From: DelislMa@CollegeSherbrooke.qc.ca Operating system: Linux 2.1.126 PHP version: 3.0.5 PHP Bug Type: Misbehaving function Bug description: system() with a command containing a pipe: fails under safe mode In PHP 3.0.5 under Apache 1.3.3, I can't execute a system command containing a pipe, while in safe mode. In php3.ini: [safemode] safe_mode=1 safe_mode_exec_dir=/usr/local/php/safe ================================ In /usr/local/php/safe: lrwxrwxrwx 1 root apache 13 Nov 25 08:49 sort2 -> /usr/bin/sort lrwxrwxrwx 1 root apache 18 Nov 25 08:49 who2 -> /usr/local/bin/who ============================================ Trying this script: <html><body> <?php $safe_dir = "/usr/local/php/safe"; echo "<br>safe mode test1 <br>"; system("${safe_dir}/who2 | ${safe_dir}/sort2 -r"); echo "<br> safe mode test2 <br>"; system("${safe_dir}/who2"); ?> </body></html> When safe_mode=0, I see the output of tests 1 and 2. However, when safe_mode=1, test1 outputs nothing and test2 is ok.
