Ubuntu 16.04 ESM : GCC vulnerability (USN-5770-1)

medium Nessus Plugin ID 168518

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 ESM host has packages installed that are affected by a vulnerability as referenced in the USN-5770-1 advisory.

Todd Eisenberger discovered that certain versions of GNU Compiler Collection (GCC) could be made to clobber the status flag of RDRAND and RDSEED with specially crafted input. This could potentially lead to less randomness in random number generation.

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.
