Description

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).

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).

For the oldstable distribution (jessie), these problems have been fixed in version 0.99.23.1-1+deb8u5.

For the stable distribution (stretch), these problems have been fixed in version 1.1.1-3+deb9u2.

We recommend that you upgrade your quagga packages.

Thanks for sharing. Debian security updates get automatically pulled in every night diring creation of the rolling release ISO.

c-po, does it mean that the fix will be included in an upcoming 1.1 release and in 1.2.0 when released ?

syncer subscribed.May 3 2018, 11:59 AM

@c-po vyatta-quagga is our package

@syncer my bad ... then we have to integrate the fixes manually or better, identify why we have to use a special version and decide if this is still necessary. A lot of patches from the past have been removed in the latest Kernel update, too which were no longer necessary.

I think we can use Debian jessie package for 1.2.0-rolling. But for 1.1, we have to build special version, because there is no upstream package.

@syncer @higebu Yes, stock quagga is missing many things that ours has. We have no choice other than to integrate the patches by hand.
