3) Description of Vulnerability
Secunia Research has discovered four vulnerabilities in NTR ActiveX
control, which can be exploited by malicious people to compromise a
user's system.
1) A boundary error in the handling of the "StartModule()" method can
be exploited to cause a stack-based buffer overflow via an overly long
"bstrUrl" parameter.
2) A boundary error when constructing an url can be exploited to cause
a stack-based buffer overflow via e.g. an overly long, specially
crafted "bstrParams" parameter passed to the "Check()" method.
3) A boundary error when constructing the path to a .ntr file can be
exploited to cause a limited stack-based buffer overflow via an overly
long, specially crafted "bstrUrl" parameter passed to the "Download()"
or "DownloadModule()" methods.
4) A boundary error when constructing an url can be exploited to cause
a stack-based buffer overflow via an overly long, specially crafted
"bstrUrl" parameter passed to the "Download()" or "DownloadModule()"
methods.
Successful exploitation of the vulnerabilities allows execution of
arbitrary code.
The Common Vulnerabilities and Exposures (CVE) project has assigned
CVE-2012-0266 for the vulnerabilities.
