Announcing NetBSD 4.0.1
The NetBSD Project is pleased to announce that update 4.0.1 of the NetBSD operating system is now available. NetBSD 4.0.1 is the first security/critical update of the NetBSD 4.0 release branch. This represents a selected subset of fixes deemed critical in nature for stability or security reasons, no new features have been added.
NetBSD 4.0.1 runs on 54 different system architectures featuring 17 machine architectures across 17 distinct CPU families, and is being ported to more. The NetBSD 4.0.1 release contains complete binary releases for 51 different machine types, with the platforms amigappc, bebox and ews4800mips released in source form only. Complete source and binaries for NetBSD 4.0.1 are available for download at many sites around the world. A list of download sites providing FTP, AnonCVS, SUP, and other services is provided at the end of this announcement; the latest list of available download sites may also be found at http://www.NetBSD.org/mirrors/. We encourage users who wish to install via a CD-ROM ISO image to download via BitTorrent by using the torrent files supplied in the ISO image area. A list of hashes for the NetBSD 4.0.1 distribution has been signed with the well-connected PGP key for the NetBSD Security Officer: ftp://ftp.NetBSD.org/pub/NetBSD/security/hashes/NetBSD-4.0.1_hashes.asc
Please note that all fixes in security/critical updates (i.e., NetBSD 4.0.1, 4.0.2, etc) are cumulative, so the latest update contains all such fixes since the corresponding minor release. These fixes will also appear in future minor releases (i.e., NetBSD 4.1, 4.2, etc), together with other less-critical fixes and feature enhancements.
NetBSD is free. All of the code is under non-restrictive licenses, and may be used without paying royalties to anyone. Free support services are available via our mailing lists and website. Commercial support is available from a variety of sources; some are listed at http://www.NetBSD.org/gallery/consultants.html. More extensive information on NetBSD is available from our website:
The complete list of changes can be found in the CHANGES-4.0.1 file in the top level directory of the NetBSD 4.0.1 release tree. A shortened list is as follows:
- NetBSD-SA2008-004, multiple issues (CVE-2008-1372 and CVE-2005-0953), has been fixed by upgrading to bzip2 to 1.0.5
- NetBSD-SA2008-005, OpenSSH Multiple issues (CVE-2008-1483 and CVE-2008-1657), has been fixed by applying patches from upstream.
- NetBSD-SA2008-006, integer overflow in strfmon(3) function (CVE-2008-1391), has been fixed.
- NetBSD-SA2008-008, OpenSSL Montgomery multiplication (CVE-2007-3108), has been fixed.
BIND cache poisoning (CVE-2008-1447 and CERT VU#800113),
has been fixed by updating BIND to 9.4.2-P2.
Note there are two related changes to this advisory:
- The default behavior of ipfilter's Port Address Translation has been changed to using random port allocation rather than sequential mappings, to avoid decreasing the randomness of source ports used for DNS queries which affects the BIND cache poisoning problem.
- A `
query-source' statement, which could allow the BIND cache poisoning attack, has been commented out in the default named.conf(5) file.
- NetBSD-SA2008-010, malicious PPPoE discovery packet can overrun a kernel buffer (CVE-2008-3584), has been fixed.
- NetBSD-SA2008-011, ICMPv6 MLD query (CVE-2008-2464), has been fixed.
- NetBSD-SA2008-012, Denial of Service issues in racoon(8) (CVE-2008-3652), has been fixed by upgrading ipsec-tools to release 0.7.1. Note this also fixes CVE-2008-3651.
- NetBSD-SA2008-013, IPv6 Neighbor Discovery Protocol (CVE-2008-2476), has been fixed.
- NetBSD-SA2008-014, Cross-site request forgery in ftpd(8) (CVE-2008-4247), has been fixed.
- NetBSD-SA2008-015, ICMPv6 Packet Too Big messages (CVE-2008-3530), has been fixed.
Note: NetBSD-SA2008-007 and advisories prior to NetBSD-SA2008-004 don't affect NetBSD 4.0.
- Fix a buffer overrun which could crash a FAST_IPSEC kernel.
- tcpdump(8): fix CVE-2007-1218, CVE-2007-3798 and CAN-2005-1278 in base-tcpdump.
- Fix a buffer overflow of PCF font parser in X11 libXfont library (CVE-2008-0006).
- Fix a buffer overflow of Tektronix Hex Format support in binutils (CVE-2006-2362).
- machfb(4) and voodoofb(4): introduce two missing KAUTH_GENERIC_ISSUSER checks in the mmap(2) code.
- Update root.cache to 2008020400 version.
- Fix IP packet forwarding code to make sure to send a reasonable fragment size when IPsec is configured.
- Fix a bug in TCP SACK code which causes data corruption.
- Fix an rc.d(8) script for amd(8) not to shutdown gracefully since it seems to cause problems for more people than the old (also broken) behavior.
- ftpd(8): fix and reorganize PAM support.
- Pthread support of BIND has been disabled for future binary compatibility after removal of the scheduler activations.
- Fix coredump of gdtoa (conversion between binary floating-point and ASCII string) functions on out of memory conditions.
- Disable a NULL pointer check in zlib for standalone programs. This fixes errors on loading a gzipped kernel (including installation kernels) on several ports (news68k etc.) whose kernels are loaded at address zero.
- awk(1): bring back an accidentally removed fix to allow escape of a newline in string literals.
- fix compilation of native sh3 gcc on 64-bit build machines
- fix an internal compiler error on compiling m68k softfloat or m68010 targets on 64-bit build machines.
-h' option (suppress filenames on output when multiple files are searched) actually work.
- Fix parallel build failure on building hpcarm, hpcmips and hpcsh releases.
- acorn32: fix a bootloader problem on some RiscPCs.
- add a workaround to avoid panic on probing a multi function PCI device on Qube's PCI slot
- fix a bug in the interrupt handler which causes network freeze if more than one interfaces are used.
- hppa: fix potential kernel / userland memory corruption in copyinstr(9) and copyoutstr(9).
fix a bug in
locore.swhich causes unexpected behavior.
- sun3: fix a bug which might cause an occasional panic during boot.
- vax: make syscall handler use proper copyin(9) function on parsing syscall args.
