\n Bulletin Summary for April 2006.<\/p>\n
\n in Microsoft Windows and Internet Explorer. Exploitation of these
\n vulnerabilities could allow a remote, unauthenticated attacker to
\n execute arbitrary code or cause a denial of service on a vulnerable
\n system.<\/p>\n
\n vulnerabilities in Microsoft Windows and Internet Explorer. Further
\n information is available in the following US-CERT Vulnerability Notes:<\/p>\n
\n vulnerability<\/p>\n
\n createTextRange() DHTML method, possibly allowing a remote,
\n unauthenticated attacker to execute arbitrary code.
\n (CVE-2006-1359)<\/p>\n
\n processing script action handlers<\/p>\n
\n allow a remote attacker to crash the browser or possibly execute
\n arbitrary code on a vulnerable system.
\n (CVE-2006-1245)<\/p>\n
\n files<\/p>\n
\n vulnerability may allow a remote attacker to execute arbitrary code.
\n (CVE-2006-1388)<\/p>\n
\n crafted, malformed HTML<\/p>\n
\n This vulnerability may allow a remote attacker to execute arbitrary
\n code on a vulnerable system.
\n (CVE-2006-1185)<\/p>\n
\n Internet Explorer<\/p>\n
\n designed for use in the browser, which may allow a remote attacker to
\n execute arbitrary code or crash IE.
\n (CVE-2006-1186)<\/p>\n
\n elements with a specially crafted tag<\/p>\n
\n tags, which may allow a remote, unauthenticated attacker to execute
\n arbitrary code.
\n (CVE-2006-1188)<\/p>\n
\n double-byte characters in specially crafted URLs<\/p>\n
\n characters in URLs, which may allow a remote, unauthenticated attacker
\n to execute arbitrary code.
\n (CVE-2006-1189)<\/p>\n
\n RDS.Dataspace ActiveX control in MDAC<\/p>\n
\n control possibly allowing a remote attacker to execute arbitrary code.
\n (CVE-2006-0003)<\/p>\n
\n objects<\/p>\n
\n vulnerability may allow a remote unauthenticated attacker to execute
\n arbitrary code on a vulnerable system.
\n (CVE-2006-0012)<\/p>\n
\n the privileges of the user. If the user is logged on with
\n administrative privileges, the attacker could take complete control of
\n an affected system. An attacker may also be able to cause a denial of
\n service.<\/p>\n
