Astra Linux – Vulnerability in imagemagick

A vulnerability was discovered in ImageMagick, causing a value of type ‘unsigned char’ to fall outside the representable value range when crafted or untrusted input is processed in the coders/psd.c file. This results in a negative impact on the availability of the application or other problems...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: mmmremap.c: Avoid unnecessary calls to invalidrangestart/invalidaterangeend when using mremap with oldsize=0. If the mremap system call with oldsize=0 ends up in movepagetables, it will unnecessarily call...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: ksmbd: The lock-range check for files with equal size is skipped, to avoid underflow when size == 0. When size equals the current isize including 0, the code that calls checklockrangefilp, isize, size - 1, WRITE will compute size...

In the Linux kernel, the following vulnerabilities have been resolved: arm64: mm: fixed the sanity check for VA-range Both createmappingnoalloc and updatemappingprot perform sanity checks on their ‘virt’ parameter. However, the check itself doesn’t make much sense. The condition used today seems ...

Astra Linux – Vulnerability in libsoup2.4

A flaw was discovered in libsoup. The implementation of HTTP range requests is vulnerable to a resource consumption attack. This flaw allows a malicious client to request the same range multiple times in a single HTTP request, causing the server to use large amounts of memory. This does not resul...
