Advisory Content (Page 1 of 3)[ 1 ] [ 2 ] [ 3 ]

Description:
John Heasman has reported some vulnerabilities in OpenOffice, which can be exploited by malicious people to compromise a user's system.

1) A truncation error within the handling of the META_ESCAPE record can be exploited to cause a heap-based buffer overflow via a specially crafted WMF/EMF file.

2) An integer overflow within the handling of EMR_POLYPOLYGON and EMR_POLYPOLYGON16 records can be exploited to cause a heap-based buffer overflow via a specially crafted WMF/EMF file.

Successful exploitation of the vulnerabilities allows execution of arbitrary code and requires that a user is tricked into opening a specially crafted WMF/EMF file or a specially crafted document.

The vulnerabilities are reported in OpenOffice prior to version 2.1.0. Other versions may also be affected.
