I received by email a zipped xls file. When I tried to unzip this file, I got a
crc error on zip file, but xls file was generated (malformed)
When I tried to open this file, my OO calc use a lot of resource of my computer
and hang up and let my computer to slow. I need to kill calc process to continue

Hi Brian,

This is the problem.
When you tried to unzip the file you got a CRC error, but a XML file was generated.
Try to open it, and you will see the problem.

The usages of hardware resources will be increase a lot.

@fred: i can confirm the hang with m233.

Loading a corrupted file into SO results in hang. Is there a chance for improved
sanity checking?
User email-received a corrupted zip containing a xls. As the zip is still
inflatable the problem arises.

this is not a defect of Calc but an enhancement request. Opening of corrupted
files should not loop the Office but trying to open a file which is known as
corrupt isn't a good idea too.

Tried to open the ZIP with WinZip and can't. So this archive is entirely broken
and you can't expect to get a valid file from it.

BTW the contained file isn't a XLS but a HTML file saved by Excel which isn't
the same.


As discussed for improving the filters this one is yours.
