Secunia Advisory SA39805

Where:

Local system

Impact:

Privilege escalation

Solution Status:

Unpatched

CVE Reference(s):

Description


Paul Szabo has reported some security issues in Mathematica, which can be exploited by malicious, local users to potentially gain escalated privileges.

The application uses temporary files in the /tmp/MathLink directory in an insecure manner. This can be exploited to create world writable files in normally restricted directories or corrupt restricted files via symlink attacks.

NOTE: An insecure usage of the /tmp/fonts$$.conf file was also reported.

The security issues are reported in Mathematica 7 and 8 for Linux. Other Linux versions may also be affected.


Solution:
Restrict local access to trusted users only. Do not run Mathematica as root.

Paul Szabo
