Bug #76068 [NEW]: parse_ini_string fails to parse "[foo]\nbar=1|>baz" with segfault

From: madboyka at yahoo dot com Operating system: Windows 10 PHP version: 7.2.3 Package: Filesystem function related Bug Type: Bug Bug description:parse_ini_string fails to parse "[foo]\nbar=1|>baz" with segfault Description: ------------ Trying to parse the value "[foo]\nbar=1|>baz" with process_sections = true and scanner_mode = INI_SCANNER_TYPED causes a segmentation fault in the php process. Looks like PHP sees the | as a logical operator and tries to do something with it. Doesn't matter whether parse_ini_string or parse_ini_file is used. I tried this on: Windows 10 with PHP 7.2.3 Ubuntu 16.04 with PHP 7.1.14-1+ubuntu16.04.1+deb.sury.org+1 CentOS 7.4.1708 with PHP 7.1.14 Test script: --------------- parse_ini_string("[foo]\nbar=1|>baz",true, \INI_SCANNER_TYPED); Expected result: ---------------- the code should run without errors and return ['foo'=> ['bar' => '1|>baz']] Actual result: -------------- produces segmentation fault -- Edit bug report at https://bugs.php.net/bug.php?id=76068&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=76068&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=76068&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=76068&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=76068&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=76068&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=76068&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=76068&r=needscript Try newer version: https://bugs.php.net/fix.php?id=76068&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=76068&r=support Expected behavior: https://bugs.php.net/fix.php?id=76068&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=76068&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=76068&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=76068&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=76068&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=76068&r=dst IIS Stability: https://bugs.php.net/fix.php?id=76068&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=76068&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=76068&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=76068&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=76068&r=mysqlcfg
