Overview

Affected versions of this package are vulnerable to Buffer Overflow due to insufficient checks in the net/ceph/messenger_v2.c file. An attacker can execute arbitrary code remotely by exploiting a buffer overflow condition. This is caused by an integer signedness error, which leads to an untrusted length being taken from a TCP packet in ceph_decode_32.
