15 Synopsis
16 ========
17
18 Multiple buffer overflow flaws and a parser error in LittleCMS could
19 cause Denial of Service.
20
21 Background
22 ==========
23
24 LittleCMS, or short lcms, is a color management system for working with
25 ICC profiles. It is used by many applications including GIMP and
26 Firefox.
27
28 Affected packages
29 =================
30
31 -------------------------------------------------------------------
32 Package / Vulnerable / Unaffected
33 -------------------------------------------------------------------
34 1 media-libs/lcms < 2.6-r1 >= 2.6-r1
35
36 Description
37 ===========
38
39 Multiple stack-based buffer overflows and a profile parser error have
40 been found in LittleCMS.
41
42 Impact
43 ======
44
45 A remote attacker could entice a user or automated system to open a
46 specially crafted file containing a malicious ICC profile, possibly
47 resulting in a Denial of Service condition.
48
49 Workaround
50 ==========
51
52 There is no known workaround at this time.
53
54 Resolution
55 ==========
56
57 All LittleCMS users should upgrade to the latest version:
58
59 # emerge --sync
60 # emerge --ask --oneshot --verbose ">=media-libs/lcms-2.6-r1"
61
62 Packages which depend on this library may need to be recompiled. Tools
63 such as revdep-rebuild may assist in identifying these packages.
64
65 NOTE: Gentoo has discontinued support for the LittleCMS 1.9 branch.
