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."

Security readout for executives and security teams

CVE-2015-8872 affects dosfstools before 4.0. A specially malformed FAT12 filesystem can make the tool corrupt filesystem metadata or crash while processing it. Business impact is mainly operational disruption when servers, workstations, or automation inspect untrusted removable media or disk images. Exposure is most likely on Linux systems, forensic workflows, build pipelines, or device-management processes that run dosfstools or fsck.vfat against FAT12 media or images, especially untrusted USB media or uploaded disk images. Treat this as a bounded operational-risk issue, not an internet-scale emergency. Prioritize patching where untrusted media or disk images are processed automatically. Standard package updates should be sufficient for most environments. Mitigation focus: Upgrade dosfstools to version 4.0 or a vendor-fixed package.; Apply relevant Ubuntu, openSUSE, Debian, or other distribution security updates.; Check vendor advisories before relying on source-only fixes..
