Security fixes:
SG_IO ioctl SCSI requests on partitions or LVM volumes could be passed to the underlying block device, allowing a privileged user to bypass restrictions and gain read and write access (and be able to issue other SCSI commands) to the entire block device. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2011-4127 to this issue.
A local, unprivileged user could use an integer overflow flaw in drm_mode_dirtyfb_ioctl() to cause a denial of service or escalate their privileges. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2012-0044 to this issue.
A local, unprivileged user could use a flaw in the Performance Events implementation to cause a denial of service. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2011-2918 to this issue.
A local, unprivileged user could use flaws in the XFS file system implementation to cause a denial of service or escalate their privileges by mounting a specially-crafted disk. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2011-4077 and CVE-2012-0038 to these issues.
A local, unprivileged user could use a flaw in the Out of Memory (OOM) killer to monopolize memory, have their process skipped by the OOM killer, or cause other tasks to be terminated. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2011-4097 to this issue.
A local, unprivileged user could use a flaw in the key management facility to cause a denial of service. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2011-4110 to this issue.
A malicious Network File System version 4 (NFSv4) server could return a crafted reply to a GETACL request, causing a denial of service on the client. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2011-4131 to this issue.
A local attacker could use a flaw in the Journaling Block Device (JBD) to crash the system by mounting a specially-crafted ext3 or ext4 disk. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2011-4132 to this issue.
A flaw in igmp_heard_query() could allow an attacker, who is able to send certain IGMP (Internet Group Management Protocol) packets to a target system, to cause a denial of service. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2012-0207 to this issue.
If lock contention during signal sending occurred when in a software interrupt handler that is using the per-CPU debug stack, the task could be scheduled out on the realtime kernel, possibly leading to debug stack corruption. A local, unprivileged user could use this flaw to cause a denial of service. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2012-0810 to this issue.
No Avaya system products are vulnerable, as the affected versions of kernel-rt are not installed by default.
More information about these vulnerabilities can be found in the security advisory issued by Red Hat:
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.
