CVE-2009-2857
5.5 · MEDIUMOverview
CVE-2009-2857 is a medium-severity vulnerability affecting oracle opensolaris. It was published on August 19, 2009 and has a CVSS 3.1 base score of 5.5 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
The kernel in Sun Solaris 8, 9, and 10, and OpenSolaris before snv_103, does not properly handle interaction between the filesystem and virtual-memory implementations, which allows local users to cause a denial of service (deadlock and system halt) via vectors involving mmap and write operations on the same file.
Remediation
Check the references section for vendor advisories and patches from oracle. Update opensolaris to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
