Description GLSAMaker/CVETool Bot gentoo-dev 2017-10-27 00:03:24 UTC
CVE-2017-9778 (
  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.

@Maintainers 8.0.1 is already in tree, call for stabilization when ready please.

Thank you

Issue is extremely minor and no upstream patch available addressing the issue.  The concern here could be malware that causes a crash when attempts to debug it are made.
