Title
marcobambini Gravity Number gravity_parser.c parse_number_expression out-of-bounds
Summary
A vulnerability was detected in marcobambini Gravity up to 0.9.7. This impacts the function parse_number_expression of the file src/compiler/gravity_parser.c of the component Number Parser. Performing a manipulation results in out-of-bounds read. It is possible to initiate the attack remotely. The exploit is now public and may be used. Upgrading to version 0.9.8 will fix this issue. The patch is named 1b9bbf3ad5749e2a3434e6ad073c6e93c24207b6. It is recommended to upgrade the affected component.
