Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Improper Certificate Validation
EUVDB-ID: #VU65760
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-26305
CWE-ID:
CWE-295 - Improper Certificate Validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to improper certificate validation when checking signed macro attached to the document. A remote attacker can trick the victim to open a specially crafted file, bypass implemented security restrictions and execute arbitrary code on the system.
Install updates from vendor's website.

2) Inadequate Encryption Strength
EUVDB-ID: #VU65767
Risk: Low
CVSSv3.1: 2.9 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-26306
CWE-ID:
CWE-326 - Inadequate Encryption Strength
Exploit availability: No
DescriptionThe vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to LibreOffice uses a weak initialization vector for encrypting passwords for web connections in the user’s configuration database. A local user can decrypt victim's password.

3) Inadequate Encryption Strength
EUVDB-ID: #VU65768
Risk: Low
CVSSv3.1: 2.9 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-26307
CWE-ID:
CWE-326 - Inadequate Encryption Strength
Exploit availability: No
DescriptionThe vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to LibreOffice uses a poor encoding of the master key for web connections in the user’s configuration database, resulting in weakening its entropy from 128 to 43 bits. A local user can decrypt victim's password. MitigationInstall updates from vendor's website.

4) Command Injection
EUVDB-ID: #VU68115
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-2022-3140
CWE-ID:
CWE-77 - Command injection
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.
The vulnerability exists due to improper input validation when parsing arguments for the "vnd.libreoffice.command'" URI scheme. A remote attacker can create a specially crafted document, trick the victim into opening it and execute internal macros with arbitrary arguments.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
