RLSA-2026:49914 (CVE-2026-14355)

Vulnerability from osv_rocky – Published: 2026-08-14 00:06 – Updated: 2026-08-28 00:11 – Source website

Summary

Low: php8.4 security, bug fix, and enhancement update

Details

PHP is an HTML-embedded scripting language. PHP attempts to make it easy for developers to write dynamically generated web pages. PHP also offers built-in database integration for several commercial and non-commercial database management systems, so writing a database-enabled webpage with PHP is fairly simple. The most common use of PHP coding is probably as a replacement for CGI scripts.

Security Fix(es):

php: PHP OpenSSL extension: Denial of Service due to buffer allocation flaw in AES-WRAP-PAD (CVE-2026-14355)

Bug Fix(es) and Enhancement(s):

Rebase PHP to 8.4.23 for CVE-2026-14355 in 10.2.z (JIRA:Rocky Linux-192616)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

CVE-2026-14355 (GCVE-0-2026-14355)

Vulnerability from cvelistv5 – Published: 2026-07-03 20:57 – Updated: 2026-07-06 13:57

Title

ext/openssl: Memory corruption in openssl_encrypt with AES-WRAP-PAD

Summary

In PHP versions 8.2.* before 8.2.32, 8.3.* before 8.3.32, 8.4.* before 8.4.23, 8.5.* before 8.5.8, the AES-WRAP-PAD algorithm implementation in OpenSSL extension contains a buffer allocation flaw. The output buffer for the AES key-wrap-with-padding operation is sized from the plaintext length without accounting for RFC 5649 expansion. This may cause OpenSSL to write beyond allocated memory, corrupting heap metadata and triggering application abort.

Severity

5.6 (Medium)
