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. |

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" |
