"value": "systemd 250 and 251 allows local users to achieve a systemd-coredump deadlock by triggering a crash that has a long backtrace. This occurs in parse_elf_object in shared/elf-util.c. The exploitation methodology is to crash a binary calling the same function recursively, and put it in a deeply nested directory to make its backtrace large enough to cause the deadlock. This must be done 16 times when MaxConnections=16 is set for the systemd/units/systemd-coredump.socket file."

Esto ocurre en parse_elf_object enshared/elf-util.c. La metodolog\u00eda de explotaci\u00f3n consiste en bloquear un binario que llama a la misma funci\u00f3n de forma recursiva y colocarlo en un directorio profundamente anidado para que su seguimiento sea lo suficientemente grande como para provocar el punto muerto. Esto se debe hacer 16 veces cuando se establece MaxConnections=16 para el archivo systemd/units/systemd-coredump.socket."
