15 Synopsis
16 ========
17
18 The JPEG library is vulnerable to a Denial of Service.
19
20 Background
21 ==========
22
23 The JPEG library is able to load, handle and manipulate images in the
24 JPEG format.
25
26 Affected packages
27 =================
28
29 -------------------------------------------------------------------
30 Package / Vulnerable / Unaffected
31 -------------------------------------------------------------------
32 1 media-libs/jpeg < 6b-r7 >= 6b-r7
33
34 Description
35 ===========
36
37 Tavis Ormandy of the Gentoo Linux Auditing Team discovered that the
38 vulnerable JPEG library ebuilds compile JPEG without the --maxmem
39 feature which is not recommended.
40
41 Impact
42 ======
43
44 By enticing a user to load a specially crafted JPEG image file an
45 attacker could cause a Denial of Service, due to memory exhaustion.
46
47 Workaround
48 ==========
49
50 There is no known workaround at this time.
51
52 Resolution
53 ==========
54
55 JPEG users should upgrade to the latest version:
56
57 # emerge --sync
58 # emerge --ask --oneshot --verbose ">=media-libs/jpeg-6b-r7"
