commit 2ce2743ed3ab62ba5328e3da9075a7ce380af264 Author: Sergey Popov <pinkbyte@gentoo.org> Date: Thu Feb 2 17:40:09 2017 +0300 net-misc/quagga: version bump Gentoo-Bug: 607212 Package-Manager: portage-2.3.3 Arches, please test and mark stable =net-misc/quagga-1.1.1 Target keywords: alpha amd64 arm hppa ppc sparc x86 CVE-2017-5495 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2017-5495): 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. amd64 stable x86 stable ppc stable arm stable Stable on alpha. sparc stable. Maintainer(s), please cleanup. Security, please vote. GLSA Vote: No @ Maintainer(s): Please cleanup and drop =net-misc/quagga-1.1.0-r2! Cleanup is done, marking this as FIXED |
