CVE-2021-38185: GNU cpio through 2.13 allows attackers to execute arbitrary code via a crafted pattern file, because of a dstring.c ds_fgetstr integer overflow that triggers an out-of-bounds heap write. NOTE: it is unclear whether there are common cases where the pattern file, associated with the -E option, is untrusted data. Fix is https://git.savannah.gnu.org/cgit/cpio.git/commit/?id=dd96882877721703e19272fe25034560b794061b according to https://lists.gnu.org/archive/html/bug-cpio/2021-08/msg00002.html
Ping. No release yet, is the patch suitable?
