TITLE:
Microsoft Visual Studio Active Template Library Three Vulnerabilities
SECUNIA ADVISORY ID:
SA35967
VERIFY ADVISORY:
http://secunia.com/advisories/35967/
DESCRIPTION:
Some vulnerabilities have been reported in Microsoft Visual Studio,
which can be exploited by malicious people to potentially bypass
security features, gain knowledge of sensitive information, or
compromise applications built using ATL (Active Template Library).
1) An error in the ATL headers when handling persisted streams can be
exploited to cause VariantClear() to be called on a VARIANT that has
not been correctly initialised. This can e.g. be exploited to corrupt
memory via a web page passing a specially crafted stream to a
vulnerable control.
Successful exploitation may allow execution of arbitrary code.
2) An error in the ATL headers when handling object instantiation
from data streams may allow bypassing of security policies such as
kill-bits in Internet Explorer if a control or component uses
OleLoadFromStream() in an unsafe manner.
3) An error in ATL may result in a string being read without
terminating NULL bytes, which can be exploited to disclose memory
contents beyond the end of the string.
SOLUTION:
Apply patches.
