CVE-2018-19046

CWE-200
 

 
keepalived 2.0.8 didn't check for existing plain files when writing data to a temporary file upon a call to PrintData or PrintStats. If a local attacker had previously created a file with the expected name (e.g., /tmp/keepalived.data or /tmp/keepalived.stats), with read access for the attacker and write access for the keepalived process, then this potentially leaked sensitive information.

 
 
CVE-2018-19045

CWE-200
 

 
keepalived 2.0.8 used mode 0666 when creating new temporary files upon a call to PrintData or PrintStats, potentially leaking sensitive information.

 
 
CVE-2018-19044

CWE-59
 

 
keepalived 2.0.8 didn't check for pathnames with symlinks when writing data to a temporary file upon a call to PrintData or PrintStats. This allowed local users to overwrite arbitrary files if fs.protected_symlinks is set to 0, as demonstrated by a symlink from /tmp/keepalived.data or /tmp/keepalived.stats to /etc/passwd.

CVE-2011-1784

CWE-264
 

 
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.
