CVE-2024-57262
HighSummary
W barebox przed wersją 2025.01.0 występuje przepełnienie całkowitej liczby w funkcji ext4fs_read_symlink, które może być wywołane przez spreparowany system plików ext4 z rozmiarem inode równym 0xffffffff. To prowadzi do alokacji pamięci o rozmiarze zero i nadpisania pamięci.
Risk Assessment
Podatność ta może prowadzić do poważnych problemów z bezpieczeństwem, w tym do nadpisania pamięci, co może umożliwić atakującym wykonanie złośliwego kodu lub destabilizację systemu.
Recommendation
Zaleca się aktualizację do wersji barebox 2025.01.0 lub nowszej, aby usunąć tę podatność oraz monitorowanie systemów pod kątem potencjalnych exploitów.

Original NVD description (English source)
In barebox before 2025.01.0, ext4fs_read_symlink has an integer overflow for zalloc (adding one to an le32 variable) via a crafted ext4 filesystem with an inode size of 0xffffffff, resulting in a malloc of zero and resultant memory overwrite, a related issue to CVE-2024-57256.
