#19649 [Com]: Nested [] in browscap.ini cause PHP to crash

ID: 19649 Comment by: bcash at alpineinternet dot com Reported By: mark at quarella dot co dot uk Status: Closed Bug Type: Reproducible crash Operating System: Linux PHP Version: 4.3.0-dev Assigned To: zeev New Comment: Found a similar cause for this problem: -- snip from browscap.ini -- [Mozilla/5.0 (compatible; Yahoo! Slurp; http://help.yahoo.com/help/us/ysearch/slurp)] parent=Yahoo browser=Yahoo! Slurp AK=False SK=False -- end snip -- The "!" in the browser key is causing this problem on my system. The "!" in the section name is ok. When I remove the bang from the browser key, the browser.ini is able to load properly. (This is php 4.3.4 on FreeBSD) Previous Comments: ------------------------------------------------------------------------ [2003-01-24 09:04:41] ronstk at worldonline dot nl From the browsecap.ini included v4.2.3. [AE/2.1 (linux)] browser=AE/2.1(Linux) ;browser="AE/2.1(Linux)" version=2.1 gives me the error in dosbox: PHP: Error parsing E:\Iservers\PHP\browscap\browscap.ini on line 8206. The fault here are the '(' and ')' This is.nt working with 4.3.x also ------------------------------------------------------------------------ [2002-10-14 13:23:44] iliaa@php.net This bug has been fixed in CVS. In case this was a PHP problem, snapshots of the sources are packaged every three hours; this change will be in the next snapshot. You can grab the snapshot at http://snaps.php.net/. In case this was a documentation problem, the fix will show up soon at http://www.php.net/manual/. In case this was a PHP.net website problem, the change will show up on the PHP.net site and on the mirror sites in short time. Thank you for the report, and for helping us make PHP better. ------------------------------------------------------------------------ [2002-10-01 18:00:17] iliaa@php.net verified & updated version. The problem occurs because 'arg2' passed to php_browscap_parser_cb() is NULL and there are no checks for it, which causes Z_STRLEN_P(arg2) to core. ------------------------------------------------------------------------ [2002-09-28 10:58:17] mark at quarella dot co dot uk An entry in browscap.ini similar to the following: [Mozilla/4.76 (Macintosh;US;PPC) Opera 4.? [en]] .. will cause Apache/PHP to fail to start (segmentation fault) due to the nested [] symbols. The following complete browscap.ini would be enough to reproduce this: [Opera 4.0] [Mozilla/4.76 (Macintosh;US;PPC) Opera 4.? [en]] parent=Opera 4.0 platform=MacPPC Interestingly, without a correctly formed entry on the first line PHP reports a warning instead. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=19649&edit=1
