cpio: Arbitrary code execution A heap-based buffer overflow in cpio might allow a remote rmt server to execute arbitrary code or cause a Denial of Service condition. cpio 2013-11-28 2013-11-28 314663 remote 2.11 2.11

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

Cpio contains a heap-based buffer overflow in the rmt_read__ function in lib/rtapelib.c.

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:
