Description

This security bulletin contains information about 1 vulnerability.


1) Improper access control (CVE-ID: CVE-2006-1856)

CWE-ID: CWE-284 - Improper Access Control

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


The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

Certain modifications to the Linux kernel 2.6.16 and earlier do not add the appropriate Linux Security Modules (LSM) file_permission hooks to the (1) readv and (2) writev functions, which might allow attackers to bypass intended access restrictions.


Remediation
