CVE-2017-9778 (GCVE-0-2017-9778)

Vulnerability from cvelistv5 – Published: 2017-06-21 07:00 – Updated: 2024-08-05 17:18

Summary

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.

Severity ?
