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.
VPR Score: 3.6
SynopsisThe remote CentOS host is missing one or more security updates.
DescriptionUpdated kernel packages that fix several security issues and a bug in the Red Hat Enterprise Linux 3 kernel are now available.
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.
A flaw was found in the handling of process death signals. This allowed a local user to send arbitrary signals to the suid-process executed by that user. A successful exploitation of this flaw depends on the structure of the suid-program and its signal handling.
A flaw was found in the IPv4 forwarding base. This allowed a local user to cause a denial of service. (CVE-2007-2172, Important)
A flaw was found where a corrupted executable file could cause cross-region memory mappings on Itanium systems. This allowed a local user to cause a denial of service. (CVE-2006-4538, Moderate)
A flaw was found in the stack expansion when using the hugetlb kernel on PowerPC systems. This allowed a local user to cause a denial of service. (CVE-2007-3739, Moderate)
A flaw was found in the aacraid SCSI driver. This allowed a local user to make ioctl calls to the driver that should be restricted to privileged users. (CVE-2007-4308, Moderate)
As well, these updated packages fix the following bug :
* a bug in the TCP header prediction code may have caused 'TCP:
Treason uncloaked!' messages to be logged. In certain situations this may have lead to TCP connections hanging or aborting.
Red Hat Enterprise Linux 3 users are advised to upgrade to these updated packages, which contain backported patches to resolve these issues.
SolutionUpdate the affected kernel packages.
