Description

The remote Ubuntu 20.04 LTS / 22.04 LTS / 23.10 host has packages installed that are affected by a vulnerability as referenced in the USN-6853-1 advisory.

 It was discovered that Ruby incorrectly handled the ungetbyte and ungetc methods. A remote attacker could use this issue to cause Ruby to crash, resulting in a denial of service, or possibly obtain sensitive information.
