ID: 12141 Updated by: thies Reported By: [EMAIL PROTECTED] Old Status: Open Status: Closed Bug Type: Reproducible crash Operating System: RedHat Linux 7.1 (Intel) PHP Version: 4.0.6 New Comment: fixed in CVS Previous Comments: ------------------------------------------------------------------------ [2001-07-13 09:08:26] [EMAIL PROTECTED] I have one PCD (Kodak PhotoCD) file which crashes PHP when I run iptcparse on its contents. The error message is "FATAL: emalloc(): Unable to allocate -4095 bytes". Unfortunately, I wasn't able to produce a core file (probably too dumb to configure with --enable-debug). PHP was configured "plain" (just "./configure", "make", "make install"). I can reproduce this crash with PHP 4.0.2-dev and 3.0.13-dev (error message here: "FATAL: emalloc(): Unable to allocate 4294963201 bytes") under Solaris, and with an older PHP 4 under RedHat Linux 6.2. Hundreds of other PCD files work fine, some of them bigger than my example file. You can download this PCD file from http://www.digicol.de/crash.html (it's nearly 5 MB). This is how you can reproduce the crash: ============================================== [tim@dhcp5 tim]$ ll insgesamt 7896 -rw-rw-r-- 1 tim tim 4898816 Jun 22 11:48 crash.pcd -rw-rw-r-- 1 tim tim 510 Jun 22 12:06 iptcparse-crash.php [tim@dhcp5 tim]$ cat iptcparse-crash.php <?php if (! isset($argv[ 1 ])) { echo "Usage: php iptcparse-crash.php <filename>\n"; exit; } $filename = $argv[ 1 ]; $buffer = ""; getimagesize($filename,&$info); if (isset($info[ "APP13" ])) $buffer = $info[ "APP13" ]; else { $fp = fopen($filename,"r"); if ($fp) { $buffer = fread($fp,filesize($filename)); fclose($fp); } } $ok = 0; if ($buffer != "") { echo "before iptcparse() ...\n"; $iptc = iptcparse($buffer); echo "... after iptcparse()\n"; } ?> [tim@dhcp5 tim]$ php -v 4.0.6 [tim@dhcp5 tim]$ php -q iptcparse-crash.php crash.pcd before iptcparse() ...
