Summary
GMT is an open source collection of command-line tools for manipulating geographic and Cartesian data sets. In versions from 6.6.0 and prior, a stack-based buffer overflow vulnerability was identified in the gmt_remote_dataset_id function within src/gmt_remote.c. This issue occurs when a specially crafted long string is passed as a dataset identifier (e.g., via the which module), leading to a crash or potential arbitrary code execution. This issue has been patched via commit 0ad2b49.
