CVE-2018-19044 (CCN-152793)

Assigned:2018-11-08
Published:2018-11-08
Updated:2019-08-06
Summary: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.
