Version 0.2.0 of the octopoller gem was published containing world-writeable files. Specifically, the gem was packed with files having their permissions set to
-rw-rw-rw- (i.e. 0666) instead of
rw-r--r-- (i.e. 0644).
This means everyone who is not the owner (Group and Public) with access to the instance where this release had been installed could modify the world-writable files from this gem.
Malicious code already present and running on your machine, separate from this package, could modify the gem’s files and change its behavior during runtime.
Users can use the previous version of the gem v0.1.0. Alternatively, users can modify the file permissions manually until they are able to upgrade to the latest version.
