To help reduce impacts and increase resilience, NOAA Fisheries is assessing the vulnerability of fish species, protected species (marine mammals, sea turtles), habitats and fishing communities to changing climate and ocean conditions. See below for information on the existing vulnerability assessments.

To respond to and prepare for changes in climate and oceans, decision-makers need information about what species may be most vulnerable and why. Climate Vulnerability Assessments identify what species, habitats or communities may be most vulnerable based on their exposure to projected changes in the environment (e.g., warming oceans) and their sensitivity or adaptability to handle those changes based on their life history characteristics (e.g., reproductive rates, diet etc). Vulnerability assessments can help identify areas where additional research and action is needed to reduce risks. Information on the methods NOAA Fisheries uses to assess climate vulnerability is available below.

This chart describes the basic steps of a fish species climate vulnerability assessment. Information on the methodology for assessing vulnerability of fish and invertebrates is here. Information on the methodology for assessing vulnerability of marine mammals is here.

NOAA Fisheries has created the Climate Vulnerability Assessment Tool, which includes most of the current vulnerability assessments. Users can navigate the available data sets and access information regarding the vulnerability of various species and habitats.

In New York City, the risk of death from heat is unfairly distributed across neighborhoods. We identified neighborhood environmental and social factors associated with increased risk to create a heat vulnerability index. This can identify neighborhoods at highest risk and help inform neighborhood-level policies and programs that can protect people - sending resources to where they're needed the most.

Daytime summer surface temperature is different from air temperature, and varies more by neighborhood: some neighborhoods are hotter than others. A higher surface temperature is associated with a higher risk of death from heat waves. Median neighborhood: 87.0 F

Green space is tree, grass, or shrub cover. Green space helps cool a neighborhood, address the UHI, and create a resilient city. It also has a small association with heat mortality, weaker than other components in the index. Median neighborhood: 25.0%

Air conditioning is as necessary during extreme heat as heating is in winter. A neighborhood with a high percentage of households with air conditioners means that more of its residents can be protected from extreme heat. Citywide: 91.0%

Low income is a social factor that places people at risk of death during heat waves for many reasons. One reason is that people with limited financial resources may be less likely to afford owning or using an air conditioner during heat waves. Citywide: $67,046

Black New Yorkers suffer these disproportionate health impacts from heat due to social and economic disparities. These disparities stem from structural racism, which includes neighborhood disinvestment, racist housing policies, fewer job opportunities and lower pay, and less access to high-quality education and health care.

You can learn more about what the City is doing to address extreme heat and how the HVI is guiding that work in the 2023 PlaNYC: Getting Sustainability Done report and at Cool Neighborhoods NYC. Communities can also use the index to advocate for services and resources.

Based on searches using Censys and Shodan, we have identified over 14 million potentially vulnerable OpenSSH server instances exposed to the Internet. Anonymized data from Qualys CSAM 3.0 with External Attack Surface Management data reveals that approximately 700,000 external internet-facing instances are vulnerable. This accounts for 31% of all internet-facing instances with OpenSSH in our global customer base. Interestingly, over 0.14% of vulnerable internet-facing instances with OpenSSH service have an End-Of-Life/End-Of-Support version of OpenSSH running.

In our security analysis, we identified that this vulnerability is a regression of the previously patched vulnerability CVE-2006-5051, which was reported in 2006. A regression in this context means that a flaw, once fixed, has reappeared in a subsequent software release, typically due to changes or updates that inadvertently reintroduce the issue. This incident highlights the crucial role of thorough regression testing to prevent the reintroduction of known vulnerabilities into the environment. This regression was introduced in October 2020 (OpenSSH 8.5p1).

Qualys has developed a working exploit for the regreSSHion vulnerability. As part of the disclosure process, we successfully demonstrated the exploit to the OpenSSH team to assist with their understanding and remediation efforts. We do not release our exploits, as we must allow time for patches to be applied. However, even though the exploit is complex, we believe that other independent researchers will be able to replicate our results.

OpenSSH (Open Secure Shell) is a suite of secure networking utilities based on the Secure Shell (SSH) protocol, which is vital for secure communication over unsecured networks. It provides robust encryption to ensure privacy and secure file transfers, making it an essential tool for remote server management and secure data communication. Known for its extensive security and authentication features, OpenSSH supports various encryption technologies and is standard on multiple Unix-like systems, including macOS and Linux.

OpenSSH stands as a benchmark in software security, exemplifying a robust defense-in-depth approach. Despite the recent vulnerability, its overall track record remains exceptionally strong, serving as both a model and an inspiration in the field.

This vulnerability, if exploited, could lead to full system compromise where an attacker can execute arbitrary code with the highest privileges, resulting in a complete system takeover, installation of malware, data manipulation, and the creation of backdoors for persistent access. It could facilitate network propagation, allowing attackers to use a compromised system as a foothold to traverse and exploit other vulnerable systems within the organization.

Moreover, gaining root access would enable attackers to bypass critical security mechanisms such as firewalls, intrusion detection systems, and logging mechanisms, further obscuring their activities. This could also result in significant data breaches and leakage, giving attackers access to all data stored on the system, including sensitive or proprietary information that could be stolen or publicly disclosed.

This vulnerability is challenging to exploit due to its remote race condition nature, requiring multiple attempts for a successful attack. This can cause memory corruption and necessitate overcoming Address Space Layout Randomization (ASLR). Advancements in deep learning may significantly increase the exploitation rate, potentially providing attackers with a substantial advantage in leveraging such security flaws.

Addressing the regreSSHion vulnerability in OpenSSH, which enables remote code execution on Linux systems, demands a focused and layered security approach. Here are concise steps and strategic recommendations for enterprises to safeguard against this significant threat:

Qualys is cutting the release cycle short for certain products that are deployed on customer premises. At least one of those products depends on a supplier that will publish a fix release shortly. We intend to release fixes for this Severity HIGH CVE in the coming days to ensure that customers are safe from regreSSHion. Once builds have cleared Quality Assurance, we will provide updates to help customers patch.

No, as part of our commitment to responsible disclosure and maintaining high-security standards, we will not publish exploit codes. Given the complexity of this vulnerability, it is crucial to allow organizations to apply patches effectively without the immediate pressure of public exploits.

This fix is part of a major update, making it challenging to backport. Consequently, users will have two update options: upgrading to the latest version released on Monday, July 1st (9.8p1) or applying a fix to older versions as outlined in the advisory, which is the approach most vendors will take.

Users can determine if their systems are vulnerable by verifying the version of the OpenSSH server installed. Systems running affected versions should be considered at risk and prioritized for updates.
