Astra Linux – Vulnerability in imagemagick

A flaw was discovered in ImageMagick, specifically in the code file coders/bmp.c. An attacker who submits a crafted file processed by ImageMagick could trigger undefined behavior, resulting in values that are outside the range of the type unsigned int. This likely leads to a disruption in the...

Astra Linux – Vulnerability in grub2

A flaw was discovered in grub2 in versions prior to 2.06, where it incorrectly enabled the use of the ACPI command when Secure Boot was enabled. This flaw allows an attacker with privileged access to create a Secondary System Description Table SSDT containing code that can overwrite the Linux...
