CVE-2024-45778
CVE-2024-45778 affects grub2, caused by a stack overflow when reading a BFS filesystem. A crafted BFS image can trigger an uncontrolled loop and crash grub2, per the NVD entry. Likely impact is availability (HIGH), with local access required (attack vector LOCAL), low attack complexity and low pr...
CVE-2024-45778 Grub2: fs/bfs: integer overflow in the bfs parser.
A stack overflow flaw was found when reading a BFS file system. A crafted BFS filesystem may lead to an uncontrolled loop, causing grub2 to crash...
AZL-57513 CVE-2025-1125 affecting package grub2 for versions less than 2.06-25
When reading data from a hfs filesystem, grub's hfs filesystem module uses user-controlled parameters from the filesystem metadata to calculate the internal buffers size, however it misses to properly check for integer overflows. A maliciouly crafted filesystem may lead some of those buffer size...
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...
AZL-57498 CVE-2024-45779 affecting package grub2 for versions less than 2.06-25
An integer overflow flaw was found in the BFS file system driver in grub2. When reading a file with an indirect extent map, grub2 fails to validate the number of extent entries to be read. A crafted or corrupted BFS filesystem may cause an integer overflow during the file reading, leading to a he...
