Description

A DoS could be triggered via a buffer overflow due to the implementation of shading or tinting when converting to pstricks. The problem is a result of handling an unknown color when tinting or shading which lead to an incorrect offset and an eventual DoS. The patch for remediation is: https://sourceforge.net/p/mcj/fig2dev/ci/639c36010a120e97a6e82e7cd57cbf9dbf4b64f1/ |
