Synopsis: Moderate: gzip security update Advisory ID: RHSA-2010:0061-02 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2010-0061.html Issue date: 2010-01-20 CVE Names: CVE-2010-0001 =====================================================================
1. Summary:
An updated gzip package that fixes one security issue is now available for Red Hat Enterprise Linux 3, 4, and 5.
This update has been rated as having moderate security impact by the Red Hat Security Response Team.
2. Relevant releases/architectures:
Red Hat Desktop version 3 - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux Desktop version 4 - i386, x86_64 Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64 Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64
3. Description:
The gzip package provides the GNU gzip data compression program.
An integer underflow flaw, leading to an array index error, was found in the way gzip expanded archive files compressed with the Lempel-Ziv-Welch (LZW) compression algorithm. If a victim expanded a specially-crafted archive, it could cause gzip to crash or, potentially, execute arbitrary code with the privileges of the user running gzip. This flaw only affects 64-bit systems. (CVE-2010-0001)
Red Hat would like to thank Aki Helin of the Oulu University Secure Programming Group for responsibly reporting this flaw.
Users of gzip should upgrade to this updated package, which contains a backported patch to correct this issue.
4. Solution:
Before applying this update, make sure that all previously-released errata relevant to your system have been applied.
This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/docs/DOC-11259
5. Bugs fixed (http://bugzilla.redhat.com/):
554418 - CVE-2010-0001 gzip: (64 bit) Integer underflow by decompressing LZW format files
