An argument injection vulnerability in Dragonfly Ruby Gem v1.3.0 allows attackers to read and write arbitrary files when the verify_url option is disabled. This vulnerability is exploited via a crafted URL.

An argument injection vulnerability in the Dragonfly gem for Ruby allows remote attackers to read and write to arbitrary files via a crafted URL when the verify_url option is disabled. This may lead to code execution. The problem occurs because the generate and process features mishandle use of the ImageMagick convert utility.

The Dragonfly gem 0.7 before 0.8.6 and 0.9.x before 0.9.13 for Ruby, when used with Ruby on Rails, allows remote attackers to execute arbitrary code via a crafted request.

The gem contains a flaw in Uploading & Processing that is due to the gem failing to restrict arbitrary commands to imagemagicks convert. This may allow a remote attacker to gain read/write access to the filesystem and execute arbitrary commands.

lib/dragonfly/imagemagickutils.rb in the fog-dragonfly gem for Ruby allows remote attackers to execute arbitrary commands via unspecified vectors.

The gem contains a flaw that is due to the program failing to properly escape a shell that contains injected characters. This may allow a context-dependent attacker to potentially execute arbitrary commands.
