Quagga bgpd denial of service
| quagga-bgpd-dos (36551) |  Low Risk |
Description:
Quagga is vulnerable to a denial of service, caused by the improper handling of messages and attributes by the bgpd daemon. If the debugging of BGP updates is enabled, a remote authenticated attacker could send a specially-crafted "OPEN" message or "COMMUNITY" attribute, to cause the server to crash.
Platforms Affected:
- Canonical, Ubuntu 6.06 LTS
- Canonical, Ubuntu 6.10
- Canonical, Ubuntu 7.04
- Debian, Debian Linux 3.1
- Debian, Debian Linux 4.0
- MandrakeSoft, Mandrake Linux Corporate Server 4.0 X86_64
- MandrakeSoft, Mandrake Linux Corporate Server 4.0
- Quagga, Quagga prior to 0.99.9
- Sun, Solaris 10 SPARC
- Sun, Solaris 10 x86
Remedy:
Upgrade to the current version of Quagga (unstable release 0.99.9 or later) available from the Quagga Software Routing Suite Web site. See References.
For Ubuntu Linux (quagga):
Refer to USN-512-1 for patch, upgrade, or suggested workaround information. See References.
For Sun Solaris 10 x86 and SPARC:
