elfutils: buffer over-read in ebldynamictagname.c:ebl_dynamic_tag_name() allows for denial of service
elfutils 0.170 has a buffer over-read in the ebl_dynamic_tag_name function of libebl/ebldynamictagname.c because SYMTAB_SHNDX is unsupported.
An out-of-bound read flaw has been found in elfutils in the ebl_dynamic_tag_name function of ebldynamictagname.c file. An attacker could exploit this by supplying a crafted ELF file to display wrong data or potentially cause a crash in eu-readelf and eu-elflint binaries.
