CVE-2017-9778

GNU Debugger (GDB) 8.0 and earlier fails to detect a negative length field in a DWARF section.

MEDIUM 5.5EPSS 1.11%

Does this matter?

Lower severity and a low EPSS score (1.11%). Track it; it rarely justifies an emergency change on its own.

Description

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.
