Details

It was discovered that Quagga incorrectly handled certain Outbound Route
Filtering (ORF) records. A remote authenticated attacker could use this
flaw to cause a denial of service or potentially execute arbitrary code.
The default compiler options for Ubuntu 8.04 LTS and later should reduce
the vulnerability to a denial of service. (CVE-2010-2948)

It was discovered that Quagga incorrectly parsed certain AS paths. A remote
attacker could use this flaw to cause Quagga to crash, resulting in a
denial of service. (CVE-2010-2949)
