MS10-001: Font file decompression vulnerability
MS10-001 addresses a vulnerability (CVE-2010-0018 ) in the LZCOMP de-compressor for Microtype Express Fonts. This blog aims to answer some questions regarding the updates we’ve made in this area. What is the issue? t2embed.dll improperly performs bounds-checking on lengths which are decoded from the LZCOMP bit-stream. This made it possible for a copy loop to violate the intended working buffer.
