CVE-2010-1117

Status: ModifiedHigh (7.6)—

Heap-based buffer overflow in Internet Explorer 8 on Microsoft Windows 7 allows remote attackers to discover the base address of a Windows .dll file, and possibly have unspecified other impact, via unknown vectors, as demonstrated by Peter Vreugdenhil during a Pwn2Own competition at CanSecWest 2010.

CVSS
