Read Time:20 Second

Several vulnerabilities were discovered in OpenAFS, an implementation of
the AFS distributed filesystem, which may result in theft of credentials
in Unix client PAGs (CVE-2024-10394), fileserver crashes and information
leak on StoreACL/FetchACL (CVE-2024-10396) or buffer overflows in XDR
responses resulting in denial of service and potentially code execution
(CVE-2024-10397).

Friday Squid Blogging: Cotton-and-Squid-Bone Sponge

Read Time:43 Second

News:

A sponge made of cotton and squid bone that has absorbed about 99.9% of microplastics in water samples in China could provide an elusive answer to ubiquitous microplastic pollution in water across the globe, a new report suggests.

[…]

The study tested the material in an irrigation ditch, a lake, seawater and a pond, where it removed up to 99.9% of plastic. It addressed 95%-98% of plastic after five cycles, which the authors say is remarkable reusability.

The sponge is made from chitin extracted from squid bone and cotton cellulose, materials that are often used to address pollution. Cost, secondary pollution and technological complexities have stymied many other filtration systems, but large-scale production of the new material is possible because it is cheap, and raw materials are easy to obtain, the authors say.
