DESCRIPTION:
Multiple vulnerabilities have been reported in LibreOffice, which can
be exploited by malicious people to compromise a user's system.

1) An error when handling tag hierarchy within an XML manifest file
can be exploited to cause a heap-based buffer overflow.

2) A boundary error when duplicating certain tags within an XML
manifest file can be exploited to cause a heap-based buffer
overflow.

3) An error within the Base64 decoder implementation when exporting
an XML manifest file can be exploited to cause a heap-based buffer
overflow.

Successful exploitation of the vulnerabilities may allow execution of
arbitrary code, but requires tricking a user into opening a specially
crafted ODF file.

The vulnerabilities are reported in versions prior to 3.5.5 and
3.6.0.

SOLUTION:
Update to version 3.5.5 or 3.6.0.

PROVIDED AND/OR DISCOVERED BY:
The vendor credits Timo Warns, PRE-CERT.
