Ubuntu 18.04 LTS / 20.04 LTS : MongoDB vulnerability (USN-8160-1)

high Nessus Plugin ID 306093

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-8160-1 advisory.

 It was discovered that MongoDB incorrectly handled length parameters in zlib-compressed network messages prior to authentication. An unauthenticated remote attacker could possibly use this issue to cause MongoDB to allocate an oversized memory buffer, resulting in the exposure of sensitive information.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

Solution

Update the affected packages.
