Summary

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 this issue.
Users of cpio are advised to upgrade to this updated package, which contains a backported patch to correct this issue.
