Description Andrej Nemec 2017-06-29 07:07:50 EDT
GNU Debugger (GDB) 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.
