(Mono: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Mono and Mono debugger.
      Please review the CVE identifiers referenced below for details.
  
Impact :

    A remote attacker could execute arbitrary code, bypass general
      constraints, obtain the source code for .aspx applications, obtain other
      sensitive information, cause a Denial of Service, modify internal data
      structures, or corrupt the internal state of the security manager.
    A local attacker could entice a user into running Mono debugger in a
      directory containing a specially crafted library file to execute
      arbitrary code with the privileges of the user running Mono debugger.
    A context-dependent attacker could bypass the authentication mechanism
      provided by the XML Signature specification.
  
Workaround :

    There is no known workaround at this time."
