Astra Linux – Vulnerability in grub2

The GRUB2’s shimlock verifier allows non-kernel files to be loaded on shim-powered secure boot systems. Allowing such files to be loaded may lead to unverified code and modules being loaded in GRUB2, thereby breaking the secure boot trust-chain...

Astra Linux – Vulnerability in grub2

A flaw was discovered in grub2 in versions prior to 2.06. The rmmod implementation allows the unloading of a module that serves as a dependency without checking whether any other dependent modules are still loaded, resulting in a “use-after-free” scenario. This could allow arbitrary code to be...

Astra Linux – Vulnerability in grub2

A crafted 16-bit grayscale PNG image may lead to an out-of-bounds write in the heap area. An attacker may exploit this to cause heap data corruption or, ultimately, arbitrary code execution and circumvent secure boot protections. This issue is highly complex to exploit; an attacker needs to perfo...

Astra Linux – Vulnerability in grub2

A flaw was discovered in grub2 in versions prior to 2.06. The cutmem command does not honor secure boot locking, allowing a privileged attacker to remove address ranges from memory. This creates an opportunity to circumvent SecureBoot protections after proper analysis of grub’s memory layout. The...

Astra Linux – Vulnerability in grub2

A buffer overflow was detected in grubfontconstructglyph. A maliciously crafted pf2 font can cause an overflow when calculating the maxglyphsize value. This results in allocating a buffer that is smaller than necessary for the glyph, leading to another buffer overflow and an out-of-bounds write t...

Astra Linux – Vulnerability in grub2

A flaw was discovered in grub2 in versions prior to 2.06. The Setparamprefix function in the menu rendering code performs a length calculation based on the assumption that expressing a single quoted character would require 3 characters. However, in reality, it requires 4 characters. This allows a...

Astra Linux – Vulnerability in grub2

A heap out-of-bounds write may occur during the handling of Huffman tables in the PNG reader. This may lead to data corruption in the heap space. The impacts on confidentiality, integrity, and availability are considered low, as it is very complex for an attacker to control the encoding and...
