GSD-2013-6421

Vulnerability from gsd - Updated: 2013-12-02 00:00
Details
sprout Gem for Ruby contains a flaw in the unpack_zip() function in archive_unpacker.rb. The issue is due to the program failing to properly sanitize input passed via the 'zip_file', 'dir', 'zip_name', and 'output' parameters. This may allow a context-dependent attacker to execute arbitrary code.
