Synopsis |
16 |
======== |
17 |
|
18 |
The GnuTLS library is vulnerable to Denial of Service attacks. |
19 |
|
20 |
Background |
21 |
========== |
22 |
|
23 |
GnuTLS is a free TLS 1.0 and SSL 3.0 implementation for the GNU |
24 |
project. |
25 |
|
26 |
Affected packages |

Description |
36 |
=========== |
37 |
|
38 |
A vulnerability has been discovered in the record packet parsing in the |
39 |
GnuTLS library. Additionally, a flaw was also found in the RSA key |
40 |
export functionality. |
41 |
|
42 |
Impact |
43 |
====== |
44 |
|
45 |
A remote attacker could exploit this vulnerability and cause a Denial |
46 |
of Service to any application that utilizes the GnuTLS library. |
47 |
|
48 |
Workaround |
49 |
========== |
50 |
|
51 |
There is no known workaround at this time. |
52 |
|
53 |
Resolution |
54 |
========== |
55 |
|
56 |
All GnuTLS users should remove the existing installation and upgrade to |
57 |
the latest version: |
58 |
|
59 |
# emerge --sync |
60 |
# emerge --unmerge gnutls |
61 |
# emerge --ask --oneshot --verbose net-libs/gnutls |
62 |
|
63 |
Due to small API changes with the previous version, please do the |
64 |
following to ensure your applications are using the latest GnuTLS that |
65 |
you just emerged. |
66 |
|
67 |
# revdep-rebuild --soname-regexp libgnutls.so.1[0-1] |
68 |
|
69 |
Previously exported RSA keys can be fixed by executing the following |
70 |
command on the key files: |
71 |
|
72 |
# certtool -k infile outfile |
73 |
|
