CVE-2015-8872 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:15.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream dosfstools package and not the dosfstools package as distributed by Ubuntu.
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."
