An update that fixes 5 vulnerabilities is now available.
Description:
This update for quagga fixes the security following issues:
- The Quagga BGP daemon contained a bug in the AS_PATH size calculation
that could have been exploited to facilitate a remote denial-of-service
attack via specially crafted BGP UPDATE messages. [CVE-2017-16227,
bsc#1065641]
- The Quagga BGP daemon did not check whether data sent to peers via
NOTIFY had an invalid attribute length. It was possible to exploit this
issue and cause the bgpd process to leak sensitive information over the
network to a configured peer. [CVE-2018-5378, bsc#1079798]
- The Quagga BGP daemon used to double-free memory when processing certain
forms of UPDATE messages. This issue could be exploited by sending an
optional/transitive UPDATE attribute that all conforming eBGP speakers
should pass along. Consequently, a single UPDATE message could have
affected many bgpd processes across a wide area of a network. Through
this vulnerability, attackers could potentially have taken over control
of affected bgpd processes remotely. [CVE-2018-5379, bsc#1079799]
- It was possible to overrun internal BGP code-to-string conversion tables
in the Quagga BGP daemon. Configured peers could have exploited this
issue and cause bgpd to emit debug and warning messages into the logs
that would contained arbitrary bytes. [CVE-2018-5380, bsc#1079800]
- The Quagga BGP daemon could have entered an infinite loop if sent an
invalid OPEN message by a configured peer. If this issue was exploited,
then bgpd would cease to respond to any other events. BGP sessions would
have been dropped and not be reestablished. The CLI interface would have
been unresponsive. The bgpd daemon would have stayed in this state until
restarted. [CVE-2018-5381, bsc#1079801]
