NVD Description
Note: Versions mentioned in the description apply only to the upstream tidy-html5 package and not the tidy-html5 package as distributed by Ubuntu.
In Tidy 5.7.0, the prvTidyTidyMetaCharset function in clean.c allows attackers to cause a denial of service (Segmentation Fault), because the currentNode variable in the "children of the head" processing feature is modified in the loop without validating the new value.
