| Summary | 0013599: [git/master] VisItBridge GMVReader: segfault while reading GMV file with broken fromfile reference | ||||||||
| Description | Load the attached file "foo.gmv" by means of the VisItBridge GMVReader in a nightly build. => segfault due to read attempt from NULL pointer with fscanf(). Reason behind is that the program logic in gmvread.c is in no way prepared to keep going in case of a broken fromfile reference. Originally, gmvread.c did a 'exit(0)' in that case, but that got commented out when adding to the VisIt source tree. I have a patch to resolve this, but it requires other patches to gmvread.c to be applied first. | ||||||||

commit 0909dcb99dcdc008a937d22ec4fcb2d75e9b23bb Author: Sven Buijssen <sven.buijssen@tu-dortmund.de> Date: Fri Nov 2 12:17:53 2012 +0100 BUG 0013599. Fixed segfault while reading file with broken fromfile reference gmvread.c traditionally used to 'exit(0)' if a file referred to in a GMV file did not exist. Simply commenting out the 'exit(0)' statement (the strategy pursued in VisIt currently) led subsequently to attempts of reading from NULL stream with fscanf() and fread(). |
