DESCRIPTION: Two vulnerabilities have been reported in Microsoft XML Core Services, which can be exploited by malicious people to disclose certain information and compromise a vulnerable system.

1) An unspecified error exists in the XMLHTTP ActiveX control when interpreting a HTTP server-side redirect. This can be exploited to disclose certain information e.g. via a specially crafted web page.

2) A boundary error exists in the XSLT processing in MSXML. This can be exploited to cause a buffer overflow via a specially crafted web page and allows execution of arbitrary code.


SOLUTION: Apply patches.
