Security Bulletin

This security bulletin contains information about 6 vulnerabilities.

1) Use-after-free

EUVDB-ID: #VU20898

Risk: High

CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-10996

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error when processing CD31 files. A remote attacker can trick a victim to open a specially crafted file, that can reference memory after it has been freed and execute arbitrary code on the target system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.

Mitigation

Install updates from vendor's website.

2) Out-of-bounds read

EUVDB-ID: #VU20900

Risk: Low

CVSSv3.1: 3.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-10978

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a remote attacker to disclose sensitive information on the target system.

The vulnerability exists due to a boundary error when processing CD31 files. A remote attacker can trick a victim to open a specially crafted file, trigger out-of-bounds read error and disclose sensitive information.

3) Untrusted Pointer Dereference

EUVDB-ID: #VU20902

Risk: High

CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-10984

CWE-ID: CWE-822 - Untrusted Pointer Dereference

Exploit availability: No

Description

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

The vulnerability exists due to lack of validation of a user-supplied value prior to dereferencing it as a pointer when parsing CD3 and CD31 files. A remote attacker can trick a victim to open a specially crafted file, that causes the program to mishandle pointers and execute arbitrary code on the target system.
