18 Synopsis
19 ========
20
21 T1Lib is vulnerable to a buffer overflow allowing for the user-assisted
22 execution of arbitrary code.
23
24 Background
25 ==========
26
27 T1Lib is a library for rasterizing bitmaps from Adobe Type 1 fonts.
28
29 Affected packages
30 =================
31
32 -------------------------------------------------------------------
33 Package / Vulnerable / Unaffected
34 -------------------------------------------------------------------
35 1 media-libs/t1lib < 5.0.2-r1 >= 5.0.2-r1
36
37 Description
38 ===========
39
40 Hamid Ebadi discovered a boundary error in the
41 intT1_EnvGetCompletePath() function which can lead to a buffer overflow
42 when processing an overly long filename.
43
44 Impact
45 ======
46
47 A remote attacker could entice a user to open a font file with a
48 specially crafted filename, possibly leading to the execution of
49 arbitrary code with the privileges of the user running the application
50 using T1Lib.
51
52 Workaround
53 ==========
54
55 There is no known workaround at this time.
56
57 Resolution
58 ==========
59
60 All T1Lib users should upgrade to the latest version:
61
62 # emerge --sync
63 # emerge --ask --oneshot --verbose ">=media-libs/t1lib-5.0.2-r1"
