Open the attachment. Since 24.8, it shows a "The file is corrupt and therefore cannot be opened" warning.

https://gerrit.libreoffice.org/c/core/+/170571/4/package/source/zipapi/ZipFile.cxx#1087 marks it as problematic; related to commit efae4fc42d5fe3c0a69757226f38efc10d101194.
Comment 1 Mike Kaganski 2025-02-07 07:13:59 UTC 
BTW: opening the bugdoc in Word 2016 also shows a warning:

> Word found unreadable content in '...'. Do you want to recover ... ?

Comment 3 Michael Stahl (allotropia) 2025-02-12 15:33:00 UTC 
doesn't load:

info:package:4057404:4057404:package/source/zipapi/ZipFile.cxx:1114: LOC non-0 with data descriptor: "settings.xml"

if we disable this check we get:

info:package.xstor:4058198:4058198:package/source/xstor/xstorage.cxx:3871: Rethrow: com.sun.star.packages.zip.ZipIOException message: "/home/ms/lo/master/package/source/zippackage/ZipPackage.cxx:922: Bad Zip File, ZipException: overlapping entries at /home/ms/lo/master/package/source/zipapi/ZipFile.cxx:1455 

Info-Zip also isn't happy:

> unzip -t English\ Roznama.odt 
Archive:  English Roznama.odt
    testing: mimetype                 OK
    testing: Thumbnails/thumbnail.png   OK
    testing: settings.xml             OK
error: invalid zip file with overlapped components (possible zip bomb)
 To unzip the file anyway, rerun the command with UNZIP_DISABLE_ZIPBOMB_DETECTION=TRUE environmnent variable

... document recovery can load the file... so works as intended...

=> NOTABUG
