Changes since OpenSSH 10.3
==========================
This release contains a number of security fixes as well as general
bugfixes and a couple of new features.
Security
========
* sftp(1): when downloading files on the command-line using
"sftp host:/path .", a malicious server could cause the file to
be downloaded to an unexpected location. This issue was identified
by the Swival Security Scanner.
* scp(1): when copying files between two remote destinations, do
not allow a malicious server to write files to the parent
directory of the intended target directory. This issue was
identified by the Swival Security Scanner.
* sshd(8): when using the "internal-sftp" SFTP server implementation
(this is not the default), long command lines were previously
truncated silently after the 9th argument. If a security-relevant
option was in the 10th or later position, it would be discarded.
Reported by Steve Caffrey.
* sshd(8): add a documentation note to mention that the
GSSAPIStrictAcceptorCheck option is ineffective when the server
is joined to a Windows Active Directory. Reported by Yarin Aharoni
of Safebreach.
* sshd(8): DisableForwarding=yes didn't override PermitTunnel=yes
as it was documented to do. Note that PermitTunnel is not enabled
by default. Reported independently by Huzaifa Sidhpurwala of
Redhat and Marko Jevtic.
* sshd(8): avoid a potential pre-authentication denial of service
when GSSAPIAuthentication was enabled (this feature is off by
default). This was not mitigated by MaxAuthTries, but would be
penalised by PerSourcePenalties. This was reported by Manfred
Kaiser of the milCERT AT (Austrian Ministry of Defence).
* sshd(8): fix a number of cases where the minimum authentication
delay was not being enforced. Reported by the Orange Cyberdefense
Vulnerability Team.
* ssh(1): fix a possible client-side use-after-free if the server
changes its host key during a key reexchange. This was reported by
Zhenpeng (Leo) Lin of Depthfirst.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at https://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
