Bug#926136: stretch-pu: package zziplib/0.13.62-3.2~deb9u1
Package: release.debian.org
Severity: normal
Tags: stretch
User: release.debian.org@packages.debian.org
Usertags: pu
Hi Stable release managers,
Several CVEs were adressed with the 0.13.62-3.2 to unstable (and
buster) which are CVE-2018-6381, CVE-2018-6484, CVE-2018-6541,
CVE-2018-6869, CVE-2018-6540, CVE-2018-7725, CVE-2018-7726 and
CVE-2018-16548.
Given 0.13.62-3.1 beeing in stable and 0.13.62-3.2 consisted only on
those CVE fixes, I would like to propose a rebuild of 0.13.62-3.2 to
be included in stretch in the upcoming point release and adress those
CVEs.

Attaching the debdiff against 0.13.62-3.1.
AFAICS no regression were reported for 0.13.62-3.2.
