EUVDB-ID: #VU59131
Risk: Low
CVSSv4.0: 1.9 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2013-4235
CWE-ID:
CWE-367 - Time-of-check Time-of-use (TOCTOU) Race Condition
Exploit availability: No
DescriptionThe vulnerability allows a local user to delete or modify arbitrary files on the system.
The vulnerability exists due to a race condition in shadow-utils when executing usermod/userdel operations. A local user with write access to the directory that is being moved or deleted by the usermod/userdel commands can modify or delete arbitrary files on the system.
Successful exploitation of the vulnerability may allow an attacker to corrupt arbitrary files on the system and perform a denial of service (DoS) attack.
Update the affected package shadow to the latest version.
