EUVDB-ID: #VU70474
Risk: High
CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-47629
CWE-ID:
CWE-190 - Integer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in the CRL signature parser. A remote attacker can pass specially crafted data to the application, trigger an integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationInstall updates from vendor's website.

EUVDB-ID: #VU71332
Risk: Low
CVSSv3.1: 7.2 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:F/RL:O/RC:C]
CVE-ID: CVE-2023-22809
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: Yes
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists within the sudoedit (aka -e) feature due to insufficient validation of user-supplied input passed in the user-provided environment variables (SUDO_EDITOR, VISUAL, and EDITOR). The problem exists because a user-specified editor may contain a "--"
argument that defeats a protection mechanism, e.g., an EDITOR='vim --
/path/to/extra/file' value. A local user can append arbitrary entries to the list of files to process and escalate privileges on the system.
