CVE-2013-2171
6.9 · MEDIUMOverview
CVE-2013-2171 is a medium-severity vulnerability affecting freebsd freebsd. It was published on July 2, 2013 and has a CVSS 2.0 base score of 6.9 (MEDIUM).
This vulnerability has a CVSS 2.0 base score of 6.9, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical Description
The vm_map_lookup function in sys/vm/vm_map.c in the mmap implementation in the kernel in FreeBSD 9.0 through 9.1-RELEASE-p4 does not properly determine whether a task should have write access to a memory location, which allows local users to bypass filesystem write permissions and consequently gain privileges via a crafted application that leverages read permissions, and makes mmap and ptrace system calls.
Remediation
Check the references section for vendor advisories and patches from freebsd. Update freebsd 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.
