Descriptions
Divide-by-zero vulnerabilities in the function arlib_add_symbols() in arlib.c in elfutils 0.174 allow remote attackers to cause a denial of service (application crash) with a crafted ELF file, as demonstrated by eu-ranlib, because a zero sh_entsize is mishandled.
Vulnerabilidades de división entre cero en la función arlib_add_symbols() en arlib.c en elfutils 0.174 permiten que los atacantes remotos provoquen una denegación de servicio (cierre inesperado de la aplicación) con un archivo ELF manipulado, tal y como queda demostrado con eu-ranlib. Esto se debe a que se gestiona de manera incorrecta un sh_entsize con valor cero.
