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

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

- Ubuntu 23.10
- Ubuntu 23.04
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS

Summary:

Several security issues were fixed in Perl.

Software Description:
- perl: Practical Extraction and Report Language

Details:

It was discovered that Perl incorrectly handled printing certain warning
messages. An attacker could possibly use this issue to cause Perl to
consume resources, leading to a denial of service. This issue only affected
Ubuntu 22.04 LTS. (CVE-2022-48522)

Nathan Mills discovered that Perl incorrectly handled certain regular
expressions. An attacker could use this issue to cause Perl to crash,
resulting in a denial of service, or possibly execute arbitrary code.
(CVE-2023-47038)

Update instructions:

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

Ubuntu 23.10:
   perl                            5.36.0-9ubuntu1.1

Ubuntu 23.04:
   perl                            5.36.0-7ubuntu0.23.04.2

Ubuntu 22.04 LTS:
   perl                            5.34.0-3ubuntu1.3

Ubuntu 20.04 LTS:
   perl                            5.30.0-9ubuntu0.5

In general, a standard system update will make all the necessary changes.
