==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 22.04 LTS

Summary:

PCRE could be made to expose sensitive information.

Software Description:
- pcre2: Perl 5 Compatible Regular Expression Library

Details:

It was discovered that PCRE incorrectly handled memory when
handling certain regular expressions. An attacker could possibly
use this issue to cause applications using PCRE to expose
sensitive information.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 22.04 LTS:
   libpcre2-16-0                   10.39-3ubuntu0.1
