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.
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
