Background
The dwarves package is a utility collection that provides various tools for working with DWARF debugging information. It is commonly used in AlmaLinux 8. DWARF is a debugging format used by many compilers and debuggers to store information about programs. The package includes tools for examining and manipulating DWARF information. However, a vulnerability has been discovered in the dwarves package that could potentially allow attackers to execute arbitrary code or cause a denial of service.
