Description

This security bulletin contains information about 2 vulnerabilities.


1) Time-of-check Time-of-use (TOCTOU) Race Condition (CVE-ID: CVE-2013-4235)

CWE-ID: CWE-367 - Time-of-check Time-of-use (TOCTOU) Race Condition

CVSSv4: 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


The 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.


2) Insufficient Entropy (CVE-ID: CVE-2017-2626)

CWE-ID: CWE-331 - Insufficient Entropy

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local authenticated user to gain access to sensitive information.

It was discovered that libICE before 1.0.9-8 used a weak entropy to generate keys. A local attacker could potentially use this flaw for session hijacking using the information available from the process list.
