Heap-based buffer overflow in the substringData method in Microsoft Internet Explorer 6 and 7 allows remote attackers to execute arbitrary code, related to an unspecified manipulation of a DOM object before a call to this method, aka the “HTML Objects Memory Corruption Vulnerability.”

Microsoft Windows XP SP2 and SP3, Server 2003 SP1 and SP2, Vista Gold and SP1, and Server 2008 allows remote attackers to cause a denial of service (system hang) via a series of Pragmatic General Multicast (PGM) packets with invalid fragment options, aka the “PGM Malformed Fragment Vulnerability.”

Microsoft Windows XP SP2 and SP3, and Server 2003 SP1 and SP2, does not properly validate the option length field in Pragmatic General Multicast (PGM) packets, which allows remote attackers to cause a denial of service (infinite loop and system hang) via a crafted PGM packet, aka the “PGM Invalid Length Vulnerability.”

Unspecified vulnerability in Microsoft Malware Protection Engine (mpengine.dll) 1.1.3520.0 and 0.1.13.192, as used in multiple Microsoft products, allows context-dependent attackers to cause a denial of service (disk space exhaustion) via a file with “crafted data structures” that trigger the creation of large temporary files, a different vulnerability than CVE-2008-1437.
