How to fix?

Upgrade Debian:13 cpio to version 2.13+dfsg-5 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream cpio package and not the cpio package as distributed by Debian. See How to fix? for Debian:13 relevant fixed versions and status.

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.
