DWARF Section Length Field Vulnerability in GNU Debugger (GDB)

CVE-2017-9778 · MEDIUM Severity

AV:N/AC:M/AU:N/C:N/I:N/A:P

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.
