Security Advisory

1) Buffer overflow

Severity: Low

CVSSv3: 4.5 [CVSS:3.0/AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:H/E:P/RL:O/RC:C] [PCI]

CVE-ID: CVE-2020-1283

CWE-ID: CWE-119 - Improper Restriction of Operations within the Bounds of a Memory Buffer

Exploit availability: Yes [Search exploit]

Description

The vulnerability allows a local user to perform denial of service (DoS) attack.

The vulnerability exists due to a boundary error when Windows improperly handles objects in memory. A local user can use a specially crafted application, or convince a user to open a specific file on a network share, trigger memory corruption and cause the system to stop responding.

Successful exploitation of this vulnerability may result in a denial of service (DoS) attack.

Mitigation

Install update from vendor's website.

2) Buffer overflow

Severity: Medium

CVSSv3: 7 [CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C] [PCI]

CVE-ID: CVE-2020-1300

CWE-ID: CWE-119 - Improper Restriction of Operations within the Bounds of a Memory Buffer

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when Windows fails to properly handle cabinet files. A remote authenticated attacker can convince a victim to either open a specially crafted cabinet file or spoof a network printer and trick a user into installing a malicious cabinet file disguised as a printer driver, leading to remote code execution.

Mitigation

Install updates from vendor's website.
