Two important ReDoS issues have been found in the Ruby programming language; one in the URI component (CVE-2023-28755) and one in the Time component (CVE-2023-28756). It was discovered that the URI parser and the Time parser mishandle invalid URLs that have specific characters, causing an increase in execution time for parsing strings to URI and Time objects.

An attacker could easily exploit these vulnerabilities to cause a denial of service (DoS) with no user interaction required.

With a high availability impact, it is critical that all impacted users apply the Ruby updates issued but their distro(s) as soon as possible to protect against attacks leading to loss of access and potential compromise.
