TITLE:
Baofeng Storm Multiple Buffer Overflow Vulnerabilities

SECUNIA ADVISORY ID:
SA26749

VERIFY ADVISORY:
http://secunia.com/advisories/26749/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
Baofeng Storm 2.x
http://secunia.com/product/15666/

DESCRIPTION:
ZhenHan.Liu has discovered some vulnerabilities in Baofeng Storm,
which can be exploited by malicious people to compromise a user's
system.

1) A boundary error in sparser.dll can be exploited to cause a
stack-based buffer overflow via e.g. an overly long (greater than 260
bytes) string passed as argument to the "rawParse()" and
"advancedOpen()" methods and "URL" property within the
MPS.StormPlayer.1 ActiveX control (mps.dll), or via a specially
crafted .SMPL file containing an overly long (greater than 260 bytes)
"path" string.

2) A boundary error within the MPS.StormPlayer.1 ActiveX control
(mps.dll) when handling the "isDVDPath()" method can be exploited to
cause a stack-based buffer overflow via an overly long (greater than
260 bytes) string passed as argument to the affected method.

3) Boundary errors within the MPS.StormPlayer.1 ActiveX control
(mps.dll) when handling the "backImage()" and "titleImage()"
properties can be exploited to cause heap-based buffer overflows by
assigning an overly long (greater than 260 bytes) string to the
affected properties.

Successful exploitation of the vulnerabilities allow execution of
arbitrary code.

The vulnerabilities are confirmed in version 2.8. Other versions may
also be affected.

SOLUTION:
Set the kill-bit for the affected ActiveX control and do not open
untrusted .SMPL files.
