CVE-2015-8872: Canonical Ubuntu Linux

Medium severity, CVSS 6.2. EPSS: 0.4% chance of exploitation in the next 30 days.

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."

Affected products

• Canonical Ubuntu Linux: version 12.04 only; version 14.04 only; version 15.10 only; version 16.04 only
• Dosfstools Project Dosfstools: up to and including 3.0.28
