Subject: [PATCH] Fix crash in sudo 1.8.30 when suspending sudo at the password
|
||||
prompt. The closure pointer in sudo_conv_callback was being filled in with a
|
||||
struct getpass_closure ** instead of a struct getpass_closure *. The bug was
|
||||
introduced in the fix for Bug #910; previously the closure variable was a
|
||||
struct getpass_closure, not a pointer. Fix from Michael Norton; Bug #914.

From b54a16e1749fc53e4ed047da72f97b8f99bf4d6a Mon Sep 17 00:00:00 2001

From: "Todd C. Miller" <Todd.Miller@sudo.ws>
|

Date: Fri, 9 Jul 2021 11:08:44 -0600
|
||||
Subject: [PATCH] Add support for logging exit status events. For
|
||||
sudo-formatted logs, this is a record with "EXIT=number" and potentially
|
||||
"SIGNAL=name" after the command. For JSON-format logs, a new "exit" record
|
||||
is logged which contains an "exit_value" and potentially "signal" and
|
||||
"core_dumped". JSON-format logs now incude a UUID to associate the "exit"
|
||||
record with the "accept" record.

Subject: [PATCH] Fix potential directory existing info leak in sudoedit. When
|
||||
creating a new file, sudoedit checks to make sure the parent directory exists
|
||||
so it can provide the user with a sensible error message. However, this
|
||||
could be used to test for the existence of directories not normally
|
||||
accessible to the user by pointing to them with a symbolic link when the
|
||||
parent directory is controlled by the user. Problem reported by Matthias
|
||||
Gerstner of SUSE.

Subject: [PATCH] Extend the original file before to the new size before

updating it. Instead of opening the original file for writing w/ tuncation,

we first extend the file with zeroes (by writing, not seeking), then

overwrite it. This should allow sudo to fail early if the disk is out of

space before it overwrites the original file.

Subject: [PATCH] Fixed bad condition for sesh args
|
||||
|
||||
In selinux_edit_copy_tfiles() when there is only one file and the open()
|
||||
fails then number of arguments is lower than expected.
|
||||
Sudo should return error with or without "Defaults !sudoedit_checkdir" set.
|
||||
|
||||
This was found with regression testing of CVE-2021-23240.

Subject: [PATCH] Make sure SIGCHLD is not ignored when sudo is executed. If
|
||||
SIGCHLD is ignored there is a race condition between when the process is
|
||||
executed and when the SIGCHLD handler is installed. This fixes the bug
|
||||
described by GitHub PR #98
