Description

Vulnerability Description

Yellow Dog Linux contains a flaw that may allow a local denial of service. The issue is triggered when the root filesystem is filled to 100% capacity and an unclean shutdown is followed by a forced fsck filesystem check. This will cause the /etc/fstab file to be overwritten with a 0-length file. The system will then be unable to boot, resulting in a loss of availability for the platform.

Solution Description

Currently, there are no known upgrades, patches, or workarounds available to correct this issue.
