All versions of Quagga, 0.93 through 1.1.0, are vulnerable to an unbounded
memory allocation in the telnet 'vty' CLI, leading to a Denial-of-Service of
Quagga daemons, or even the entire host. When Quagga daemons are configured
with their telnet CLI enabled, anyone who can connect to the TCP ports can
trigger this vulnerability, prior to authentication. Most distributions
restrict the Quagga telnet interface to local access only by default. The
Quagga telnet interface 'vty' input buffer grows automatically, without
bound, so long as a newline is not entered. This allows an attacker to cause
the Quagga daemon to allocate unbounded memory by sending very long strings
without a newline. Eventually the daemon is terminated by the system, or the
system itself runs out of memory. This is fixed in Quagga 1.1.1 and Free
Range Routing (FRR) Protocol Suite 2017-01-10.
Stable for HPPA.
Stable on alpha.
