It looks like you may be using a web browser version that we don't support. Make sure you're using the most recent version of your browser, or try using of these supported browsers, to get the full Made experience: Chrome, Firefox, Safari, or Edge.
Among the largest species to call Mystic Aquarium home, the Steller sea lions are also the largest of the Otariidae family (the group that includes sea lions and fur seals). Males can reach sizes of 11 feet in length and 2,400 pounds, while females are smaller at nine-and-a-half feet in length and 700 pounds.
Having been separated from his mother as a pup, Astro was rescued off the coast of California in 2006 and received outstanding care from the Marine Mammal Center for nearly a year. Following three attempts to return him to his natural environment, the Center realized Astro was not able to reintegrate into the wild sea lion population. Needing a permanent home, Astro arrived at Mystic Aquarium in 2008.
Steller sea lions are protected under both the Endangered Species Act and the Marine Mammal Protection Act. The western distinct population segment is listed as endangered under the ESA. They are classified by the IUCN Red list as Near-Threatened.
Firefox 9 has just been released for Mac OS X, Windows, and Linux. The latest version brings some significant boosts to javascript performance, some theme fixes, and a variety of other under-the-hood enhancements. Probably the most noticeable addition will be for OS X Lion users though, with the addition of two-fingered swipe gesture navigation.
years behind from Safari. there is no pinch Zoom or two finger tap zoom.
although pinch zoom can be activated by some tweaks but not smooth. safari-5 star, Chrome-4star, Opera-3 star, firefox-2star
Rezilion analysis reveals that there are several common Linux applications that contain or use the vulnerable libwebp package as a dependency. Examples include: libtiff, python-pillow, libgd, gnuplot, libavcodec58, libmagickcor, libqt5webkit5, libgvc6, libimlib2, and others.
Rezilion has also identified the vulnerable library in several popular container images latest versions, collectively downloaded and deployed billions of times, such as Nginx,Python, Joomla, WordPress, Node.js, and more.
While identified exploitation attempts were initially associated with various web-browsers, it is important to make sure to update any affected instances of the libwebp package as the possibility exists that additional exploitation scenarios are possible.
Up until now, the relationship between these two cases was still unknown, but these similarities got us thinking that there is a stronger connection between these vulnerabilities. Apparently, we were not the only ones having these thoughts. .
These thoughts triggered an in-depth analysis that uncovered the true scope of this vulnerability, revealed inherent detection gaps for most traditional vulnerability scanners, as well as raised some questions regarding the CVE assignment process.
We have analyzed the ImageIO binaries on a MacOS system and were able to find evidence that libwebp is indeed used. Moreover, we identified both vp8l_dec.c, and huffman_utils.c, the vulnerable files for CVE-2023-4863, being referenced as part of ImageIO.
Well, it seems that the researchers have reported the issue to the Google and Apple teams where each team issued a separate CVE. Google scoped the vulnerability as affecting Chrome while Apple associated it with their internal ImageIO framework and hence scoped the issue as affecting only AppleOSs.
Since the vulnerability is scoped under the overarching product containing the vulnerable dependency, the vulnerability will only be flagged by vulnerability scanners for these specific products. This creates a HUGE blindspot for organizations blindly relying on the output of their vulnerability scanner.
Due to this reason, for nearly a week after the vulnerability was added to the CISA KEV catalog, the majority of packages that depend on libwebp were not identified as affected by CVE-2023-4863 by any vulnerability scanners.
Just recently NVD updated the entry for CVE-2023-4863 to reflect that the vulnerability affects libwebp. Scanners that keep track of these changes in NVD metadata should now be able to start identifying CVE-2023-4863 more reliably.
The issue was fixed in the following commit in the BuildHuffmanTable, it adds a check if the data is valid and allocates more memory if not enough in order to prevent attackers from overwriting the table with invalid data.
While the vulnerability initially seems to target Chromium-based applications, now that we know better, we understand that it possesses the potential to affect a much wider range of software and applications relying on the ubiquitous libwebp package for WebP codec functionality. This package stands out for its efficiency, outperforming JPEG and PNG in terms of size and speed. Consequently, a multitude of software, applications, and packages have adopted this library, or even adopted packages that libwebp is their dependency, creating a complex challenge when attempting to identify vulnerable systems. The sheer prevalence of libwebp extends the attack surface significantly, raising serious concerns for both users and organizations.
Organizations with SBOM solutions in their environment are advised to query the Software Bill of Materials (SBOM) for any package using a vulnerable version of libwebp as a dependency. It is especially important to make sure that the system libwebp library is patched as several applications such as chromium for example, are built against the system libwebp library.
Given the confirmed exploitation of CVE-2023-4863 in the wild, it is imperative to swiftly apply the provided patches to your systems. These patches have been specifically designed to address this critical vulnerability and should be deployed without delay.
Given the initial wrong scoping of the vulnerability, scanners output for CVE-2023-4863 should be taken with a grain of salt, and it is advised to either query your SBOM solution or asset inventory system for specific occurrences of libwebp in all of its vulnerable variations.
For software, applications, or packages that dynamically incorporate the libwebp package into their code rather than statically linking it, updating the libwebp library to the latest version is crucial. After the update, it is advisable to restart these applications to ensure the changes take effect.
Although this blog post primarily addresses CVE-2023-4863, we would also like to emphasize the importance of addressing CVE-2023-41064 and CVE-2023-41061 since they were published recently, are zero-day vulnerabilities, and are known to be exploited in the wild. It seems these CVEs are simply a manifestation of the same issue affecting separate OSs. Hence, it is advisable to take swift action and apply patches to macOS Ventura 13.5.2 and watchOS 9.6.2, where applicable.
Because CVE-2023-4863 was wrongly scoped as a browser vulnerability, most scanners will fail to detect it in cases where the libwebp library is being used as a dependency. Organizations should consider adopting alternative tooling to ensure all instances are detected and can be addressed promptly.
For example, in this screenshot from the Rezilion platform, on the right hand side you can see examples of various components that are dependent on vulnerable versions of libwebp, including whether these components are actually in use (loaded to memory) or not :
A coalition of Internet companies, including U.S.-based Google, has agreed to support a "do-not-track" button being installed in Web browsers to help protect the privacy of computer users around the world.
For more than a year, the Internet browser companies had resisted embedding the button. But slowly, various browsing companies have adopted the "do-not-track" feature, including Mozilla with its Firefox browser, Microsoft with Internet Explorer and Apple with its Mountain Lion operating system.
On Thursday, Google, the world's most popular search engine, said it, too, would join a broad coalition of 400 technology, advertising and media companies to support the anti-tracking effort. Google's announcement came hours before President Barack Obama called on Congress to pass legislation defining a "privacy bill of rights" for Internet users.
Obama said the privacy standards are necessary because he said "consumer trust is essential for the continued growth of the digital economy."
The U.S.-based Internet industry, fueled annually by nearly $40 billion in online advertising, has been caught in several privacy disputes as advanced technology has been created that can track users' viewing habits. Most disputes have involved claims that the browser companies have deceptively collected information about which Internet sites people have visited and then used it to customize advertising sent to users or for other commercial purposes.
Under the new agreement, the Internet companies have pledged within the next nine months to begin stopping customizing advertising or to use the data for employment, credit, health care or insurance purposes. They still would be able to use tracking information for broader "market research" or "product development" purposes.
Feline immunodeficiency virus (FIV) naturally infects multiple species of cat and is related to human immunodeficiency virus in humans. FIV infection causes AIDS-like disease and mortality in the domestic cat (Felis catus) and serves as a natural model for HIV infection in humans. In African lions (Panthera leo) and other exotic felid species, disease etiology introduced by FIV infection are less clear, but recent studies indicate that FIV causes moderate to severe CD4 depletion.
In this study, comparative genomic methods are used to evaluate the full proviral genome of two geographically distinct FIV subtypes isolated from free-ranging lions. Genome organization of FIVPle subtype B (9891 bp) from lions in the Serengeti National Park in Tanzania and FIVPle subtype E (9899 bp) isolated from lions in the Okavango Delta in Botswana, both resemble FIV genome sequence from puma, Pallas cat and domestic cat across 5' LTR, gag, pol, vif, orfA, env, rev and 3'LTR regions. Comparative analyses of available full-length FIV consisting of subtypes A, B and C from FIVFca , Pallas cat FIVOma and two puma FIVPco subtypes A and B recapitulate the species-specific monophyly of FIV marked by high levels of genetic diversity both within and between species. Across all FIVPle gene regions except env, lion subtypes B and E are monophyletic, and marginally more similar to Pallas cat FIVOma than to other FIV. Sequence analyses indicate the SU and TM regions of env vary substantially between subtypes, with FIV Ple subtype E more related to domestic cat FIVFca than to FIVPle subtype B and FIVOma likely reflecting recombination between strains in the wild.
