CVE-2017-9304 [HIGH] YARA vulnerabilities
Title: YARA vulnerabilities
Summary: Several security issues were fixed in YARA.
Kamil Frankowicz discovered that a number of YARA's functions
generated memory exceptions when processing specially crafted
rules or files. A remote attacker could possibly use these
issues to cause YARA to crash, resulting in a denial of
service. These issues only affected Ubuntu 16.04 LTS.
(CVE-2016-10211, CVE-2017-5923, CVE-2017-5924, CVE-2017-8294,
CVE-2017-8929, CVE-2017-9304, CVE-2017-9438, CVE-2017-9465)
Jurriaan Bremer discovered that YARA's yr_object_array_set_limit()
function could result in a heap buffer overflow when scanning
specially crafted .NET files. A remote attacker could possibly use
this issue to cause YARA to crash, resulting in a denial of service.
This issue only affected Ubuntu 16.0
