CVE-2025-40907

FastCGI Perl bingdings.

Security Fix(es):

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)

The perl-FCGI package provides a Perl module for writing FastCGI applications. FastCGI is a more efficient alternative to traditional CGI, as it keeps application processes persistent across multiple requests. This module allows Perl web applications to handle requests faster and with lower resource overhead, making it suitable for high-traffic environments.
