FKIE_CVE-2015-8872

Vulnerability from fkie_nvd - Published: 2016-06-03 14:59 - Updated: 2026-06-17 00:35
Severity
6.2 (Medium) - CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
The set_fat function in fat.c in dosfstools before 4.0 might allow attackers to corrupt a FAT12 filesystem or cause a denial of service (invalid memory read and crash) by writing an odd number of clusters to the third to last entry on a FAT12 filesystem, which triggers an "off-by-two error."
