D-Bus 1.8.8 (UNRELEASED) D-Bus 1.8.8 (2014-09-16)
== ==
Fixes: The "smashy smashy egg man" release.
Security fixes:
• Do not accept an extra fd in the padding of a cmsg message, which
could lead to a 4-byte heap buffer overrun.
(CVE-2014-3635, fd.o #83622; Simon McVittie)
• Reduce default for maximum Unix file descriptors passed per message
from 1024 to 16, preventing a uid with the default maximum number of
connections from exhausting the system bus' file descriptors under
Linux's default rlimit. Distributors or system administrators with a
more restrictive fd limit may wish to reduce these limits further.
Additionally, on Linux this prevents a second denial of service
in which the dbus-daemon can be made to exceed the maximum number
of fds per sendmsg() and disconnect the process that would have
received them.
(CVE-2014-3636, fd.o #82820; Alban Crequy)
• Disconnect connections that still have a fd pending unmarshalling after
a new configurable limit, pending_fd_timeout (defaulting to 150 seconds),
removing the possibility of creating an abusive connection that cannot be
disconnected by setting up a circular reference to a connection's
file descriptor.
(CVE-2014-3637, fd.o #80559; Alban Crequy)
• Reduce default for maximum pending replies per connection from 8192 to 128,
mitigating an algorithmic complexity denial-of-service attack
(CVE-2014-3638, fd.o #81053; Alban Crequy)
• Reduce default for authentication timeout on the system bus from
30 seconds to 5 seconds, avoiding denial of service by using up
all unauthenticated connection slots; and when all unauthenticated
connection slots are used up, make new connection attempts block
instead of disconnecting them.
(CVE-2014-3639, fd.o #80919; Alban Crequy)
