Description
This security bulletin contains information about 3 vulnerabilities.
1) Memory corruption (CVE-ID: CVE-2018-7714)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote unauthenticated attacker to cause DoS condition on the target system.
The weakness exists in the validateInputImageSize function due to boundary error. A remote attacker can trigger an assertion failure and cause the service to crash.
