ID: 10324 Updated by: derick Reported By: kpw@jump9.com Old-Status: Open Status: Assigned Bug Type: Reproducible crash Operating system: PHP Version: 4.0.6 Assigned To: derick Comments: Assigning to myself Previous Comments: --------------------------------------------------------------------------- [2001-07-03 22:51:56] kpw@jump9.com Here's the link to a script that exhibits this problem 100% of the time on my PPC/YellowDog server as well as a production machine at phpwebhosting.com: http://www.jump9.com/_testcrypt.txt I've tried this under several version of php (including the current 4.0.6) as well as with every available release of libmcrypt (2.4.7-2.4.15) all without effect. Given that I have the same problem on a production webserver at phpwebhosting as I do on my own homemade PPC linux box I'm guessing this is real problem... Any thoughts would be greatly appreciated... kpw --------------------------------------------------------------------------- [2001-07-03 11:28:04] kpw@jump9.com Here's an example: If encrypt the string "Reed, Phyllis" with the key "70094cc48e1a23bf6fec60c2db6e4b71" using blowfish in CBC mode mycrypt will seg fault. However, if I change the string to "Reed,Phyllis" (no space) everything's fine. Removing a chacter from the end (""Reed, Phylli") doesn't fix the problem though, so it's apparently not length related. Very strange indeed... kpw --------------------------------------------------------------------------- [2001-07-03 10:48:42] kpw@jump9.com Hi, This still seems to be a problem in 4.0.6. I'm pretty sure that it is caused by specific strings being passed into mycrypt, however, I'm not sure what string characteristics cause the problem. kpw --------------------------------------------------------------------------- [2001-05-27 19:27:02] sniper@php.net Should be fixed in CVS now. Fix will be in PHP 4.0.6. If this happens with it too, reopen this bug report. --Jani --------------------------------------------------------------------------- [2001-04-14 09:54:47] kpw@jump9.com here's the back trace (again without db symbols) of the crash when it happens after my script has completed execution: Program received signal SIGSEGV, Segmentation fault. 0xfe21138 in chunk_free (ar_ptr=0xfebb380, p=0x101f03d8) at malloc.c:3111 3111 malloc.c: No such file or directory.
