Red Hat Security Advisory: Red Hat Hardened Images RPMs bug fix and enhancement update
Severity
Important
Notes
Topic: An update for Red Hat Hardened Images RPMs is now available.
Details: This update includes the following RPMs:
composer:
* composer-2.9.7-1.hum1 (noarch)
* composer-2.9.7-1.hum1.src (src)

A flaw was found in Composer, a dependency manager for PHP. A remote attacker could exploit this by injecting ANSI control characters into the terminal output of various Composer commands when Composer downloads from attacker-controlled remote sources. This can lead to mangled output, causing confusion or a Denial of Service (DoS) of the terminal application.
CWE-74 - Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')
