Clamscan Crashes on AIX When Scanning ZIP Files Containing MS-EXE/DLL Files

[caiusionduca]

Hello,

I am encountering an issue with ClamAV on AIX 7.2. Specifically, Clamscan crashes when scanning certain ZIP or JAR files that contain MS-EXE/DLL files inside. For example:

/var/ibm/InstallationManager/bundles/plugins/com.ibm.ws.check.os.v80_8.0.5024.20230413_1800.jar
/opt/freeware/lib/python3.7/ensurepip/_bundled/pip-22.0.4-py3-none-any.whl
This issue seems to occur only with files containing Windows executables or libraries (MS-EXE/DLL). Other ZIP or JAR files without these contents scan successfully.

I am using ClamAV version 1:1.0.7-2.ppc. The crashes do not produce meaningful error messages, making it difficult to identify the root cause.

Has anyone else experienced this issue on AIX or other platforms? Are there known workarounds or fixes for handling such files without causing Clamscan to crash?

I would greatly appreciate any guidance or suggestions from the community.

Thank you in advance for your help!
