Details

It was discovered that Ruby failed to validate specification names. An attacker could possibly use a maliciously crafted gem to potentially overwrite any file on the filesystem. (CVE-2017-0901)

It was discovered that Ruby was vulnerable to a DNS hijacking vulnerability. An attacker could use this to possibly force the RubyGems client to download and install gems from a server that the attacker controls. (CVE-2017-0902)

It was discovered that Ruby incorrectly handled certain YAML files. An attacker could use this to possibly execute arbitrary code. (CVE-2017-0903)
