Bug #64314 [NEW]: imagettfbbox loads wrong fontname if using ../ and underscore in font name

From: ctcrmcou at opm dot gov Operating system: W7 PHP version: Irrelevant Package: GD related Bug Type: Bug Bug description:imagettfbbox loads wrong fontname if using ../ and underscore in font name Description: ------------ Assuming a subdirectory named "fonts" contains 30 fonts named font_1.ttf - font_30.ttf, calling imagettfbox with a fontname such as "../fonts/font_10.ttf" loads incorrect font, the number part is somehow being altered and the wrong font is loading. Somehow the combination of ../ and _ in the finename param are screwing things up. This is not a file/font not found error. This is the font that loads font_13.ttf is actually loading font_14.ttf, or font_28.ttf is loading font_10.ttf. I can only guess the underscore is changing the meaning of the number or the number is being converted. Test script: --------------- Works: $box=imagettfbbox(100,0,"fonts/font_10.ttf","some text"); Doesn't work (wrong font loads): $box=imagettfbbox(100,0,"../fonts/font_10.ttf","some text"); Workaround 1: remove underscore from font names $box=imagettfbbox(100,0,"../fonts/font10.ttf","some text"); Workaround 2: move app that loads font to higher directory level (no ../ in path) $box=imagettfbbox(100,0,"fonts/font_10.ttf","some text"); -- Edit bug report at https://bugs.php.net/bug.php?id=64314&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=64314&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=64314&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=64314&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=64314&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=64314&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=64314&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=64314&r=needscript Try newer version: https://bugs.php.net/fix.php?id=64314&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=64314&r=support Expected behavior: https://bugs.php.net/fix.php?id=64314&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=64314&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=64314&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=64314&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=64314&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=64314&r=dst IIS Stability: https://bugs.php.net/fix.php?id=64314&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=64314&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=64314&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=64314&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=64314&r=mysqlcfg
