Red Hat Security Advisory: php security update

Important

A flaw was found in PHP, specifically within the PHP-FPM status page. Due to improper sanitation of user data, a remote attacker can craft a malicious URL. When a user views the PHP-FPM status page with this crafted URL, it can lead to the execution of arbitrary JavaScript code (Cross-Site Scripting or XSS) on their machine, potentially compromising their browser session or leading to further attacks.

CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

A flaw was found in PHP. Some functions, including `urldecode()`, incorrectly pass signed characters to character type (ctype) functions. On certain systems, this can lead to accessing memory with a negative offset. This vulnerability can be exploited by an attacker to trigger a denial of service (DoS), making the affected PHP application or system unavailable.

CWE-839 - Numeric Range Comparison Without Minimum Check

A flaw was found in PHP. When an attacker input can influence the encoding passed to `mb_regex_encoding()` and the application subsequently uses mbregex search APIs, a NULL pointer dereference can occur due to a mismatch between the Oniguruma and mbfl encoding support. This issue can cause a crash in the PHP process, resulting in a denial of service.

CWE-476 - NULL Pointer Dereference

A flaw was found in PHP. When a PHP SOAP server has a typemap configured, the apache:Map decoding process checks the incorrect variable in case of a missing value element. This incorrect check leads to a NULL pointer dereference and allows a remote unauthenticated attacker to crash the PHP SOAP server process, resulting in a denial of service.
