Mandriva Linux Security Advisory : keepalived (MDVSA-2013:096)

This script is Copyright (C) 2013-2016 Tenable Network Security, Inc.


Synopsis :

The remote Mandriva Linux host is missing a security update.

Description :

Updated keepalived package fixes security vulnerability :

The pidfile_write function in core/pidfile.c in keepalived 1.2.2 and
earlier uses 0666 permissions for the (1) keepalived.pid, (2)
checkers.pid, and (3) vrrp.pid files in /var/run/, which allows local
users to kill arbitrary processes by writing a PID to one of these
files (CVE-2011-1784).

A security issue due to syslog being used inside of sighandlers has
also been fixed.

Finally, keepalived was failing to load the ip_vs kernel module
because of an incorrect modprobe option. This has also been corrected.

Solution :

Update the affected keepalived package.

Risk factor :

Low / CVSS Base Score : 3.6
(CVSS2#AV:L/AC:L/Au:N/C:N/I:P/A:P)
CVSS Temporal Score : 3.1
(CVSS2#E:ND/RL:OF/RC:C)
Public Exploit Available : true
