GNU gzip - News: gzip-1.4 released [stable/security]
gzip-1.4 released [stable/security]
Item posted by Jim Meyering <meyering> on Wed 20 Jan 2010 07:12:49 PM UTC.
This is to announce a stable release of the gzip compression tools.
The most important change is the one that addresses CVE-2010-0001,
mentioned in NEWS below.
http://www.gnu.org/software/gzip/
For a summary of changes and contributors, see:
http://git.sv.gnu.org/gitweb/?p=gzip.git;a=shortlog;h=v1.4
or run this command from a git-cloned gzip directory:
git shortlog v1.3.14..v1.4
Here are the compressed sources:
ftp://ftp.gnu.org/gnu/gzip/gzip-1.4.tar.gz (888KB)
ftp://ftp.gnu.org/gnu/gzip/gzip-1.4.tar.xz (600KB)
Here are the GPG detached signatures[*]:
ftp://ftp.gnu.org/gnu/gzip/gzip-1.4.tar.gz.sig
ftp://ftp.gnu.org/gnu/gzip/gzip-1.4.tar.xz.sig
To reduce load on the main server, use a mirror listed at:
http://www.gnu.org/order/ftp.html
[*] You can use either of the above signature files to verify that
the corresponding file (without the .sig suffix) is intact. First,
be sure to download both the .sig file and the corresponding tarball.
Then, run a command like this:
gpg --verify gzip-1.4.tar.gz.sig
If that command fails because you don't have the required public key,
then run this command to import it:
gpg --keyserver keys.gnupg.net --recv-keys B9AB9A16
and rerun the `gpg --verify' command.
This release was bootstrapped with the following tools:
Autoconf 2.65.23-13e35
Automake 1.11a
Gnulib v0.0-3341-gb4349b9

* Noteworthy changes in release 1.4 (2010-01-20) [stable]
** Bug fixes
gzip -d could segfault and/or clobber the stack, possibly leading to
arbitrary code execution. This affects x86_64 but not 32-bit systems.
This fixes CVE-2010-0001.
For more details, see http://bugzilla.redhat.com/554418
gzip -d would fail with a CRC error for some valid inputs.
So far, the only valid input known to exhibit this failure was
compressed "from FAT filesystem (MS-DOS, OS/2, NT)". In addition,
to trigger the failure, your memcpy implementation must copy in
the "reverse" order.
