Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Integer overflow (CVE-ID: CVE-2019-9278)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow. A remote attacker can pass specially crafted data to the application, trigger integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) Out-of-bounds read (CVE-ID: CVE-2020-0093)
The vulnerability allows a local user to gain access to potentially sensitive information.
