Description Pedro Sampaio 2017-09-15 10:22:45 EDT

The process_version_sections function in readelf.c in GNU Binutils 2.29 allows
attackers to cause a denial of service (Integer Overflow, and hang because of a
time-consuming loop) or possibly have unspecified other impact via a crafted
binary file with invalid values of ent.vn_next, during "readelf -a" execution.
