RHEL 6 : quagga (Unpatched Vulnerability)

critical Nessus Plugin ID 199343

Synopsis

The remote Red Hat 6 host is affected by multiple vulnerabilities that will not be patched.

Description

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

- quagga: Double free vulnerability in bgpd when processing certain forms of UPDATE message allowing to crash or potentially execute arbitrary code (CVE-2018-5379)

- quagga (ospf6d) 0.99.21 has a DoS flaw in the way the ospf6d daemon performs routes removal (CVE-2012-5521)

- The aspath_put function in bgpd/bgp_aspath.c in Quagga before 1.2.2 allows remote attackers to cause a denial of service (session drop) via BGP UPDATE messages, because AS_PATH size calculation for long paths counts certain bytes twice and consequently constructs an invalid message. (CVE-2017-16227)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

Solution

The vendor has acknowledged the vulnerabilities but no solution has been provided. Refer to the vendor for remediation guidance.
