Priority: medium
Bug ID: 81284
Assignee: [email protected]
Summary: Opening a zero sized file modifies it on the disk with
garbage
Severity: critical
Classification: Unclassified
OS: Linux (All)
Reporter: [email protected]
Hardware: x86-64 (AMD64)
Status: UNCONFIRMED
Version: 4.2.5.2 release
Component: UI
Product: LibreOffice
To reproduce :
1. Create a zero sized file, as myfile.html or myfile.odt or other.
2. Open it in Libreoffice.
3. The file is displayed with garbage bytes. Without saving it, the file on the
disk is modified !!
4. The Debian file command says after that :
$ file myfile.html
Composite Document File V2 Document, No summary info.
Openoffice 4 has the same bug despite of an alert dialog box with a choice.
This bug should be considered as a security hole because it modifies
unexpectedly a file. This file could have a role in the system as .gksu.lock or
others.
All software must not modified involuntary an user file.
On Debian Wheezy 7.5.
