New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

SynopsisThe remote Red Hat host is missing one or more security updates.
DescriptionUpdated kernel packages that fix a number of security issues are now available for Red Hat Enterprise Linux 2.1 running on 32-bit architectures.
This update has been rated as having important security impact by the Red Hat Security Response Team.
The kernel packages contain the Linux kernel, the core of any Linux operating system.
These updated packages fix the following security issues :
* a flaw was found in the IPv4 forwarding base. This could allow a local, unprivileged user to cause a denial of service. (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 depends 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 denial of service. (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. (CVE-2008-2136, Important)
* missing capability checks were found in the SBNI WAN driver which could allow a local, unprivileged user to bypass intended capability restrictions. (CVE-2008-3525, Important)
* 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. (CVE-2008-4210, Important)
* a race condition in the mincore system core allowed a local, unprivileged user to cause a denial of service. (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. (CVE-2007-4308, Moderate)
* 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. (CVE-2007-6063, CVE-2007-6151, Moderate)
* 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.
* 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 denial of service. (CVE-2008-3275, Moderate)
All users of Red Hat Enterprise Linux 2.1 on 32-bit architectures should upgrade to these updated packages which address these vulnerabilities. For this update to take effect, the system must be rebooted.
