Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Out-of-bounds read
EUVDB-ID: #VU14608
Risk: Low
CVSSv3.1: 3 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L/E:P/RL:O/RC:C]
CVE-ID: CVE-2018-16429
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to cause DoS condition on the target system.
The vulnerability exists due to out-of-bounds read vulnerability in g_markup_parse_context_parse() in gmarkup.c, related to utf8_str(). A local attacker can execute a specially crafted application or file that submits malicious input and cause the service to crash.

Q & A
Can this vulnerability be exploited remotely?
No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability. However, proof of concept for this vulnerability is available.
2) Null pointer dereference
EUVDB-ID: #VU13949
Risk: Low
CVSSv3.1: 4.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:P/RL:O/RC:C]
CVE-ID: CVE-2018-14404
CWE-ID:
CWE-476 - NULL Pointer Dereference
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists in the xmlXPathCompOpEval() function, as defined in the path.c source code file due to improper parsing of invalid XPath expressions in the XPATH_OP_AND and XPATH_OP_OR cases. A remote attacker can send a specially crafted request that submits malicious input to an application that is using the affected library, trigger a NULL pointer dereference and cause the application to crash.

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability. However, proof of concept for this vulnerability is available.
3) XML External Entity injection
EUVDB-ID: #VU31830
Risk: Low
CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2016-9318
CWE-ID:
CWE-611 - Improper Restriction of XML External Entity Reference ('XXE')
Exploit availability: No
DescriptionThe vulnerability allows a local non-authenticated attacker to execute arbitrary code.
libxml2 2.9.4 and earlier, as used in XMLSec 1.2.23 and earlier and other products, does not offer a flag directly indicating that the current document may be read but other files may not be opened, which makes it easier for remote attackers to conduct XML External Entity (XXE) attacks via a crafted document.

4) NULL pointer dereference
EUVDB-ID: #VU20339
Risk: Low
CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-8936
CWE-ID:
CWE-476 - NULL Pointer Dereference
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error when processing authenticated mode 6 packets. A remote attacker can send malicious authenticated mode 6 (ntpq) packet from a permitted network address, trigger a NULL pointer dereference error and crash ntpd.
