Package : ruby2.5 Version : 2.5.5-3+deb10u6 CVE ID : CVE-2021-33621 CVE-2022-28739 Debian Bug : 1009957 1024800 1037178

A couple of security issues were discovered in ruby2.5, the Ruby interpreter, and are as follows -

CVE-2021-33621

Hiroshi Tokumaru discovered that Ruby did not properly handle certain user input for applications the generate HTTP responses using cgi gem. An attacker could possibly use this issue to maliciously modify the response a user would receive from a vulnerable application.

CVE-2022-28739

It was discovered that Ruby incorrectly handled certain inputs.
An attacker could possibly use this issue to expose sensitive information.

For Debian 10 buster, these problems have been fixed, along with the regressions caused by the last Ruby update, in version 2.5.5-3+deb10u6.

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:
