Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) 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.
