|Gentoo Linux Security Advisory
Title: cpio: Arbitrary code execution (GLSA 201311-21)
Date: November 28, 2013
A heap-based buffer overflow in cpio might allow a remote rmt
server to execute arbitrary code or cause a Denial of Service condition.
GNU cpio copies files into or out of a cpio or tar archive.
Vulnerable: < 2.11
Unaffected: >= 2.11
Architectures: All supported architectures
Cpio contains a heap-based buffer overflow in the rmt_read__ function in
A remote server could sending more data than was requested, related to
archive filenames that contain a : (colon) character, possibly resulting
in execution of arbitrary code or a Denial of Service condition.
There is no known workaround at this time.
All cpio users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=app-arch/cpio-2.11"
