EUVDB-ID: #VU95585

Risk: Low

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2006-1527

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

The SCTP-netfilter code in Linux kernel before 2.6.16.13 allows remote attackers to trigger a denial of service (infinite loop) via unknown vectors that cause an invalid SCTP chunk size to be processed by the for_each_sctp_chunk function. Upgrade to Linux Kernel version 2.6.16.13 : http://www.kernel.org/

Mitigation

Install update from vendor's repository.
