Date: Tue, 26 Aug 2008 23:25:48 +0800 From: Eugene Teo <eteo@...hat.com> To: oss-security@...ts.openwall.com Subject: CVE-2008-3526 Linux kernel sctp_setsockopt_auth_key() integer overflow An integer overflow flaw was found in the Linux kernel sctp_setsockopt_auth_key() function. The structure used for SCTP_AUTH_KEY option contains a length that needs to be verified to prevent integer overflow conditions. This affects kernel versions since 2.6.24-rc1. The proposed upstream commit is: 30c2235cbc477d4629983d440cdc4f496fec9246. Note that the SCTP-AUTH extension is now disabled by default since last week with upstream commit 5e739d17. I have allocated this CVE-2008-3526. Thanks, Eugene -- Eugene Teo / Red Hat Security Response Team
