15 Synopsis
16 ========
17
18 An error in git-daemon might lead to a Denial of Service via resource
19 consumption.
20
21 Background
22 ==========
23
24 git - the stupid content tracker, the revision control system used by
25 the Linux kernel team.
26
27 Affected packages
28 =================
29
30 -------------------------------------------------------------------
31 Package / Vulnerable / Unaffected
32 -------------------------------------------------------------------
33 1 dev-util/git < 1.6.3.3 >= 1.6.3.3
34
35 Description
36 ===========
37
38 Shawn O. Pearce reported that git-daemon runs into an infinite loop
39 when handling requests that contain unrecognized arguments.
40
41 Impact
42 ======
43
44 A remote unauthenticated attacker could send a specially crafted
45 request to git-daemon, possibly leading to a Denial of Service (CPU
46 consumption).
47
48 Workaround
49 ==========
50
51 There is no known workaround at this time.
52
53 Resolution
54 ==========
55
56 All git users should upgrade to the latest version:
57
58 # emerge --sync
59 # emerge --ask --oneshot --verbose ">=dev-util/git-1.6.3.3"
