"According to its banner, the version of CUPS installed on the remote
host is prior to 1.4.5. It is, therefore, affected by multiple
vulnerabilities :

  - A use-after-free error exists due to improper allocation
    of memory for attribute values with invalid string data
    types. A remote attacker can exploit this, via a crafted
    IPP request, to cause a denial of service condition or
    the execution of arbitrary code. (CVE-2010-2941)

  - An overflow condition exists in the PPD compiler due to
    improper validation of user-supplied input. A remote
    attacker can exploit this to dereference already freed
    memory, resulting in the execution of arbitrary code.
