Assigned:2014-09-15
Published:2014-09-15
Updated:2023-01-17
Summary:Linux Kernel libceph is vulnerable to a buffer overflow, caused by improper bounds checking by the auth ticket size. By sending an overly large amount of tickets, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause a denial of service.
