Detail
| A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 17.10 - Ubuntu 16.04 LTS Summary: Several security issues were fixed in Ruby. Software Description: - ruby2.3: Interpreter of object-oriented scripting language Ruby 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.ﾃつ (CVE-2017-0903) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 17.10: ﾃつ libruby2.3ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ 2.3.3-1ubuntu1.3 ﾃつ ruby2.3ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ 2.3.3-1ubuntu1.3 Ubuntu 16.04 LTS: ﾃつ libruby2.3ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ 2.3.1-2~16.04.6 ﾃつ ruby2.3ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ 2.3.1-2~16.04.6 In general, a standard system update will make all the necessary changes.
