The kernel packages contain the Linux kernel, the core of any Linux operating system.
A flaw was found in the way the Linux kernel handled the creation of temporary IPv6 addresses. If the IPv6 privacy extension was enabled (/proc/sys/net/ipv6/conf/eth0/use_tempaddr is set to '2'), an attacker on the local network could disable IPv6 temporary address generation, leading to a potential information disclosure. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2013-0343 to this issue.
An information leak flaw was found in the way Linux kernel's device mapper subsystem, under certain conditions, interpreted data written to snapshot block devices. An attacker could use this flaw to read data from disk blocks in free space, which are normally inaccessible. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2013-4299 to this issue.
An off-by-one flaw was found in the way the ANSI CPRNG implementation in the Linux kernel processed non-block size aligned requests. This could lead to random numbers being generated with less bits of entropy than expected when ANSI CPRNG was used. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2013-4345 to this issue.
An information leak flaw was found in the way Xen hypervisor emulated the OUTS instruction for 64-bit paravirtualized guests. A privileged guest user could use this flaw to leak hypervisor stack memory to the guest. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2013-4368 to this issue.

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:
||This is a Low risk for all products as the privacy extension is not enabled by default.|
|These are a Low risk for all products as privileged account access would be required.|
||This is a Low risk for System Platform as privileged account access would be required.
There is no risk to other listed products as they do not host guests.
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.
