Security Bulletin
This security bulletin contains information about 5 vulnerabilities.
1) Heap-based buffer over-read
EUVDB-ID: #VU9689
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-2017-9050
CWE-ID:
CWE-126 - Buffer over-read
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the xmlDictAddString function of XMLSoft libxml2 due to improper bounds checking in the dict.c code. A remote attacker can send a specially crafted request, trigger heap-based buffer over-read condition and cause the service to crash.
Successful exploitation of the vulnerability results in denial of service.

3) Stack-based buffer overflow
EUVDB-ID: #VU9691
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-2017-9048
CWE-ID:
CWE-121 - Stack-based buffer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the xmlSnprintfElementContent function of XMLSoft libxml2 due to improper bounds checking in the valid.c code. A remote attacker can send a specially crafted request, trigger stack-based buffer overflow condition and cause the service to crash.
Successful exploitation of the vulnerability results in denial of service.

4) Memory corruption
EUVDB-ID: #VU9687
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-2017-9047
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the xmlSnprintfElementContent function of XMLSoft libxml2 due to improper memory handling by the valid.c source code. A remote attacker can send a specially crafted XML file, trigger memory corruption and cause the service to crash.
Successful exploitation of the vulnerability results in denial of service.

5) 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.
