Synopsis |
17 |
======== |
18 |
|
19 |
A buffer overflow in International Components for Unicode could result |
20 |
in execution of arbitrary code or Denial of Service. |
21 |
|
22 |
Background |
23 |
========== |
24 |
|
25 |
International Components for Unicode (ICU) is a set of C/C++ and Java |
26 |
libraries providing Unicode and Globalization support for software |
27 |
applications. |
28 |
|
29 |
Affected packages |
30 |
================= |
31 |
|
32 |
------------------------------------------------------------------- |
33 |
Package / Vulnerable / Unaffected |
34 |
------------------------------------------------------------------- |
35 |

36 |
|
37 |
Description |
38 |
=========== |
39 |
|
40 |
An error in the _canonicalize() function in uloc.cpp could cause a |
41 |
stack-based buffer overflow. |
42 |
|
43 |
Impact |
44 |
====== |
45 |
|
46 |
A remote attacker could entice a user to open a specially crafted |
47 |
locale representation using an application linked against ICU, possibly |
48 |
resulting in execution of arbitrary code with the privileges of the |
49 |
process or a Denial of Service condition. |
50 |
|
51 |
Workaround |
52 |
========== |
53 |
|
54 |
There is no known workaround at this time. |
55 |
|
56 |
Resolution |
57 |
========== |
58 |
|
59 |
All ICU users should upgrade to the latest version: |
60 |
|
61 |
# emerge --sync |
62 |
# emerge --ask --oneshot --verbose ">=dev-libs/icu-49.1.1-r1" |
