critical Nessus Plugin ID 183634

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 ESM / 18.04 ESM host has packages installed that are affected by a vulnerability as referenced in the USN-4828-1 advisory.

 It was discovered that librelp did not properly manage x509 certificates, leading to a stack-based buffer overflow. A remote attacker could possibly use this issue to execute arbitrary code.

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 librelp-dev and / or librelp0 packages.
