Bug #18285: Memory Corruption with LANG and Safe Mode

From: ilia@prohost.org Operating system: Linux 2.4.17 PHP version: 4.2.1 PHP Bug Type: Scripting Engine problem Bug description: Memory Corruption with LANG and Safe Mode While trying to make a directory on a system with safe_mode enabled and LANG enviroemnt variable fi_FI@euro I came across the problem that is best demonstrated by the script below: <?php $src = '/dir/another/dir2/src'; if( !is_dir($src) ) { echo "no dir $src<br>n"; if( !@mkdir($src, 0755) ) { echo "cannot make dir: $src<Br>n"; } } ?> On the 2nd echo $src string is corrupted, the last / is replaced with a special character, which Mozilla displayes as a square. If mkdir($src, 0755) is replaced with mkdir($src.'', 0755) the memory corruption goes away. -- Edit bug report at http://bugs.php.net/?id=18285&edit=1 -- Fixed in CVS: http://bugs.php.net/fix.php?id=18285&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=18285&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=18285&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=18285&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=18285&r=support Expected behavior: http://bugs.php.net/fix.php?id=18285&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=18285&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=18285&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=18285&r=globals
