"value": "An attempted excessive memory allocation was discovered in the function read_long_names in elf_begin.c in libelf in elfutils 0.174. Remote attackers could leverage this vulnerability to cause a denial-of-service via crafted elf input, which leads to an out-of-memory exception. NOTE: The maintainers believe this is not a real issue, but instead a \"warning caused by ASAN because the allocation is big. By setting ASAN_OPTIONS=allocator_may_return_null=1 and running the reproducer, nothing happens.\""

Los atacantes remotos podr\u00edan aprovechar esta vulnerabilidad para provocar una denegaci\u00f3n de servicio (DoS) mediante entradas elf manipuladas, lo que conduce a una excepci\u00f3n fuera de memoria. NOTA: Los mantenedores creen que este no es un fallo real, sino un \"aviso provocado por ASAN debido a que la asignaci\u00f3n es grande. Al establecer SAN_OPTIONS=allocator_may_return_null=1 y ejecutar el reproductor, no ocurre nada\""
