Title: MATLAB Mex Insecure Temporary Files Vulnerability
Severity: MODERATE
Description:
MATLAB is a language and technical computing environment. It is available for a number of platforms, including Linux and Unix variants and Microsoft Windows.
MATLAB is prone to an issue which may allow local attackers to corrupt files.
The MATLAB Mex script uses the process ID (PID) when naming temporary files. If an attacker can anticipate the name of temporary files created by Mex, then the attacker can place a malicious symbolic link in place of the temporary files. If the symbolic link points to a file which is writeable by the user running the program, then they will be corrupted when the Mex script performs any actions on temporary files.
This may result in critical files being overwritten. If an attacker can cause files to be overwritten with custom data, then it may be possible to elevate privileges.
Affected Products:
- MathWorks MATLAB 6.5.0
