The kernel packages contain the Linux kernel, the core of any Linux operating system.
A flaw was found in the way the Linux kernel's floppy driver handled user space provided data in certain error code paths while processing FDRAWCMD IOCTL commands. A local user with write access to /dev/fdX could use this flaw to free (using the kfree() function) arbitrary kernel memory. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2014-1737 to this issue.
It was found that the Linux kernel's floppy driver leaked internal kernel memory addresses to user space during the processing of the FDRAWCMD IOCTL command. A local user with write access to /dev/fdX could use this flaw to obtain information about the kernel heap arrangement. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2014-1738 to this issue.
Note: A local user with write access to /dev/fdX could use these two flaws The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2014-1737 in combination with CVE-2014-1738 to this issue. to escalate their privileges on the system.
A NULL pointer dereference flaw was found in the rds_ib_laddr_check() function in the Linux kernel's implementation of Reliable Datagram Sockets (RDS). A local, unprivileged user could use this flaw to crash the system. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2013-7339 to this issue.

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 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-2014-1737 CVE-2014-1738 |
There is no risk to all products listed as Avaya common servers do not have a floppy disk drive. |
CVE-2013-7339 | This is a Low risk to all products listed as Reliable Datagram Sockets are not used or supported. |
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.
