[3.7] libreoffice: Remote arbitrary file disclosure vulnerability via WEBSERVICE formula (CVE-2018-6871)
LibreOffice Calc supports a WEBSERVICE function to obtain data by URL.
Vulnerable versions of LibreOffice allow
WEBSERVICE to take a local file URL (e.g file://) which can be used to
inject local files into the spreadsheet without
warning the user. Subsequent formulas can operate on that inserted data
and construct a remote URL whose
path leaks the local data to a remote attacker.
In later versions of LibreOffice without this flaw, WEBSERVICE has now
been limited to accessing http and https URLs
along with bringing WEBSERVICE URLs under LibreOffice Calc’s link
management infrastructure.
Fixed in:
LibreOffice 5.4.5/6.0.1
