Description

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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
