Description
This security bulletin contains information about 1 security vulnerability.
1) Improper authentication (CVE-ID: CVE-2008-4576)
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.
