15 Synopsis
16 ========
17
18 Multiple buffer overflow vulnerabilities in gdk-pixbuf may allow remote
19 attackers to execute arbitrary code or cause Denial of Service.
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 < 2.32.1 >= 2.32.1
33
34 Description
35 ===========
36
37 Three heap-based buffer overflow vulnerabilities have been discovered
38 in gdk-pixbuf. Please review the CVE identifiers referenced below for
39 details.
40
41 Impact
42 ======
43
44 A remote attacker could entice a user to open a specially crafted image
45 file with an application linked against gdk-pixbuf, possibly resulting
46 in execution of arbitrary code with the privileges of the process or a
47 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 gdk-pixbuf users should upgrade to the latest version:
58
59 # emerge --sync
60 # emerge --ask --oneshot --verbose ">=x11-libs/gdk-pixbuf-2.32.1"
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.
