Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-4598-1 advisory.

- LibEtPan through 1.9.4, as used in MailCore 2 through 0.6.3 and other products, has a STARTTLS buffering issue that affects IMAP, SMTP, and POP3. When a server sends a begin TLS response, the client reads additional data (e.g., from a meddler-in-the-middle attacker) and evaluates it in a TLS context, aka response injection. (CVE-2020-15953)

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

Update the affected libetpan-dev and / or libetpan17 packages.
