Alpine: multiple quagga packages: security update to 1.1.0-r0 (deprecated)

high Tenable Cloud Security Plugin ID 400941

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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. (CVE-2017-5495)
