    Summary: Updated libksba packages fix security vulnerability

    Details: It was found that an unproportionate amount of memory is allocated when parsing crafted certificates in libskba, which may lead to DoS. Moreover in libksba 1.3.4, allocated memory is uninitialized and could potentially contain sensitive data left in freed memory block.
