Red Hat Security Advisory: php:7.4 security update
PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server. Security Fix(es): * php: Leak partial content of the heap through heap buffer over-read in mysqlnd (CVE-2024-8929) * php: Single byte overread with convert.quoted-printable-decode filter (CVE-2024-11233) * php: Configuring a proxy in a stream context might allow for CRLF injection in URIs (CVE-2024-11234) * php: Header parser of http stream wrapper does not handle folded headers (CVE-2025-1217) * php: Stream HTTP wrapper header check might omit basic auth header (CVE-2025-1736) * php: Streams HTTP wrapper does not fail for headers with invalid name and no colon (CVE-2025-1734) * php: libxml streams use wrong content-type header when requesting a redirected resource (CVE-2025-1219) * php: Stream HTTP wrapper truncates redirect location to 1024 bytes (CVE-2025-1861) * php: pgsql extension does not check for errors during escaping (CVE-2025-1735) * php: NULL Pointer Dereference in PHP SOAP Extension via Large XML Namespace Prefix (CVE-2025-6491) * php: PHP Hostname Null Character Vulnerability (CVE-2025-1220) * php: heap-based buffer overflow in array_merge() (CVE-2025-14178) * php: PHP: Information disclosure via getimagesize() function when reading multi-chunk images (CVE-2025-14177) 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.
AI Analysis
Technical Summary
This Red Hat security advisory addresses multiple vulnerabilities in PHP 8.1, including CVE-2024-8929 which involves a heap buffer over-read in the mysqlnd extension causing partial heap content leakage. Other issues include a single byte overread in the convert.quoted-printable-decode filter (CVE-2024-11233), CRLF injection in URIs when configuring a proxy in a stream context (CVE-2024-11234), and several HTTP stream wrapper flaws affecting header parsing, basic auth header omission, invalid header handling, incorrect content-type headers on redirects, and truncation of redirect locations (CVE-2025-1217, CVE-2025-1736, CVE-2025-1734, CVE-2025-1219, CVE-2025-1861). The advisory applies to PHP 8.1 packages on Red Hat Enterprise Linux 9 and related variants. Red Hat has released updated packages to fix these vulnerabilities.
Potential Impact
The vulnerabilities collectively may allow information leakage through heap buffer over-read, improper decoding leading to data exposure, injection of CRLF sequences in URIs potentially affecting HTTP request integrity, and incorrect handling of HTTP headers that could impact authentication and redirection behavior. The overall security impact is rated moderate by Red Hat Product Security. No known exploits in the wild have been reported at this time.
Mitigation Recommendations
Red Hat has released updated PHP 8.1 packages for Red Hat Enterprise Linux 9 that address these vulnerabilities. Users should apply the official security update as detailed in the Red Hat advisory RHSA-2025:4263. For update instructions, refer to https://access.redhat.com/articles/11258. No additional mitigations are specified or required beyond applying the official patch.
