Update Summary
PHP 8.5.4 addresses multiple crashes, assertion failures, JIT and OpCache defects, extension errors, memory leaks, and compilation problems.
Update Details
Bug Fixes
- Fixed multiple Core crashes and assertion failures involving AArch64 LTO builds, preloaded constant AST closures, constant-expression
(unset)casts, lazy objects, Reflection lazy proxies, and hooked property operations. - Fixed JIT behavior when accessing null array keys and corrected OpCache JIT shared-memory handling on Solaris.
- Fixed DatePeriod state restoration with a null start and preserved precision for timezone offsets containing seconds.
- Fixed DOM Node property access errors that could incorrectly throw TypeError.
- Relaxed LDAP control argument validation so attributes can be unset with
ldap_modify(). - Prevented
mb_guess_encoding()crashes when given very large candidate-encoding lists. - Fixed OpenSSL memory leaks and error propagation, Curl length truncation, and several build-system and compilation issues.
