TeraCopy 2.3 (default.mo) Language File Integer Overflow Vulnerability
[#!J:\Perl\bin\perl.exe
#
#
# TeraCopy 2.3 (default.mo) Language File Integer Overflow Vulnerability
#
#
# Vendor: Code Sector
# Product web page: http://www.codesector.com
# Affected version: 2.27 and 2.3 beta 2
#
# Summary: TeraCopy is designed to copy and move files at the maximum
# possible speed. It skips bad files during the copying process, and
# then displays them at the end of the transfer so that you can see
# which ones need attention. TeraCopy can automatically check the copied
# files for errors by calculating their CRC checksum values. It also
# provides a lot more information about the files being copied than its
# Windows counterpart. TeraCopy integrates with Windows Explorer's
# right-click menu and can be set as the default copy handler.
#
# Desc: TeraCopy is prone to an integer overflow vulnerability because
# it fails to perform adequate boundary checks when reading language files.
# Successfully exploiting this issue may allow local attackers to execute
# arbitrary code in the context of the application. Failed exploit attempts
# will cause denial-of-service conditions.
#
# Tested on: Microsoft Windows Server 2008 R2 EN (64-bit)
# Microsoft Windows 7 Ultimate SP1 EN (32-bit)
#
#
# Vulnerability discovered by Gjoko 'LiquidWorm' Krstic
