Red Hat Bugzilla – Bug 204460
CVE-2006-4535 Regression with fix for SCTP abort issue
Last modified: 2012-05-19 19:35:41 EDT
From Sridhar Samudrala:
With the recent fix, the callers of sctp_primitive_ABORT() need to create an
ABORT chunk and pass it as an argument rather than msghdr that was passed earlier.
This is a regression with bug 202122 (CVE-2006-3745).
The regression causes a panic if an SCTP socket has SO_LINGER set with a linger
value of 0 and it is closed.
Looks pretty obvious. Let me smoke test it quick and I'll post it.
