If you cannot patch yet, avoid extracting CMSIS-Pack archives from untrusted sources or use additional controls to validate pack contents before extraction.
Description
In Eclipse Embedded CDT versions 6.0 to 6.7 if the CMSIS-Pack archive extracts a compromised CMSIS pack the archive extraction can extract files to locations outside of the pack, allowing writing of arbitrary files to other locations on disk.
