MySQL extension automatic porting to PDO for PHP migration and security improvement

In software management, the upgrade of programming languages may introduce critical issues. This is the case of PHP, the fifth version of which is going towards the end of the support. The new release improves on different aspects, but removes the old deprecated MySQL extensions, and supports only the newer library of functions for the connection to the databases. The software systems already in place need to be renewed to be compliant with respect to the new language version. The conversion of the source code, to be safe against injection attacks, should involve also the transformation of the query code. The purpose of this work is the design of specific tool that automatically applies the required transformation yielding to a precise and efficient conversion procedure. The tool has been applied to different projects to provide evidence of its effectiveness

Automatic Error Elimination by Multi-Application Code Transfer

We present pDNA, a system for automatically transfer- ring correct code from donor applications into recipient applications to successfully eliminate errors in the recipient. Experimental results using six donor applications to eliminate nine errors in six recipient applications highlight the ability of pDNA to transfer code across applications to eliminate otherwise fatal integer and buffer overflow errors. Because pDNA works with binary donors with no need for source code or symbolic information, it supports a wide range of use cases. To the best of our knowledge, pDNA is the first system to eliminate software errors via the successful transfer of correct code across applications

Automatic Error Elimination by Multi-Application Code Transfer

We present pDNA, a system for automatically transferring correct code from donor applications into recipient applications to successfully eliminate errors in the recipient. Experimental results using three donor applications to eliminate seven errors in four recipient applications highlight the ability of pDNA to transfer code across applications to eliminate otherwise fatal integer overflow errors at critical memory allocation sites. Because pDNA works with binary donors with no need for source code or symbolic information, it supports a wide range of use cases. To the best of our knowledge, pDNA is the first system to eliminate software errors via the successful transfer of correct code across applications

Automatic Error Elimination by Multi-Application Code Transfer

We present Code Phage (CP), a system for automatically transferring correct code from donor applications into recipient applications to successfully eliminate errors in the recipient. Experimental results using six donor applications to eliminate nine errors in six recipient applications highlight the ability of CP to transfer code across applications to eliminate otherwise fatal integer and buffer over- flow errors. Because CP works with binary donors with no need for source code or symbolic information, it supports a wide range of use cases. To the best of our knowledge, CP is the first system to eliminate software errors via the successful transfer of correct code across applications
