15 Synopsis
16 ========
17
18 Multiple vulnerabilities in gdk-pixbuf may create a Denial of Service
19 condition.
20
21 Background
22 ==========
23
24 gdk-pixbuf is an image loading library for GTK+.
25
26 Affected packages
27 =================
28
29 -------------------------------------------------------------------
30 Package / Vulnerable / Unaffected
31 -------------------------------------------------------------------
32 1 x11-libs/gdk-pixbuf < 2.24.1-r1 >= 2.24.1-r1
33
34 Description
35 ===========
36
37 Two vulnerabilities have been found in gdk-pixbuf:
38
39 * The "gdk_pixbuf__gif_image_load()" function in io-gif.c fails to
40 properly handle certain return values from subroutines
41 (CVE-2011-2485).
42 * The "read_bitmap_file_data()" function in io-xbm.c contains an
43 integer overflow error (CVE-2012-2370).
44
45 Impact
46 ======
47
48 A remote attacker could entice a user to open a specially crafted image
49 in an application linked against gdk-pixbuf, possibly resulting in
50 Denial of Service.
51
52 Workaround
53 ==========
54
55 There is no known workaround at this time.
56
57 Resolution
58 ==========
59
60 All gdk-pixbuf users should upgrade to the latest version:
61
62 # emerge --sync
63 # emerge --ask --oneshot --verbose ">=x11-libs/gdk-pixbuf-2.24.1-r1"
64
65 Packages which depend on this library may need to be recompiled. Tools
66 such as revdep-rebuild may assist in identifying some of these
67 packages.
