Updated libksba packages fix security vulnerabilities:
An out-of-bounds read access in ksbadntostr() in libksba 1.3.3, due to an incomplete fix for CVE-2016-4356, could result in denial of service (CVE-2016-4574).
In liksba 1.3.3, the returned length of the object from ksbaberparsetl() (ti.length) was not always checked against the actual buffer length, thus leading to a read access after the end of the buffer, which could result in denial of service (CVE-2016-4579).
