Keepalived: Denial of Service

Keepalived: Denial of Service Keepalived uses world-writable PID files, allowing a local attacker to kill arbitrary processes. keepalived 2012-07-09 2012-07-09 371469 local 1.2.2-r3 1.2.2-r3

Keepalived is a strong & robust keepalive facility to the Linux Virtual Server project.

The "pidfile_write()" function in pidfile.c in Keepalived writes PID files with insecure permissions.

A local attacker may be able to cause a Denial of Service of arbitrary processes.

There is no known workaround at this time.

All Keepalived users should upgrade to the latest version:


      # emerge --sync
      # emerge --ask --oneshot --verbose ">=sys-cluster/keepalived-1.2.2-r3"
