A Vulnerability in C Standard Libraries uClibe and uClibe-ng Could Allow for DNS Poisoning

Read Time:36 Second

A vulnerability which could allow for DNS poisoning attacks has been discovered in the C standard libraries uClibe and uClibe-ng, which are widely used in IoT products. DNS poisoning enables a subsequent Man-in-the-Middle scenario, which can be used to perform actions like stealing information, forcing authenticated responses, as well as installing malicious firmware.
There is currently no CVE listing, nor further details on affected products, as the research group Nozomi Networks is still working with vendors and library developers in finding a solution.
The MS-ISAC believes that due to various mitigating factors, this vulnerability does not pose an immediate threat to our member base. We would, however, like to share relevant details for your situational awareness.

Multiple vulnerabilities have been discovered in Mozilla Firefox and Firefox Extended Support Release (ESR), the most severe of which could allow for arbitrary code execution.

Mozilla Firefox is a web browser used to access the Internet.
Mozilla Firefox ESR is a version of the web browser intended to be deployed in large organizations.
Successful exploitation of the most severe of these vulnerabilities could allow for arbitrary code execution. Depending on the privileges associated with the user an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.
