TITLE:
Microsoft Windows Wordpad Word 97 Converter Vulnerabilities
Criticality level: Highly critical
Impact: System access
Where: From remote
SECUNIA ADVISORY ID:
http://secunia.com/advisories/41387/
DESCRIPTION:
Secunia Research has discovered two vulnerabilities in
Microsoft
Windows, which can be exploited by malicious people to
compromise a
user's system.
The vulnerabilities are caused due to array-indexing errors in
the
Word 97 converter (mswrd8.wpc / mswrd864.wpc) when parsing cell
ranges supplied in sprmTTextFlow and sprmTSplit PRLs. This can
be
exploited to corrupt memory outside the bounds of an allocated
array
by tricking a user into opening a specially crafted Word 97
document
using WordPad.
Successful exploitation may allow execution of arbitrary code.
SOLUTION:
Apply patches.
