15 Synopsis
16 ========
17
18 An integer overflow in libXpm might allow remote attackers to execute
19 arbitrary code or cause a Denial of Service Condition.
20
21 Background
22 ==========
23
24 The X PixMap image format is an extension of the monochrome X BitMap
25 format specified in the X protocol, and is commonly used in traditional
26 X applications.
27
28 Affected packages
29 =================
30
31 -------------------------------------------------------------------
32 Package / Vulnerable / Unaffected
33 -------------------------------------------------------------------
34 1 x11-libs/libXpm < 3.5.12 >= 3.5.12
35
36 Description
37 ===========
38
39 An integer overflow was discovered in libXpm's src/CrDatFrI.c file. On
40 64 bit systems, this allows an overflow to occur on 32 bit integers
41 while parsing XPM extensions in a file.
42
43 Impact
44 ======
45
46 A remote attacker, by enticing a user to process a specially crafted
47 XPM file, could execute arbitrary code with the privileges of the
48 process or cause a Denial of Service condition.
49
50 Workaround
51 ==========
52
53 There is no known workaround at this time.
54
55 Resolution
56 ==========
57
58 All libXpm users should upgrade to the latest version:
59
60 # emerge --sync
61 # emerge --ask --oneshot --verbose ">=x11-libs/libXpm-3.5.12"
