Synopsis |
20 |
======== |
21 |
|
22 |
OpenSSL contains a vulnerability allowing execution of arbitrary code |
23 |
or a Denial of Service. |
24 |
|
25 |
Background |
26 |
========== |
27 |
|
28 |
OpenSSL is an Open Source toolkit implementing the Secure Sockets Layer |
29 |
(SSL v2/v3) and Transport Layer Security (TLS v1) as well as a general |
30 |
purpose cryptography library. |
31 |
|
32 |
Affected packages |
33 |
================= |

|

------------------------------------------------------------------- |
36 |
Package / Vulnerable / Unaffected |

Description |
41 |
=========== |
42 |
|
43 |
Andy Polyakov reported a vulnerability in the OpenSSL toolkit, that is |
44 |
caused due to an unspecified off-by-one error within the DTLS |
45 |
implementation. |
46 |
|
47 |
Impact |
48 |
====== |
49 |
|
50 |
A remote attacker could exploit this issue to execute arbitrary code or |
51 |
cause a Denial of Service. Only clients and servers explicitly using |
52 |
DTLS are affected, systems using SSL and TLS are not. |
53 |
|
54 |
Workaround |
55 |
========== |
56 |
|
57 |
There is no known workaround at this time. |
58 |
|
59 |
Resolution |
60 |
========== |
61 |
|
62 |
All OpenSSL users should upgrade to the latest version: |
63 |
|
64 |
# emerge --sync |
65 |
# emerge --ask --oneshot --verbose ">=dev-libs/openssl-0.9.8f" |
66 |
|
