GNU Bash is a popular open source command line shell incorporated into Linux and other widely used operating systems. Vulnerabilities have been discovered that may allow a remote user to execute arbitrary code on systems that are running affected versions of Bash. These vulnerabilities are also known as shellshock. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2014-6271, CVE-2014-7169, CVE-2014-7186, CVE-2014-7187, CVE-2014-6277 and CVE-2014-6278 to these issues.
Product: | Affected Version(s): | Risk Level: | Actions: |
---|---|---|---|
EMS (Linux) | 6.x | High | Contact Avaya support for the necessary process to resolve this issue. |
EMS (Solaris) | None | None | See Mitigating Factors table below. |
G860 SC | None | None | See Mitigating Factors table below. |
M3000 | None | None | See Mitigating Factors table below. |
Recommended Actions for System Products:
Avaya strongly recommends following 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 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:
Vulnerability | Mitigating Factors |
---|---|
CVE-2014-6271 CVE-2014-7169 CVE-2014-7186 CVE-2014-7187 |
The risk is rated High for the EMS (Linux) because exploiting this vulnerability could bypass security restrictions and allow shell commands to be executed. There is no risk for the EMS (Solaris), G860SC and M3000 as bash is not installed. |
