Bug #69541 [NEW]: mktime() with date.timezone set crashes

From: kalle Operating system: PHP7 PHP version: master-Git-2015-04-28 (Git) Package: Date/time related Bug Type: Bug Bug description:mktime() with date.timezone set crashes Description: ------------ After the recent tzdb format change, then a simple call to mktime now crashes. Looking into it a tiny bit shows that the whole magic happens in read_location() (ext/date/lib/parse_tz.c), buffer[2] which is the length of the comments is passed through the timelib_conv_int() macro that then causes the number to be negative, thrus making malloc fail I did not test against the 5.x versions that was also affected by the db update, but I guess the same problem persists there. Test script: --------------- php -r "mktime();" <- No crash php -d date.timezone=CET -r "mktime();" <- Crash -- Edit bug report at https://bugs.php.net/bug.php?id=69541&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=69541&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=69541&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=69541&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=69541&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=69541&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=69541&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=69541&r=needscript Try newer version: https://bugs.php.net/fix.php?id=69541&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=69541&r=support Expected behavior: https://bugs.php.net/fix.php?id=69541&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=69541&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=69541&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=69541&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=69541&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=69541&r=dst IIS Stability: https://bugs.php.net/fix.php?id=69541&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=69541&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=69541&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=69541&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=69541&r=mysqlcfg
