Package : storebackup Version : 3.2.1-1+deb8u1 CVE ID : CVE-2020-7040 Debian Bug : 949393
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.
For Debian 8 "Jessie", this problem has been fixed in version 3.2.1-1+deb8u1.
We recommend that you upgrade your storebackup packages.
