Two vulnerabilities exist in the Compressed Folders function: 

An unchecked buffer exists in the programs that handles
the decompressing of files from a zipped file. A
security vulnerability results because attempts to open
a file with a specially malformed filename contained in
a zipped file could possibly result in Windows Explorer
failing, or in code of the attacker's choice being run.

The decompression function could place a file in a
directory that was not the same as, or a child of, the
target directory specified by the user as where the
decompressed zip files should be placed. This could
allow an attacker to put a file in a known location on
the users system, such as placing a program in a
startup directory

Impact of vulnerability: Two vulnerabilities, the most serious
of which could run code of attacker's choice

Maximum Severity Rating: Moderate 

Recommendation: Consider applying the patch to affected systems 

Affected Software: 

Microsoft Windows 98 with Plus! Pack 
Microsoft Windows Me 
Microsoft Windows XP
