Title: Multiple Vendor BSD /proc File Sytem Vulnerability
Severity: MODERATE
Description:
Certain BSD derivative operating systems use an implantation of the /proc filesystem which is vulnerable to attack from malicious local users. This attack will gain the user root access to the host.
The proc file system was originally designed to allow easy access to information about processes (hence the name). Its typical benefit is quicker access to memory hence more streamlined operations. As noted previously
certain implementations have a serious vulnerability. In short, the vulnerability is that users may manipulate processes under system which use /proc to gain root privileges. The full details are covered at length in the advisory attached to the 'Credit' section of this vulnerability entry.
