upstream patches (Closes: #
1024932).
[ Bastien Roucariès ]
* CVE-2021-3979:
A key length flaw was found. An attacker can exploit the
fact that the key length is incorrectly passed in an
encryption algorithm to create a non random key,
which is weaker and can be exploited for loss of
confidentiality and integrity on encrypted disks.
* CVE-2023-43040 rgw: Fix bucket validation against POST policies
(Closes: #
1053690)
* CVE-2025-52555: an unprivileged user can escalate to root
privileges in a ceph-fuse mounted CephFS by chmod 777
a directory owned by root to gain access. The result
of this is that a user could read, write and execute
to any directory owned by root as long as they chmod
777 it. This impacts confidentiality, integrity, and availability.
