The kernel packages contain the Linux kernel, the core of any Linux operating system.
This update fixes the following security issues:
* an array index error was found in the gdth driver in the Linux kernel. A local user could send a specially-crafted IOCTL request that would cause a denial of service or, possibly, privilege escalation. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-3080 to this issue.
* a flaw was found in the collect_rx_frame() function in the HiSax ISDN driver (hfc_usb) in the Linux kernel. An attacker could use this flaw to send a specially-crafted HDLC packet that could trigger a buffer out of bounds, possibly resulting in a denial of service. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-4005 to this issue.
* permission issues were found in the megaraid_sas driver (for SAS based RAID controllers) in the Linux kernel. The "dbg_lvl" and "poll_mode_io" files on the sysfs file system ("/sys/") had world-writable permissions. This could allow local, unprivileged users to change the behavior of the driver. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2009-3889 and CVE-2009-3939 to these issues.
* a buffer overflow flaw was found in the hfs_bnode_read() function in the HFS file system implementation in the Linux kernel. This could lead to a denial of service if a user browsed a specially-crafted HFS file system, for example, by running "ls". The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-4020 to this issue.

Recommended Actions for System Products:
Avaya strongly recommends that customers follow
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's
product and the surrounding network from this potential
vulnerability may be mitigated by ensuring these
practices are implemented until such time as a product
update is available or the recommended action is applied.
Further restrictions as deemed necessary based on the
customer's security policies may be required during this
interim period.
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.
