GSD-2013-4203
Vulnerability from gsd - Updated: 2013-08-02 00:00Details
rgpg Gem for Ruby contains a flaw in the GpgHelper module
(lib/rgpg/gpg_helper.rb). The issue is due to the program failing to properly
sanitize user-supplied input before being used in the system() function for
execution. This may allow a remote attacker to execute arbitrary commands.
