Mono System.CodeDom.Compiler Class Insecure Temporary File Creation Vulnerability

The Mono 'System.CodeDom.Compiler' class creates temporary files in an insecure manner.

An attacker with local access could potentially exploit this issue to perform symlink attacks, overwriting arbitrary files in the context of the affected application.

Successfully exploiting a symlink attack may allow an attacker to overwrite or corrupt sensitive files. This may result in a denial of service; other attacks may also be possible.

Versions 1.0 and 2.0 are vulnerable; other versions may also be affected.
