Description

The CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS7:CLSA-2026:1786448352 advisory.

 - Improper escaping of backslashes in attacker-provided parameters would allow for trivial SQL injection in PHP versions from 8.2.* before 8.2.33, from 8.3.* before 8.3.33, from 8.4.* before 8.4.24, and from 8.5.* before 8.5.9. (CVE-2026-17543)

 - Circular symbolic links in phar archives could lead to unbounded recursion, exhausting the C stack and crashing the PHP process, in PHP versions from 8.2.* before 8.2.33, from 8.3.* before 8.3.33, from 8.4.* before 8.4.24, and from 8.5.* before 8.5.9. (CVE-2026-7260)

 - NOTE: Fixed by: https://github.com/php/php-src/commit/b590f0380fda26ed180874a0255f0be078434315 (php-8.4.24)DEBIANBUG: [1143152] (CVE-2026-9672) (CVE-2026-9672)
