ALSA-2022:1930
Vulnerability from osv_almalinux – Published: 2022-05-10 06:39 – Updated: 2022-05-10 08:08 – Source websiteThe keepalived utility provides simple and robust facilities for load balancing and high availability. The load balancing framework relies on the well-known and widely used IP Virtual Server (IPVS) kernel module providing layer-4 (transport layer) load balancing. Keepalived implements a set of checkers to dynamically and adaptively maintain and manage a load balanced server pool according to the health of the servers. Keepalived also implements the Virtual Router Redundancy Protocol (VRRPv2) to achieve high availability with director failover.
Security Fix(es):
- keepalived: dbus access control bypass (CVE-2021-44225)
