34 Description
35 ===========
36
37 It was discovered that Gentoo’s BURP ebuild does not properly set
38 permissions or place the pid file in a safe directory. Additionally,
39 the first set of patches did not completely address this. As such, a
40 revision has been made available that addresses all concerns of the
41 initial report.

43 Impact
44 ======
45
46 A local attacker could escalate privileges.
47
48 Workaround
49 ==========
50
51 Users should ensure the proper permissions are set as discussed in the
52 referenced bugs.
53
54 Resolution
55 ==========
56
57 All BURP users should upgrade to the latest version:
58
59 # emerge --sync
60 # emerge --ask --oneshot --verbose ">=app-backup/burp-2.1.32-r1"
