Description

This security bulletin contains information about 1 vulnerability.


1) Improper authentication (CVE-ID: CVE-2008-4576)

CWE-ID: CWE-287 - Improper Authentication

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


The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

sctp in Linux kernel before 2.6.25.18 allows remote attackers to cause a denial of service (OOPS) via an INIT-ACK that states the peer does not support AUTH, which causes the sctp_process_init function to clean up active transports and triggers the OOPS when the T1-Init timer expires.


Remediation

Install update from vendor's website.
