CVE-2024-45780

A flaw was found in grub2. When reading tar files, grub2 allocates an internal buffer for the file name. However, it fails to properly verify the allocation against possible integer overflows. It's possible to cause the allocation length to overflow with a crafted tar file, leading to a heap...

UBUNTU-CVE-2024-45777

A flaw was found in grub2. The calculation of the translation buffer when reading a language .mo file in grubgettextgetstrfromposition may overflow, leading to a Out-of-bound write. This issue can be leveraged by an attacker to overwrite grub2's sensitive heap data, eventually leading to the...

UBUNTU-CVE-2025-0622

A flaw was found in command/gpg. In some scenarios, hooks created by loaded modules are not removed when the related module is unloaded. This flaw allows an attacker to force grub2 to call the hooks once the module that registered it was unloaded, leading to a use-after-free vulnerability. If...

UBUNTU-CVE-2024-45781

A flaw was found in grub2. When reading a symbolic link's name from a UFS filesystem, grub2 fails to validate the string length taken as an input. The lack of validation may lead to a heap out-of-bounds write, causing data integrity issues and eventually allowing an attacker to circumvent secure...

UBUNTU-CVE-2025-0678

A flaw was found in grub2. When reading data from a squash4 filesystem, grub's squash4 fs module uses user-controlled parameters from the filesystem geometry to determine the internal buffer size, however, it improperly checks for integer overflows. A maliciously crafted filesystem may lead some ...

UBUNTU-CVE-2025-0685

A flaw was found in grub2. When reading data from a jfs filesystem, grub's jfs filesystem module uses user-controlled parameters from the filesystem geometry to determine the internal buffer size, however, it improperly checks for integer overflows. A maliciouly crafted filesystem may lead some o...

UBUNTU-CVE-2025-0686

A flaw was found in grub2. When performing a symlink lookup from a romfs filesystem, grub's romfs filesystem module uses user-controlled parameters from the filesystem geometry to determine the internal buffer size, however, it improperly checks for integer overflows. A maliciously crafted...

UBUNTU-CVE-2025-0684

A flaw was found in grub2. When performing a symlink lookup from a reiserfs filesystem, grub's reiserfs fs module uses user-controlled parameters from the filesystem geometry to determine the internal buffer size, however, it improperly checks for integer overflows. A maliciouly crafted filesyste...

GNU GRUB 输入验证错误漏洞

GRUB2 is a multiple bootloader for the GNU Project. GNU GRUB2 suffers from a buffer overflow vulnerability that stems from a buffer overflow problem contained in reading the BFS file system. An attacker could exploit this vulnerability to cause a denial of service...

CVE-2024-57258

CVE-2024-57258 affects Das U-Boot (pre-2025.01-rc1) with integer overflows in memory allocation. Exploitation can occur via a crafted squashfs filesystem (via sbrk or request2size) or due to mishandling ptrdiff_t on x86_64, leading to memory corruption. Connected advisories corroborate the issue ...
