TITLE:
VeriSign ConfigChk ActiveX Control Buffer Overflow
SECUNIA ADVISORY ID:
SA24249
VERIFY ADVISORY:
http://secunia.com/advisories/24249/
CRITICAL:
Highly critical
IMPACT:
System access
WHERE:
>From remote
SOFTWARE:
VeriSign ConfigChk ActiveX Control 2.x
http://secunia.com/product/13547/
DESCRIPTION:
David D. Rude II has reported a vulnerability in VeriSign's ConfigChk
ActiveX control, which can be exploited by malicious people to
compromise a user's system.
The vulnerability is caused due to a boundary error within the
ConfigChk ActiveX control (VSCnfChk.dll) when processing arguments
passed to the VerCompare() method. This can be exploited to cause a
stack-based based buffer overflow via an overly long (greater than 28
bytes) string passed as argument to the said method.
Successful exploitation allows execution of arbitrary code but
requires that the user is e.g. tricked into visiting a malicious web
site.
The vulnerability is reported in version 2.0.0.2. Other versions may
also be affected.
SOLUTION:
Apply patches.
