Synopsis |
16 |
======== |
17 |
|
18 |
Multiple vulnerabilities were found in Quagga, the worst of which |
19 |
leading to remote execution of arbitrary code. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
Quagga is a free routing daemon replacing Zebra supporting RIP, OSPF |
25 |
and BGP. |

Description |
36 |
=========== |
37 |
|
38 |
Multiple vulnerabilities have been discovered in Quagga. Please review |
39 |
the CVE identifiers referenced below for details. |
40 |
|
41 |
Impact |
42 |
====== |
43 |
|
44 |
A BGP peer could send a Route-Refresh message with specially-crafted |
45 |
ORF record, which can cause Quagga's bgpd to crash or possibly execute |
46 |
arbitrary code with the privileges of the user running Quagga's bgpd; a |
47 |
BGP update AS path request with unknown AS type, or malformed |
48 |
AS-Pathlimit or Extended-Community attributes could lead to Denial of |
49 |
Service (daemon crash), an error in bgpd when handling AS_PATH |
50 |
attributes within UPDATE messages can |
51 |
be exploited to cause a heap-based buffer overflow resulting in a crash |
52 |
of the |
53 |
daemon and disruption of IPv4 routing, two errors in ospf6d and ospfd |
54 |
can each be exploited to crash the daemon and disrupt IP routing. |
55 |
|
56 |
Workaround |
57 |
========== |
58 |
|
59 |
There is no known workaround at this time. |
60 |
|
61 |
Resolution |
62 |
========== |
63 |
|
64 |
All Quagga users should upgrade to the latest version: |
65 |
|
66 |
# emerge --sync |
67 |
# emerge --ask --oneshot --verbose ">=net-misc/quagga-0.99.20 " |
