HighMetricsAV:N/AC:L/Au:N/C:N/I:N/A:C
Name of the Vulnerable Software and Affected Versions
Apache POI versions prior to 3.17
Description
The issue is related to Denial of Service Attacks. It involves two main problems:
- Infinite Loops while parsing crafted WMF, EMF, MSG, and macros,
- Out of Memory Exceptions while parsing crafted DOC, PPT, and XLS. This can be exploited by a remote attacker to cause a denial of service.
Recommendations
For versions prior to 3.17, update to release 3.17 or later to resolve the issue.
As a temporary workaround, consider restricting the parsing of crafted files to minimize the risk of exploitation.
Avoid using the vulnerable functions related to parsing WMF, EMF, MSG, macros, DOC, PPT, and XLS until the issue is resolved.
