The kernel packages contain the Linux kernel, the core of any Linux operating system.
A buffer overflow flaw was found in the way the qeth_snmp_command() function in the Linux kernel's QETH network device driver implementation handled SNMP IOCTL requests with an out-of-bounds length. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2013-6381 to this issue.
A flaw was found in the way the get_dumpable() function return value was interpreted in the ptrace subsystem of the Linux kernel. When 'fs.suid_dumpable' was set to 2, a local, unprivileged local user could use this flaw to bypass intended ptrace restrictions and obtain potentially sensitive information. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2013-2929 to this issue.
It was found that certain protocol handlers in the Linux kernel's networking implementation could set the addr_len value without initializing the associated data structure. A local, unprivileged user could use this flaw to leak kernel stack memory to user space using the recvmsg, recvfrom, and recvmmsg system calls. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2013-7263 and CVE-2013-7265 to these issues.

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:
| Vulnerability | Mitigating Factors |
|---|---|
|
CVE-2013-2929 |
This is a Low risk as the use of ptrace is restricted to privileged accounts. |
|
CVE-2013-6381 |
This is a Low risk for Collaboration Environment, Experience Portal and Session Manager as the qeth driver is not used by default. This is a Medium risk for CMS, IP Office Server, IP Office Application Server and One-X Client Enablement Services due to the potential for a user to cause a Denial of Service. |
|
CVE-2013-7263 CVE-2013-7265 |
These are a Low risk as exploitation would require privileged account access. |
Avaya software-only products operate on general-purpose operating systems. Occasionally vulnerabilities may be discovered in the underlying operating system or applications that come with the operating system. These vulnerabilities often do not impact the software-only product directly but may threaten the integrity of the underlying platform.
In the case of this advisory Avaya software-only products are not affected by the vulnerability directly but the underlying Linux platform may be. Customers should determine on which Linux operating system the product was installed and then follow that vendor's guidance.
| Product: | Actions: |
|---|---|
| Avaya Aura® Experience Portal | Depending on the Operating System installed, the affected package may be installed on the underlying Operating System supporting the EP application. |
Recommended Actions for Software-Only Products:
In the event that the affected package is installed, Avaya recommends following the recommended actions supplied by Red Hat regarding their Enterprise Linux.
Additional information may also be available via the Avaya support website and through your Avaya account representative. Please contact your Avaya product support representative, or dial 1-800-242-2121, with any questions.
