Details

It was discovered that libHX incorrectly handled certain parameters to the
HX_split function. An attacker could use this flaw to cause a denial of
service or possibly execute arbitrary code with the privileges of the user.

The default compiler options for affected releases should reduce the
vulnerability to a denial of service.
