Synopsis

The remote Debian host is missing a security-related update.

Description

The remote Debian 9 host has packages installed that are affected by a vulnerability as referenced in the dla-2898 advisory.

It was found that nss, the Mozilla Network Security Service library, was vulnerable to a NULL pointer dereference when parsing empty PKCS 7 sequences, which could result in denial of service. For Debian 9 stretch, this problem has been fixed in version 2:3.26.2-1.1+deb9u5. We recommend that you upgrade your nss packages. For the detailed security status of nss please refer to its security tracker page at:
