CVE-2015-8872
Last modified
CVE-2015-8872 is a vulnerability of currently unknown severity. 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.". EPSS estimates a 0.43% chance of exploitation in the next 30 days.
