Summary
The remote host is missing an update for the 'storebackup' package(s) announced via the DLA-2095-1 advisory.
Insight
Insight
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 Software
Affected Software
'storebackup' package(s) on Debian Linux.
Detection Method
Detection Method
Checks if a vulnerable package version is present on the target host.
Solution
Solution
