Hello release team,

yet another security issue was found in file/libmagic: "The do_core_note
function in readelf.c in libmagic.a in file 5.33 allows remote attackers
to cause a denial of service (out-of-bounds read and application crash)
via a crafted ELF file" (CVE-2018-10360)

https://security-tracker.debian.org/tracker/CVE-2018-10360
https://bugs.debian.org/901351

After a brief discussion with the security team we agreed this should be
addressed in the upcoming point release, so here we go.

Following the new policy, I've already uploaded file_5.22+15-2+deb8u4 to
oldstable.

Kind regards,

    Christoph Biedl
