Astra Linux - уязвимость в grub2
A flaw was discovered in grub2. When performing a symlink lookup from a ReiserFS filesystem, grub’s ReiserFS module uses user-controlled parameters from the filesystem’s geometry to determine the internal buffer size. However, it improperly checks for integer overflows. A maliciously crafted...
Astra Linux - уязвимость в grub2
A out-of-bounds read flaw was discovered in Grub2’s NTFS filesystem driver. This issue may allow a physically present attacker to present a specially crafted NTFS file system image to read arbitrary memory locations. A successful attack can result in sensitive data cached in memory or EFI variabl...
Astra Linux - уязвимость в grub2
A use-after-free vulnerability has been identified in the GNU GRUB Grand Unified Bootloader. The flaw occurs because the process that closes files improperly retains a memory pointer, leaving an invalid reference to a file system structure. An attacker could exploit this vulnerability to cause th...
