Описание
In the Linux kernel, the following vulnerability has been resolved:
libceph: prevent potential out-of-bounds writes in handle_auth_session_key()
The len field originates from untrusted network packets. Boundary
checks have been added to prevent potential out-of-bounds writes when
decrypting the connection secret or processing service tickets.
[ idryomov: changelog ]
An out-of-bounds write vulnerability was found in the Ceph authentication handling code in the Linux kernel. The handle_auth_session_key() function uses a length field from network packets without proper validation, potentially allowing out-of-bounds memory writes during connection secret decryption or service ticket processing.
Отчет
A malicious Ceph monitor or man-in-the-middle attacker could exploit this by sending specially crafted authentication responses. Systems using CephFS or RBD are potentially affected.
