More information:

Two regular expression Denial of Service (ReDoS) issues were discovered in Ruby: the first in the URI component, and the second in the Time module. Each of these issues could have resulted in a dramatic increase in execution time given malicious input.

• CVE-2023-28755

  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-2023-28756

  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.

For Debian 10 Buster, these problems have been fixed in version 2.5.5-3+deb10u5.

We recommend that you upgrade your ruby2.5 packages.
