In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: A fix was made to prevent division by zero in the setupdscconfig function. When sliceheight is 0, dividing by sliceheight in the calculation of the number of slices can lead to a division by zero, causing the...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

Transmitted requests in Xen’s virtual network protocol can consist of multiple parts. Although none of them are actually useful, except for the initial part, any of these parts can be of zero length, meaning they carry no data at all. Apart from the certain initial portion of the data to be...

Astra Linux – Vulnerability in Waitress

Waitress is a Web Server Gateway Interface server for Python 2 and 3. When a remote client closes the connection before Waitress has had the opportunity to call getpeername, Waitress will not properly clean up the connection. As a result, the main thread attempts to write to a socket that no long...

Astra Linux – Vulnerability in imagemagick

ImageMagick is free and open-source software used for editing and manipulating digital images. In versions below 7.1.2-189 and 6.9.13-44, when “Magick” parses an XML file, it is possible that a single zero-byte may be written out of the bounds. This issue has been fixed in versions 6.9.13-44 and...
