Kerentanan Uncontrolled Resource Consumption pada systemd project systemd, fedoraproject fedora. Skor CVSS 3.1 5.5 (Medium) menurut NVD.

Deskripsi (NVD)

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.
