The kernel packages contain the Linux kernel, the core of any Linux operating system.
These updated packages for Red Hat Enterprise Linux 2.1 running on 64-bit architectures fix the following security issues:
* a flaw was found in the IPv4 forwarding base that allowed a local, unprivileged user to cause an out-of-bounds access. ( CVE-2007-2172, Important)
* a flaw was found in the handling of process death signals. This allowed a local, unprivileged user to send arbitrary signals to the suid-process executed by that user. Successful exploitation of this flaw depended on the structure of the suid-program and its signal handling. ( CVE-2007-3848, Important)
* when accessing kernel memory locations, certain Linux kernel drivers registering a fault handler did not perform required range checks. A local, unprivileged user could use this flaw to gain read or write access to arbitrary kernel memory, or possibly cause a kernel crash. ( CVE-2008-0007, Important)
* a possible kernel memory leak was found in the Linux kernel Simple Internet Transition (SIT) INET6 implementation. This could allow a local, unprivileged user to cause a denial of service. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2008-2136 to this issue.
* missing capability checks were found in the SBNI WAN driver which could allow a local, unprivileged user to bypass intended capability restrictions. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2008-3525 to this issue.
* a flaw was found in the way files were written using truncate() or ftruncate(). This could allow a local, unprivileged user to acquire the privileges of a different group and obtain access to sensitive information. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-200 8-4210 to this issue.
* a flaw was found in the ELF handling on Itanium-based systems. This triggered a cross-region memory-mapping and allowed a local, unprivileged user to cause a local denial of service. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2006-4538 to this issue.
* a race condition in the mincore system core allowed a local, unprivileged user to cause a local denial of service (system hang). ( CVE-2006-4814, Moderate)
* a flaw was found in the aacraid SCSI driver. This allowed a local, unprivileged user to make ioctl calls to the driver which should otherwise be restricted to privileged users. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2007-4308 to this issue.
* two buffer overflow flaws were found in the Integrated Services Digital Network (ISDN) subsystem. A local, unprivileged user could use these flaws to cause a denial of service. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2007-6063 and CVE-2007-6151 to these issues.
* a flaw was found in the way core dump files were created. If a local, unprivileged user could make a root-owned process dump a core file into a user-writable directory, the user could gain read access to that core file, potentially compromising sensitive information. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2007-6206 to this issue.
* a deficiency was found in the Linux kernel virtual file system (VFS) implementation. This could allow a local, unprivileged user to attempt file creation within deleted directories, possibly causing a local denial of service. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2008-3275 to this issue.
No Avaya system products are vulnerable, as Red Hat Enterprise Linux 2.1 running on 64-bit architectures is not installed by default.
More information about these vulnerabilities can be found in the security advisory issued by RedHat Linux:
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: |
|---|---|
| CVLAN | Depending on the Operating System provided by customers, the affected package may be installed on the underlying Operating System supporting the CVLAN application. |
| Avaya Integrated Management Suite (IMS) | Depending on the Operating System provided by customers, the affected package may be installed on the underlying Operating System supporting the IMS application. |
| Voice Portal | Depending on the Operating System provided by customers, the affected package may be installed on the underlying Operating System supporting the Voice Portal application. |
| AES 4.x | Depending on the Operating System provided by customers, the affected package may be installed on the underlying Operating System supporting the AES application. |
Recommended Actions:
In the event that the affected package
is installed, Avaya recommends that customers follow recommended actions
supplied by RedHat Linux.
