MEDIUMGDB < 8.0 - Denial of Service via Negative DWARF Section Length
Title source: llmDescription
GNU Debugger (GDB) 8.0 and earlier fails to detect a negative length field in a DWARF section. A malformed section in an ELF binary or a core file can cause GDB to repeatedly allocate memory until a process limit is reached. This can, for example, impede efforts to analyze malware with GDB.
