    CVE-2022-26336

    Published: 4 Mar 2022Last Modified: 24 Oct 2026

    Summary: A carefully crafted TNEF file can cause an out of memory exception

    Details: A shortcoming in the HMEF package of poi-scratchpad (Apache POI) allows an attacker to cause an Out of Memory exception. This package is used to read TNEF files (Microsoft Outlook and Microsoft Exchange Server). If an application uses poi-scratchpad to parse TNEF files and the application allows untrusted users to supply them, then a carefully crafted file can cause an Out of Memory exception. This issue affects poi-scratchpad version 5.2.0 and prior versions. Users are recommended to upgrade to poi-scratchpad 5.2.1.
