Kevin B. McCarty discovered that the feynmf.pl script creates a |
| 46 |
temporary "properly list" file at the location "$TMPDIR/feynmf$PID.pl", |
| 47 |
where $PID is the process ID. |

<p> |
| 52 |
A local attacker could create symbolic links in the directory where the |
| 53 |
temporary files are written, pointing to a valid file somewhere on the |
| 54 |
filesystem that is writable by the user running Feynmf. When Feynmf |
| 55 |
writes the temporary file, the target valid file would then be |
| 56 |
overwritten with the contents of the Feynmf temporary file. |

All Feynmf users should upgrade to the latest version: |
