---|
CVE-2011-3210 CVE-2011-3207 |
These are a medium risk due to the potential for a Denial of Service (DoS). |
