From: Operating system: Windows Server 2008 R2 x64 PHP version: 5.3.9 Package: Unknown/Other Function Bug Type: Bug Bug description:null pointer dereference in php_win32_free_rng_lock()
Description: ------------ If php_win32_get_random_bytes() has never been called, then this line of code: + CryptReleaseContext(hCryptProv, 0); passes a null pointer, resulting in a C0000005 exception in CryptReleaseContext(). This line should be preceded by: if (has_crypto_ctx) This was specifically tested with the windows.php.net 32-bit TS build running on 64-bit Windows. I do not know how it behaves in other configurations. Test script: --------------- I do not have a short test case, but the bug is pretty obvious. -- Edit bug report at https://bugs.php.net/bug.php?id=60895&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=60895&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=60895&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=60895&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=60895&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=60895&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=60895&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=60895&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=60895&r=needscript Try newer version: https://bugs.php.net/fix.php?id=60895&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=60895&r=support Expected behavior: https://bugs.php.net/fix.php?id=60895&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=60895&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=60895&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=60895&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=60895&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=60895&r=dst IIS Stability: https://bugs.php.net/fix.php?id=60895&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=60895&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=60895&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=60895&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=60895&r=mysqlcfg
