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


The remote Debian 10 / 11 host has packages installed that are affected by a vulnerability as referenced in the dsa-5111 advisory.

- zlib before 1.2.12 allows memory corruption when deflating (i.e., when compressing) if the input has many distant matches. (CVE-2018-25032)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
