TITLE:
Yahoo! Widgets YDP ActiveX Control Buffer Overflow Vulnerability

SECUNIA ADVISORY ID:
SA26011

VERIFY ADVISORY:
http://secunia.com/advisories/26011/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
Yahoo! Widgets 4.x
http://secunia.com/product/14324/

DESCRIPTION:
Parvez Anwar has discovered a vulnerability in Yahoo! Widgets, which
can be exploited by malicious people to compromise a vulnerable
system.

The vulnerability is caused due to a boundary error within the
YDPCTL.YDPControl.1 (YDPCTL.dll) ActiveX control when handling the
"GetComponentVersion()" method. This can be exploited to cause a
stack-based buffer overflow by passing an overly long string (greater
than 512 bytes) to the affected method.

Successful exploitation allows execution of arbitrary code.

The vulnerability is confirmed in YDPCTL.dll version 2007.4.13.1
included in Yahoo! Widgets version 4.0.3 (build 178). Other versions
may also be affected.

SOLUTION:
Update to version 4.0.5.
