CWE Code: 264
Vulnerability Type: privilege_escalation
CVSS Score: 6.9
CWE Name:  Permissions Privileges and Access Controls
Summary: 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.
Access Authentication: NONE
Access Complexity: MEDIUM
Access Vector: LOCAL
Impact (C/I/A): COMPLETE/COMPLETE/COMPLETE
