What is CVE-2017-0899?

RubyGems versions prior to 2.6.13 are susceptible to vulnerabilities due to crafted gem specifications that can contain terminal escape characters. When such specifications are processed, they can unintentionally execute terminal escape sequences, potentially allowing attackers to influence the behavior of the system. This risk emphasizes the importance of maintaining up-to-date software to mitigate exploitation possibilities.

Affected Version(s)

RubyGems Versions before 2.6.13
