Descriptions

In elfutils 0.175, there is a buffer over-read in the ebl_object_note function in eblobjnote.c in libebl. Remote attackers could leverage this vulnerability to cause a denial-of-service via a crafted elf file, as demonstrated by eu-readelf.

En la versión 0.175 de elfutils hay una sobrelectura de búfer en la función ebl_object_note en eblobjnote.c en libebl. Los atacantes remotos pueden aprovechar esta vulnerabilidad para provocar una denegación de servicio (DoS) mediante un archivo elf manipulado, tal y como queda demostrado con eu-readelf.
