Package : quagga
Version : 0.99.22.4-1+wheezy3+deb7u3
CVE ID : CVE-2018-5379 CVE-2018-5380 CVE-2018-5381
Several vulnerabilities have been discovered in Quagga, a routing
daemon. The Common Vulnerabilities and Exposures project identifies the
following issues:
CVE-2018-5378
It was discovered that the Quagga BGP daemon, bgpd, does not
properly bounds check data sent with a NOTIFY to a peer, if an
attribute length is invalid. A configured BGP peer can take
advantage of this bug to read memory from the bgpd process or cause
a denial of service (daemon crash).
https://www.quagga.net/security/Quagga-2018-0543.txt
CVE-2018-5379
It was discovered that the Quagga BGP daemon, bgpd, can double-free
memory when processing certain forms of UPDATE message, containing
cluster-list and/or unknown attributes, resulting in a denial of
service (bgpd daemon crash).
https://www.quagga.net/security/Quagga-2018-1114.txt
CVE-2018-5380
It was discovered that the Quagga BGP daemon, bgpd, does not
properly handle internal BGP code-to-string conversion tables.
https://www.quagga.net/security/Quagga-2018-1550.txt
CVE-2018-5381
It was discovered that the Quagga BGP daemon, bgpd, can enter an
infinite loop if sent an invalid OPEN message by a configured peer.
A configured peer can take advantage of this flaw to cause a denial
of service (bgpd daemon not responding to any other events; BGP
sessions will drop and not be reestablished; unresponsive CLI
interface).
https://www.quagga.net/security/Quagga-2018-1975.txt
For Debian 7 "Wheezy", these problems have been fixed in version
0.99.22.4-1+wheezy3+deb7u3.
We recommend that you upgrade your quagga packages.
