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.

Exploit prediction (EPSS)

1.11% probability of exploitation in the next 30 days, higher than 66% of all scored CVEs.
