Wind River has released a security advisory pertaining to their embedded version of Linux. This advisory contains vulnerabilities that may affect Avaya systems.
The TLS protocol 1.1 and 1.2 and the DTLS protocol 1.0 and 1.2, as used in OpenSSL, OpenJDK, PolarSSL, and other products, do not properly consider timing side-channel attacks on a MAC check requirement during the processing of malformed CBC padding, which allows remote attackers to conduct distinguishing attacks and plaintext-recovery attacks via statistical analysis of timing data for crafted packets, aka the "Lucky Thirteen" issue. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2013-0169 to this issue.
More information about this vulnerability can be found in the security advisory issued by Wind River (A login is required):
|Product:||Affected Version(s):||Risk Level:||Actions:|
|Avaya 96x1 IP Deskphones||6.0 thru 6.6||Low||For SIP, upgrade to 7.0 or later.
For H.323 and B189, upgrade to 6.6.1 or later.
Recommended Actions for System Products:
Avaya strongly recommends following the 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 the System Product operating system or application should not be modified 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:
||The risk is rated Low because TLS 1.1 or 1.2 is not used by 96x1 IP Deskphones.|
