Name of the Vulnerable Software and Affected Versions libdoc through 2019-01-28

Description The issue arises from a division by zero error in the calcFileBlockOffset function within ole.c. This error occurs due to insufficient input validation, allowing for a potential crash or other unintended behavior when a zero value is used in a calculation.

Recommendations For versions through 2019-01-28, consider adding input validation to prevent division by zero errors in the calcFileBlockOffset function as a temporary workaround until a patch is available.
