Amazon Linux 2 : perl-FCGI (ALAS-2025-2880)

medium Nessus Plugin ID 238354

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of perl-FCGI installed on the remote host is prior to 0.74-8. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2025-2880 advisory.

FCGI versions 0.44 through 0.82, for Perl, include a vulnerable version of the FastCGI fcgi2 (aka fcgi) library.

The included FastCGI library is affected by CVE-2025-23016, causing an integer overflow (and resultant heap-based buffer overflow) via crafted nameLen or valueLen values in data to the IPC socket. This occurs in ReadParams in fcgiapp.c. (CVE-2025-40907)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

Solution

Run 'yum update perl-FCGI' to update your system.
