Synopsis |
16 |
======== |
17 |
|
18 |
Compress::Zlib is vulnerable to a buffer overflow which could |
19 |
potentially lead to execution of arbitrary code. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
The Compress::Zlib is a Perl module which provides an interface to the |
25 |
zlib compression library. |

Description |
36 |
=========== |
37 |
|
38 |
Compress::Zlib 1.34 contains a local vulnerable version of zlib, which |
39 |
may lead to a buffer overflow. |
40 |
|
41 |
Impact |
42 |
====== |
43 |
|
44 |
By creating a specially crafted compressed data stream, attackers can |
45 |
overwrite data structures for applications that use Compress::Zlib, |
46 |
resulting in a Denial of Service and potentially arbitrary code |
47 |
execution. |
48 |
|
49 |
Workaround |
50 |
========== |
51 |
|
52 |
There is no known workaround at this time. |
53 |
|
54 |
Resolution |
55 |
========== |
56 |
|
57 |
All Compress::Zlib users should upgrade to the latest version: |
58 |
|
59 |
# emerge --sync |
60 |
# emerge --ask --oneshot --verbose ">=dev-perl/Compress-Zlib-1.35" |
61 |
