Sebastian Krahmer of the SuSE security team discovered that the
System.CodeDom.Compiler classes used temporary files in an insecure
way. This could allow a symbolic link attack to create or overwrite
arbitrary files with the privileges of the user invoking the program.
Under some circumstances, a local attacker could also exploit this to
inject arbitrary code into running Mono processes.
