Seg. Fault

[plutec]

I'm not sure if this problem is for Yara or Yara-python.

When you compile several rules from a dictionary, it produce a seg.fault. Bellow you can follow a python code to reproduce it.

import yara
rules_dict = dict()
content = 'import "androguard"\r\nimport "file"\r\nimport "cuckoo"\r\n\r\n\r\nrule koodous : official\r\n{\r\n\tmeta:\r\n\t\tdescription = "This rule detects the koodous application, used to show all Yara rules potential"\r\n\t\tsample = "e6ef34577a75fc0dc0a1f473304de1fc3a0d7d330bf58448db5f3108ed92741b"\r\n\r\n\tstrings:\r\n\t\t$a = {63 6F 6D 24 6B 6F 6F 64 6F 75 73 24 61 6E 64 72 6F 69 64}\r\n\r\n\tcondition:\r\n\t\tandroguard.package_name("com.koodous.android") and\r\n\t\tandroguard.app_name("Koodous") and\r\n\t\tandroguard.activity(/Details_Activity/i) and\r\n\t\tandroguard.permission(/android.permission.INTERNET/) and\r\n\t\tandroguard.certificate.sha1("8399A145C14393A55AC4FCEEFB7AB4522A905139") and\r\n\t\tandroguard.url(/koodous\\.com/) and\r\n\t\tnot file.md5("d367fd26b52353c2cce72af2435bd0d5") and \r\n\t\t$a and\r\n\t\tcuckoo.network.dns_lookup(/settings.crashlytics.com/) //Yes, we use crashlytics to debug our app!\r\n\t\t\r\n}\r\n'
for i in range(1000):
    rules_dict['rule_%d'%i] = content

yara.compile(sources=rules_dict)
