Microsoft issued two new patches and re-issued one other patch on their monthly patch Tuesday. MS05-054 is “Cumulative Security Update for Internet Explorer,” yes, IE, that exploit delivery engine that also displays web pages. Get it patched, and use it only when absolutely necessary! MS05-055 is a very specific patch for Windows 2000 SP4 that patches an exploit which would allow an elevation of privileges. MS05-050, “Vulnerability in DirectShow Could Allow Remote Code Execution” was re-released to for a “revised version” of the security update for users of Windows 2000 SP4, Windows XP SP1 and Windows 2003 – sounds like a patch to the patch.
