Package : ruby2.5 Version : 2.5.5-3+deb10u5 CVE IDs : CVE-2023-28755 CVE-2023-28756

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.

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.

For the detailed security status of ruby2.5 please refer to its security tracker page at:
