Description
storeBackup.pl in storeBackup through 3.5 relies on the /tmp/storeBackup.lock pathname, which allows symlink attacks that possibly lead to privilege escalation. (Local users can also create a plain file named /tmp/storeBackup.lock to block use of storeBackup until an admin manually deletes that file.)
Affected configurations
• storebackup storebackup (<= 3.5)
• debian debian linux 8.0
• opensuse backports sle 15.0
• opensuse leap 15.1
• canonical ubuntu linux 16.04
• canonical ubuntu linux 18.04
• canonical ubuntu linux 20.04
