CVE-2010-3705
First published: Mon Oct 04 2010(Updated: )
Description of problem: When parsing a peer's supported HMAC authentication options in the sctp_auth_asoc_get_hmac() function, a malicious peer can craft their HMAC array in such a way as to cause memory corruption (out-of-bounds read followed by use of retrieved out-of-bounds data), which at the very least could cause a denial of service via kernel panic, and possibly worse. It appears this could be triggered remotely when connecting to a malicious peer, or locally by a user acting as both endpoints. In both cases, the "auth_enable" sysctl must be set in order to trigger the bug.
