Synopsis

The remote Debian host is missing a security update.

Description

An issue has been found in bacula, a network backup service. By sending oversized digest strings a malicious client can cause a heap overflow in the director's memory which results in a denial of service.

For Debian 9 stretch, this problem has been fixed in version 7.4.4+dfsg-6+deb9u2.

We recommend that you upgrade your bacula packages.

For the detailed security status of bacula please refer to its security tracker page at:

Solution

Upgrade the affected packages.
