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. 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.
