CWE Code: 22
Vulnerability Type: privilege_escalation
CVSS Score: 4.6
CWE Name:  Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Summary: in freebsd 10.x before 10.4-stable, 10.4-release-p3, and 10.3-release-p24 named paths are globally scoped, meaning a process located in one jail can read and modify the content of posix shared memory objects created by a process in another jail or the host system. as a result, a malicious user that has access to a jailed system is able to abuse shared memory by injecting malicious content in the shared memory region. this memory region might be executed by applications trusting the shared memory, like squid. this issue could lead to a denial of service or local privilege escalation.
Access Authentication: NONE
Access Complexity: LOW
Access Vector: LOCAL
Impact (C/I/A): PARTIAL/PARTIAL/PARTIAL
