Update |
17 |
====== |
18 |
|
19 |
While working on the tcpdump issues solved in the original version of |
20 |
this GLSA, Simon L. Nielsen from FreeBSD Security Team discovered a |
21 |
similar infinite loop DoS vulnerability in the BGP handling code |
22 |
(CAN-2005-1267). New packages have been released to address this new |
23 |
issue. |
24 |
|
25 |
The updated sections appear below. |
26 |
|
27 |
Affected packages |
28 |
================= |

Package / Vulnerable / Unaffected |
32 |
------------------------------------------------------------------- |
33 |
1 net-analyzer/tcpdump < 3.8.3-r3 >= 3.8.3-r3 |
34 |
|
35 |
Description |
36 |
=========== |
37 |
|
38 |
TCPDump improperly handles and decodes ISIS (CAN-2005-1278), BGP |
39 |
(CAN-2005-1267, CAN-2005-1279), LDP (CAN-2005-1279) and RSVP |
40 |
(CAN-2005-1280) packets. TCPDump might loop endlessly after receiving |
41 |
malformed packets. |
42 |
|
43 |
Resolution |
44 |
========== |
45 |
|
46 |
All TCPDump users should upgrade to the latest available version: |
47 |
|
48 |
# emerge --sync |
49 |
# emerge --ask --oneshot --verbose ">=net-analyzer/tcpdump-3.8.3-r3" |
50 |
