Debian Security Advisory

DLA-2095-1 storebackup -- LTS security update

Date Reported:

05 Feb 2020

Affected Packages:

storebackup

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 949393.
In Mitre's CVE dictionary: CVE-2020-7040.

More information:

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.
