| Summary | 0000125: Crash with MAGIC_COMPRESS and magic_buffer | ||||
| Description | (I already reported this, but it does not appear in my list of submitted bugs here so re-submitting). With libmagic 5.25, running magic_buffer on the contents of a Microsoft Word .docx file and MAGIC_COMPRESS enabled produced a crash. For some reason I'm not able to capture a stack in gdb. This does not reproduce in 5.30, nor with magic_file. I'm reporting despite the fact that it's apparently fixed in case this is a security issue; 5.25 is in Ubuntu Xenial and that's supported for 5 more years. Original report here: https://github.com/ahupp/python-magic/issues/200 | ||||
| Steps To Reproduce | adam@gaba:~/file-5.25/src/.libs$ LD_LIBRARY_PATH=. PYTHONPATH=../../python python Python 2.7.13 (default, Sep 26 2018, 18:42:22) [GCC 6.3.0 20170516] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import magic >>> m=magic.open(magic.MAGIC_COMPRESS) >>> m.load('/home/adam/file-5.25/magic/magic.mgc') 0 >>> m.buffer(open('/home/adam/test.docx').read()) adam@gaba:~/file-5.25/src/.libs$ | ||||

The responsibility for fixing this should be with the xenial folks. They chose the version of file to support and the period of time to support it. They can always upgrade to a newer one or track or fix the bug themselves. |
