Updated unzip packages that fix two security issues and various bugs are now available. A race condition was found in Unzip. Local users could use this flaw to modify permissions of arbitrary files via a hard link attack on a file while it was being decompressed (CVE-2005-2475). - --------------------------------------------------------------------- Red Hat Security Advisory Synopsis: Low: unzip security and bug fix update Advisory ID: RHSA-2007:0203-02 Advisory URL: https://access.redhat.com/errata/RHSA-2007:0203.html Issue date: 2007-05-01 Updated on: 2007-05-01 Product: Red Hat Enterprise Linux Keywords: large file toctou CVE Names: CVE-2005-2475 CVE-2005-4667 - ---------------------------------------------------------------------1. Summary: Updated unzip packages that fix two security issues and various bugs are now available. This update has been rated as having low security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux Desktop version 4 - i386, x86_64 Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64 3. Problem description: The unzip utility is used to list, test, or extract files from a zip archive. A race condition was found in Unzip. Local users could use this flaw to modify permissions of arbitrary files via a hard link attack on a file while it was being decompressed (CVE-2005-2475) A buffer overflow was found in Unzip command line argument handling. If a user could be tricked into running Unzip with a specially crafted long file name, an attacker could execute arbitrary code with that user's privileges. (CVE-2005-4667) As well, this update adds support for files larger than 2GB. All users of unzip should upgrade to these updated packages, which contain backportedpatches that resolve these issues. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. Use Red Hat Network to download and update your packages. To launch the Red Hat Update Agent, use the following command: up2date For information on how to install packages manually, refer to the following Web page for the System Administration or Customization guide specific to your system: https://docs.redhat.com/en/documentation/red_hat_enterprise_linux/10 5.

This update fixes several vulnerabilities in the unzip utility.. ---------------------------------------------------------------------Fedora Update Notification FEDORA-2006-098 2006-02-06 ---------------------------------------------------------------------Product : Fedora Core 4 Name : unzip Version : 5.51 Release : 13.fc4 Summary : A utility for unpacking zip files. Description : The unzip utility is used to list, test, or extract files from a zip archive. Zip archives are commonly found on MS-DOS systems. The zip utility, included in the zip package, creates zip archives. Zip and unzip are both compatible with archives created by PKWARE(R)'s PKZIP for MS-DOS, but the programs' options and default behaviors do differ in some respects. Install the unzip package if you need to list, test or extract files from a zip archive. ---------------------------------------------------------------------* Mon Feb 6 2006 Ivana Varekova 5.51-13.fc4 - fix bug 178961 - CVE-2005-4667 - unzip long file name buffer overflow * Wed Aug 3 2005 Ivana Varekova 5.51-12.fc4 - fix bug 164928 - TOCTOU issue in unzip * Mon May 9 2005 Ivana Varekova 5.51-11 - fix bug 156959 – invalid file mode on created files ---------------------------------------------------------------------This update can be downloaded from: 0b621ba9565ce4507c6809e342dfdfea2cceec46 SRPMS/unzip-5.51-13.fc4.src.rpm e8f67af74893566142d7c4a957fd1f6ca6aca209 ppc/unzip-5.51-13.fc4.ppc.rpm 268b5b2e62fdd4263b4849cac5d3ae915f5095d7 ppc/debug/unzip-debuginfo-5.51-13.fc4.ppc.rpm 5fe96c87893982f2752d0f528e1691591d8b655e x86_64/unzip-5.51-13.fc4.x86_64.rpm 47676a08bd382d976c08ea3927b51fd07cb67850 x86_64/debug/unzip-debuginfo-5.51-13.fc4.x86_64.rpm 69cf5c0e4faf82e7e5305abe5cf7feb8d480ba99 i386/unzip-5.51-13.fc4.i386.rpm c7260e51f7b60ffbf92a99c44caa928e5cb50df6 i386/debug/unzip-debuginfo-5.51-13.fc4.i386.rpm This update can be installed with the 'yum' updateprogram.
