Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Input validation error
EUVDB-ID: #VU71332
Risk: Low
CVSSv4.0: 8.5 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Clear]
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.

2) Input validation error
EUVDB-ID: #VU65855
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-2022-33070
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input within the parse_tag_and_wiretype() function in protobuf-c/protobuf-c.c. A remote attacker can trick the victim to open a specially crafted file, cause an invalid arithmetic shift and perform a denial of service (DoS) attack.
