18 A vulnerability in MAN DB allows local users to gain root privileges.
19
20 Background

33
34 Description
35 ===========
36
37 The /var/cache/man directory as part of the MAN DB package has group
38 permissions set to root.
39
40 Impact
41 ======
42
43 A local user who does not belong to the root group, but has the ability
44 to modify the /var/cache/man directory can escalate privileges to the
45 group root.

51
52 Resolution
53 ==========
