[原文]bacula 1.36.3 and earlier allows local users to modify or read sensitive files via symlink attacks on (1) the temporary file used by autoconf/randpass when openssl is not available, or (2) the mtx.[PID] temporary file in mtx-changer.in.
Bacula contains a flaw that may allow a malicious local user to create or overwrite arbitrary files on the system. The issue is due to /autoconf/randpass creating temporary files in /tmp insecurely. It is possible for a user to use a symlink style attack to manipulate arbitrary files, resulting in a loss of integrity.
Upgrade to version 1.37.39 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
