CVE-2022-26336: poi-scratchpad: A carefully crafted TNEF file can cause an out of memory exception

[PJ Fanning <fanningpj () apache org>]

Severity: moderate

Description:

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.

This issue is being tracked as https://bz.apache.org/bugzilla/show_bug.cgi?id=65899
