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.
