1) Buffer overflow
EUVDB-ID: #VU21683
Risk: Medium
CVSSv4.0: 4.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2019-1343
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform denial of service (DoS) attack.
The vulnerability exists due to a boundary error when processing certain files. A remote attacker can trick a victim to open a specially crafted file from a remote location, trigger memory corruption and cause the system to stop responding.
Successful exploitation of this vulnerability may result in a denial of service (DoS) attack.
MitigationInstall update from vendor's website.

4) Input validation error
EUVDB-ID: #VU21688
Risk: Low
CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
