Synopsis
The remote Amazon Linux 2 host is missing a security update.Description
The version of ruby installed on the remote host is prior to 3.0.6-156. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2RUBY3.0-2023-001 advisory.- A ReDoS issue was discovered in the URI component through 0.12.0 in Ruby through 3.2.1. The URI parser mishandles invalid URLs that have specific characters. It causes an increase in execution time for parsing strings to URI objects. The fixed versions are 0.12.1, 0.11.1, 0.10.2 and 0.10.0.1. (CVE-2023-28755)
- A ReDoS issue was discovered in the Time component through 0.2.1 in Ruby through 3.2.1. The Time parser mishandles invalid URLs that have specific characters. It causes an increase in execution time for parsing strings to Time objects. The fixed versions are 0.1.1 and 0.2.2. (CVE-2023-28756)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
