Major changes between sudo 1.9.5p2 and 1.9.5p1
* Buildroot: dropped a patch that was included in the release.
* Fixed sudo's setprogname(3) emulation on systems that don't
provide it.
* Fixed a problem with the sudoers log server client where a partial
write to the server could result the sudo process consuming large
amounts of CPU time due to a cycle in the buffer queue. Bug #954.
* Added a missing dependency on libsudo_util in libsudo_eventlog.
Fixes a link error when building sudo statically.
* The user's KRB5CCNAME environment variable is now preserved when
performing PAM authentication. This fixes GSSAPI authentication
when the user has a non-default ccache.
* When invoked as sudoedit, the same set of command line options
are now accepted as for "sudo -e". The -H and -P options are
now rejected for sudoedit and "sudo -e" which matches the sudo
1.7 behavior. This is part of the fix for CVE-2021-3156.
* Fixed a potential buffer overflow when unescaping backslashes
in the command's arguments. Normally, sudo escapes special
characters when running a command via a shell (sudo -s or sudo
-i). However, it was also possible to run sudoedit with the -s
or -i flags in which case no escaping had actually been done,
making a buffer overflow possible. This fixes CVE-2021-3156.

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 http://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 Freenode IRC.
