[tor-browser/tor-browser-87.0-10.5-1] Bug 19273: Avoid JavaScript patching of the external app helper dialog.
by sysrqb＠torproject.org 24 Mar '21

commit a13003823b4b7a0ff5bb1b7826f2827c829a6cb4 Author: Kathy Brade <brade(a)pearlcrescent.com> Date: Tue Jun 28 15:13:05 2016 -0400 Bug 19273: Avoid JavaScript patching of the external app helper dialog. When handling an external URI or downloading a file, invoke Torbutton's external app blocker component (which will present a download warning dialog unless the user has checked the "Automatically download files from now on" box). For e10s compatibility, avoid using a modal dialog and instead use a callback interface (nsIHelperAppWarningLauncher) to allow Torbutton to indicate the user's desire to cancel or continue each request. Other bugs fixed: Bug 21766: Crash with e10s enabled while trying to download a file Bug 21886: Download is stalled in non-e10s mode Bug 22471: Downloading files via the PDF viewer download button is broken Bug 22472: Fix FTP downloads when external helper app dialog is shown Bug 22610: Avoid crashes when canceling external helper app downloads Bug 22618: Downloading pdf file via file:/// is stalling --- .../exthandler/nsExternalHelperAppService.cpp | 172 ++++++++++++++++++--- uriloader/exthandler/nsExternalHelperAppService.h | 3 + .../exthandler/nsIExternalHelperAppService.idl | 47 ++++++ 3 files changed, 204 insertions(+), 18 deletions(-) diff --git a/uriloader/exthandler/nsExternalHelperAppService.cpp b/uriloader/exthandler/nsExternalHelperAppService.cpp index 92927822d792..c02a03d27d2c 100644 --- a/uriloader/exthandler/nsExternalHelperAppService.cpp +++ b/uriloader/exthandler/nsExternalHelperAppService.cpp @@ -133,6 +133,9 @@ static const char NEVER_ASK_FOR_SAVE_TO_DISK_PREF[] = static const char NEVER_ASK_FOR_OPEN_FILE_PREF[] = "browser.helperApps.neverAsk.openFile";

commit d482a11a90e93c9bc2e7da01174bc62594c5fd47 Author: Georg Koppen <gk(a)torproject.org> Date: Wed Apr 20 14:34:50 2016 +0000 Bug 18821: Disable libmdns for Android and Desktop There should be no need to remove the OS X support introduced in https://bugzilla.mozilla.org/show_bug.cgi?id=1225726 as enabling this is governed by a preference (which is actually set to `false`). However, we remove it at build time as well (defense in depth). This is basically a backout of the relevant passages of https://hg.mozilla.org/mozilla-central/rev/6bfb430de85d, https://hg.mozilla.org/mozilla-central/rev/609b337bf7ab and https://hg.mozilla.org/mozilla-central/rev/8e092ec5fbbd.

[tor-browser/tor-browser-87.0-10.5-1] Bug 13379: Sign our MAR files.

commit e9c42862544aeb284980074701e5a12107be8fcb Author: Kathy Brade <brade(a)pearlcrescent.com> Date: Wed Dec 17 16:37:11 2014 -0500 Bug 13379: Sign our MAR files. Configure with --enable-verify-mar (when updating, require a valid signature on the MAR file before it is applied). Use the Tor Browser version instead of the Firefox version inside the MAR file info block (necessary to prevent downgrade attacks). Use NSS on all platforms for checking MAR signatures (instead of using OS-native APIs, which Mozilla does on Mac OS and Windows). So that the NSS and NSPR libraries the updater depends on can be found at runtime, we add the firefox directory to the shared library search path on macOS. On Linux, rpath is used by Mozilla to solve that problem, but that approach won't work on macOS because the updater executable is copied during the update process to a location that is under TorBrowser-Data, and the location of TorBrowser-Data varies. Also includes the fix for bug 18900. --- .mozconfig | 1 + .mozconfig-asan | 1 + .mozconfig-mac | 1 + .mozconfig-mingw | 1 + modules/libmar/tool/mar.c | 6 +-- modules/libmar/tool/moz.build | 12 ++++-- modules/libmar/verify/moz.build | 14 +++--- .../mozapps/update/updater/updater-common.build | 26 +++++++++-- toolkit/mozapps/update/updater/updater.cpp | 25 +++++++---- toolkit/xre/moz.build | 3 ++ toolkit/xre/nsUpdateDriver.cpp | 50 ++++++++++++++++++++++ 11 files changed, 115 insertions(+), 25 deletions(-) diff --git a/.mozconfig b/.mozconfig index 18cd1f9b6487..c50c57d410de 100755 --- a/.mozconfig +++ b/.mozconfig @@ -37,3 +37,4 @@ ac_add_options MOZ_TELEMETRY_REPORTING= ac_add_options --disable-tor-launcher ac_add_options --with-tor-browser-version=dev-build ac_add_options --disable-tor-browser-update +ac_add_options --enable-verify-mar diff --git a/.mozconfig-asan b/.mozconfig-asan index bad7ea022c9f..e42ff6c86bc5 100644 --- a/.mozconfig-asan +++ b/.mozconfig-asan @@ -29,6 +29,7 @@ ac_add_options --enable-official-branding ac_add_options --enable-default-toolkit=cairo-gtk3 ac_add_options --enable-tor-browser-update +ac_add_options --enable-verify-mar ac_add_options --disable-strip ac_add_options --disable-install-strip diff --git a/.mozconfig-mac b/.mozconfig-mac index 26e2b6b92fdb..5b4624ef1f67 100644 --- a/.mozconfig-mac +++ b/.mozconfig-mac @@ -43,6 +43,7 @@ ac_add_options --disable-debug ac_add_options --enable-tor-browser-data-outside-app-dir ac_add_options --enable-tor-browser-update +ac_add_options --enable-verify-mar ac_add_options --disable-crashreporter ac_add_options --disable-webrtc diff --git a/.mozconfig-mingw b/.mozconfig-mingw index 3ec6ff18a3e9..ce6ace1dad67 100644 --- a/.mozconfig-mingw +++ b/.mozconfig-mingw @@ -15,6 +15,7 @@ ac_add_options --enable-strip ac_add_options --enable-official-branding ac_add_options --enable-tor-browser-update +ac_add_options --enable-verify-mar ac_add_options --disable-bits-download # Let's make sure no preference is enabling either Adobe's or Google's CDM. diff --git a/modules/libmar/tool/mar.c b/modules/libmar/tool/mar.c index 0bf2cb4bd1d4..ea2b79924914 100644 --- a/modules/libmar/tool/mar.c +++ b/modules/libmar/tool/mar.c @@ -65,7 +65,7 @@ static void print_usage() { "signed_input_archive.mar base_64_encoded_signature_file " "changed_signed_output.mar\n");

commit e8f51b4501d2f031dd409a5e8577bc785a12787c Author: Georg Koppen <gk(a)torproject.org> Date: Mon May 22 12:44:40 2017 +0000 Bug 16285: Exclude ClearKey system for now In the past the ClearKey system had not been compiled when specifying --disable-eme. But that changed and it is even bundled nowadays (see: Mozilla's bug 1300654). We don't want to ship it right now as the use case for it is not really visible while the code had security vulnerabilities in the past. --- browser/installer/package-manifest.in | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/browser/installer/package-manifest.in b/browser/installer/package-manifest.in index 667da5835b9b..b752f985c4c2 100644 --- a/browser/installer/package-manifest.in +++ b/browser/installer/package-manifest.in @@ -473,8 +473,8 @@ bin/libfreebl_64int_3.so #endif ; media -@RESPATH@/gmp-clearkey/0.1/@DLL_PREFIX@clearkey@DLL_SUFFIX@ -@RESPATH@/gmp-clearkey/0.1/manifest.json +;@RESPATH@/gmp-clearkey/0.1/@DLL_PREFIX@clearkey@DLL_SUFFIX@ +;@RESPATH@/gmp-clearkey/0.1/manifest.json #ifdef MOZ_DMD ; DMD
