An updated cpio package that fixes a security issue and various bugs is now available.

This update has been rated as having low security impact by the Red Hat Security Response Team.

GNU cpio copies files into or out of a cpio or tar archive.

A buffer overflow was found in cpio on 64-bit platforms. By tricking a user into adding a specially crafted large file to a cpio archive, a local attacker may be able to exploit this flaw to execute arbitrary code with the target user's privileges. (CVE-2005-4268)

This erratum also addresses the following bugs :

* cpio did not set exit codes appropriately.

* cpio did not create a ram disk properly.

All users of cpio are advised to upgrade to this updated package, which contains backported fixes to correct these issues.

An updated cpio package that fixes two security issues is now available for Red Hat Enterprise Linux 3.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

GNU cpio copies files into or out of a cpio or tar archive.

A heap-based buffer overflow flaw was found in the way cpio expanded archive files. If a user were tricked into expanding a specially crafted archive, it could cause the cpio executable to crash or execute arbitrary code with the privileges of the user running cpio.
(CVE-2010-0624)

Red Hat would like to thank Jakob Lell for responsibly reporting the CVE-2010-0624 issue.

A stack-based buffer overflow flaw was found in the way cpio expanded large archive files. If a user expanded a specially crafted archive, it could cause the cpio executable to crash. This issue only affected 64-bit platforms. (CVE-2005-4268)

Users of cpio are advised to upgrade to this updated package, which contains backported patches to correct these issues.

CVE-2010-0624 tar, cpio: Heap-based buffer overflow by expanding a specially crafted archive

A heap-based buffer overflow flaw was found in the way cpio expanded archive files. If a user were tricked into expanding a specially crafted archive, it could cause the cpio executable to crash or execute arbitrary code with the privileges of the user running cpio.
(CVE-2010-0624)

A stack-based buffer overflow flaw was found in the way cpio expanded large archive files. If a user expanded a specially crafted archive, it could cause the cpio executable to crash. This issue only affected 64-bit platforms. (CVE-2005-4268) - SL3 Only

The remote VMware ESX host is missing a security-related patch. It is, therefore, affected by multiple vulnerabilities, including remote code execution vulnerabilities, in several third-party components and libraries :

  - GNU cpio
  - GNU cpio on 64-bit
  - GNU tar
  - Kerberos 5
  - Perl
  - PostgreSQL
  - Safe Module for Perl Automagic Methods
  - Samba smbd

Richard Harms discovered that cpio did not sufficiently validate file properties when creating archives. Files with e. g. a very large size caused a buffer overflow. By tricking a user or an automatic backup system into putting a specially crafted file into a cpio archive, a local attacker could probably exploit this to execute arbitrary code with the privileges of the target user (which is likely root in an automatic backup system).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

A buffer overflow in cpio 2.6 on 64-bit platforms could allow a local user to create a DoS (crash) and possibly execute arbitrary code when creating a cpio archive with a file whose size is represented by more than 8 digits.

The updated packages have been patched to correct these problems.
