The kernel-rt packages contain the Linux kernel, the core of any Linux operating system.
A denial of service flaw was found in the way the Linux kernel's XFS file system implementation ordered directory hashes under certain conditions. A local attacker could use this flaw to corrupt the file system by creating directories with colliding hash values, potentially resulting in a system crash. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2014-7283 to this issue.
An out-of-bounds memory access flaw was found in the syscall tracing functionality of the Linux kernel's perf subsystem. 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-2014-7825 to this issue.
An out-of-bounds memory access flaw was found in the syscall tracing functionality of the Linux kernel's ftrace subsystem. On a system with ftrace syscall tracing enabled, a local, unprivileged user could use this flaw to crash the system, or escalate their privileges. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2014-7826 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.
| Product: | Actions: |
