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-5039-1 advisory.

 - A heap out-of-bounds write affecting Linux since v2.6.19-rc1 was discovered in net/netfilter/x_tables.c.
 This allows an attacker to gain privileges or cause a DoS (via heap memory corruption) through user name space (CVE-2021-22555)
