Amazon Linux 2023 : perl, perl-Attribute-Handlers, perl-AutoLoader (ALAS2023-2023-448)

critical Nessus Plugin ID 186976

Language:

Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-448 advisory.

- A vulnerability was found in perl. This issue occurs when a crafted regular expression is compiled by perl, which can allow an attacker controlled byte buffer overflow in a heap allocated buffer.
(CVE-2023-47038)

- In Perl before 5.38.2, S_parse_uniprop_string in regcomp.c can write to unallocated space because a property name associated with a \p{...} regular expression construct is mishandled. The earliest affected version is 5.30.0. (CVE-2023-47100)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Run 'dnf update perl --releasever 2023.3.20231211' to update your system.
