Re: [libreoffice-users] Attempting to open any Microsoft XML document causes General I/O error after upgrade to 4.1

FWIW:
I do not know the correlation of versions between LO and AOO, but today 
I got the following two security reports from the AOO users forum:

-------------------------------------------------------

CVE-2013-2189
OpenOffice DOC Memory Corruption Vulnerability

Severity: Important
Vendor: The Apache Software Foundation

Versions Affected:
    Apache OpenOffice 3.4.0 to 3.4.1 on all platforms.
    Predecessor versions of OpenOffice.org may be also affected.

Description:

    The vulnerability is caused by operating on invalid PLCF (Plex of
Character Positions in File) data when parsing a malformed DOC document
file. Specially crafted documents can be used for denial-of-service
attacks. Further exploits are possible but have not been verified.

Mitigation:

    Apache OpenOffice 3.4 users are advised to upgrade to Apache
OpenOffice 4.0. Users who are unable to upgrade immediately should be
cautious when opening untrusted documents.

Credits:

    The Apache OpenOffice Security Team credits Jeremy Brown of
Microsoft Vulnerability Research as the discoverer of this flaw.

CVE-2013-4156
OpenOffice DOCM Memory Corruption Vulnerability

Severity: Important

Versions Affected:
    Apache OpenOffice 3.4.0 and 3.4.1, on all platforms.
    Predecessor versions of OpenOffice.org may be also affected.

Description:

    The vulnerability is caused by mishandling of unknown XML elements
when parsing a OOXML document file. Specially crafted documents can be
used for memory-corruption attacks. Further exploits are possible but
have not been verified.

Mitigation

    Apache OpenOffice 3.4.0 and 3.4.1 users are advised to upgrade to
Apache OpenOffice 4.0. Users who are unable to upgrade immediately
should be cautious when opening untrusted documents.

Credits

    The Apache OpenOffice Security Team credits Jeremy Brown of
Microsoft Vulnerability Research as the discoverer of this flaw.

Could this be related, in that now LO 4.1 rejects such files where LO 
4.0 did not?
Just a messenger.
