Description Vincent Danen 2013-01-07 21:48:35 UTC
Michael Scherer discovered that the ruby_parser ruby gem did not create temporary files in a safe manner.  In /usr/share/gems/gems/ruby_parser-2.0.4/lib/gauntlet_rubyparser.rb's diff_pp function it creates files as /tmp/a.[pid] and /tmp/b.[pid] which can be predicted and used for either a denial of service (file cannot be overwritten), or to change the contents of a files that are writable.

The initial report is in bug #892221.

Upstream had been notified as per comment #1 but apparently there was no response.  Upstream version 3.1.1 is still vulnerable (verified via download and on github).
