"The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has udisks2 packages installed that are affected
by a vulnerability:

  - UDisks 2.8.0 has a format string vulnerability in
    udisks_log in udiskslogging.c, allowing attackers to
    obtain sensitive information (stack contents), cause a
    denial of service (memory corruption), or possibly have
    unspecified other impact via a malformed filesystem
    label, as demonstrated by %d or %n substrings.
