Description Andrej Nemec 2017-11-21 09:54:23 UTC
elfcomm.c in readelf in GNU Binutils 2.29 allows remote attackers to cause a denial of service (excessive memory allocation) or possibly have unspecified other impact via a crafted ELF file that triggers a "buffer overflow on fuzzed archive header," related to an uninitialized variable, an improper conditional jump, and the get_archive_member_name, process_archive_index_and_symbols, and setup_archive functions.
