Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
EUVDB-ID: #VU8113
Risk: Low
CVSSv3.1:
CVE-ID: CVE-2017-7539
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on a targeted system.
The weakness exists due to an assertion failure when handling malicious input. A remote attacker can submit a specially crafted data during initial connection negotiation and cause the qemu-nbd server to stop functioning.
Successful exploitation of the vulnerability results in denial of service.
Install update from vendor's website.

CVSSv3.1:
CVE-ID: CVE-2017-15118
CWE-ID:
CWE-121 - Stack-based buffer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists in the network block device (NBD) server implementation due to stack-based buffer overflow when handling malicious input. A remote unauthenticated attacker can send a large export-name request, trigger memory corruption and cause the service to crash or execute arbitrary code with elevated privileges.
MitigationUpdate to version 2.11 or later.
