Hello release team,
[ same as for jessie in #-1, so just for completeness ]
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_5.30-1+deb9u2 to
stable.
Kind regards,
Christoph Biedl
