Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
EUVDB-ID: #VU72719
Risk: Low
CVSSv4.0: 5.9 [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:U/U:Clear]
CVE-ID: CVE-2023-27320
CWE-ID:
CWE-415 - Double Free
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error when matching a sudoers rule that contains a per-command chroot directive (CHROOT=dir). A local user can trigger a double free error and execute arbitrary code with elevated privileges.

EUVDB-ID: #VU74196
Risk: Low
CVSSv4.0: 5.9 [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:U/U:Clear]
CVE-ID: CVE-2023-28486
CWE-ID:
CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
Exploit availability: No
DescriptionThe vulnerability allows a local user to execute arbitrary shell commands on the target system.
The vulnerability exists due to improper input validation when processing control characters in the log messages. A local user can inject specially crafted characters to the log messages and execute arbtirary OS commands on the system when the command is executed from the log (e.g. via the "sudoreplay -l").
