As the announcement on
ftp://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2008-003.txt.asc and
http://www.netbsd.org/support/security/patches-3.1.1.html
1. This security problem affected NetBSD-3.1 release and did not affect
NetBSD-3.1.1 release.
2. NetBSD-3.1.2 which will be released in the future contains
the fixed.
3. It can be fixed by fixing sys/netinet6/ipcomp_input.c
However, I found the source file sys/netinet6/ipcomp_input.c in
NetBSD-3.1.1 release is same to the file in the NetBSD-3.1 release,
and is different from the file in the source tree of NetBSD-3-1 branch.
Does it mean that the file in NetBSD-3.1 is not fixed and the
file in the source tree of NetBSD-3-1 branch is fixed?
If it is true, why NetBSD-3.1 release is affected but NetBSD-3.1.1
release is not?
Thank you.
