If the value itself has a trailing CR, the normal LF that +follows results in the CR being unintentionally stripped. This may lead +to unintended behavior due to the config value written being different +when it gets read. + +One such issue involves a repository with a submodule path containing a +trailing CR. When the submodule gets initialized, the submodule is +cloned without being checked out and has "core.worktree" set to the +submodule path. The git-checkout(1) that gets spawned later reads the +"core.worktree" config value, but without the trailing CR, and +consequently attempts to checkout to a different path than intended. + +If the repository contains a matching path that is a symlink, it is +possible for the submodule repository to be checked out in arbitrary +locations. This is extra bad when the symlink points to the submodule +hooks directory and the submodule repository contains an executable +"post-checkout" hook. Once the submodule repository checkout completes, +the "post-checkout" hook immediately executes. + +To prevent mismatched config state due to misinterpreting a trailing CR, +wrap config values containing CR in double quotes when writing the +entry. This ensures a trailing CR is always separated for an LF and thus +prevented from getting stripped. + +Note that this problem cannot be addressed by just quoting each CR with +"\r". The reading side of the config interprets only a few backslash +escapes, and "\r" is not among them. This fix is sufficient though +because it only affects the CR at the end of a line and any literal CR +in the interior is already preserved. + +Co-authored-by: David Leadbeater +Signed-off-by: Justin Tobler +Signed-off-by: Taylor Blau +--- + config.c | 2 +- + t/t1300-config.sh | 11 +++++++++++ + t/t7450-bad-git-dotfiles.sh | 33 +++++++++++++++++++++++++++++++++ + 3 files changed, 45 insertions(+), 1 deletion(-) + +diff --git a/config.c b/config.c +index 9ff6ae1cb903a0..629981451d303b 100644 +--- a/config.c ++++ b/config.c +@@ -2999,7 +2999,7 @@ static ssize_t write_pair(int fd, const char *key, const char *value, + if (value[0] == ' ') + quote = "\""; + for (i = 0; value[i]; i++) +- if (value[i] == ';' || value[i] == '#') ++ if (value[i] == ';' || value[i] == '#' || value[i] == '\r') + quote = "\""; + if (i && value[i - 1] == ' ') + quote = "\""; +diff --git a/t/t1300-config.sh b/t/t1300-config.sh +index f4e27521344920..1010410b7e2926 100755 +--- a/t/t1300-config.sh ++++ b/t/t1300-config.sh +@@ -2590,4 +2590,15 @@ test_expect_success 'includeIf.hasconfig:remote.*.url forbids remote url in such + grep "fatal: remote URLs cannot be configured in file directly or indirectly included by includeIf.hasconfig:remote.*.url" err + ' + ++test_expect_success 'writing value with trailing CR not stripped on read' ' ++ test_when_finished "rm -rf cr-test" && ++ ++ printf "bar\r\n" >expect && ++ git init cr-test && ++ git -C cr-test config set core.foo $(printf "bar\r") && ++ git -C cr-test config get core.foo >actual && ++ ++ test_cmp expect actual ++' ++ + test_done +diff --git a/t/t7450-bad-git-dotfiles.sh b/t/t7450-bad-git-dotfiles.sh +index 5b845e899bf17c..20262855664a97 100755 +--- a/t/t7450-bad-git-dotfiles.sh ++++ b/t/t7450-bad-git-dotfiles.sh +@@ -347,4 +347,37 @@ test_expect_success 'checkout -f --recurse-submodules must not use a nested gitd + test_path_is_missing nested_checkout/thing2/.git + ' + ++test_expect_success SYMLINKS,!WINDOWS,!MINGW 'submodule must not checkout into different directory' ' ++ test_when_finished "rm -rf sub repo bad-clone" && ++ ++ git init sub && ++ write_script sub/post-checkout <<-\EOF && ++ touch "$PWD/foo" ++ EOF ++ git -C sub add post-checkout && ++ git -C sub commit -m hook && ++ ++ git init repo && ++ git -C repo -c protocol.file.allow=always submodule add "$PWD/sub" sub && ++ git -C repo mv sub $(printf "sub\r") && ++ ++ # Ensure config values containing CR are wrapped in quotes. ++ git config unset -f repo/.gitmodules submodule.sub.path && ++ printf "\tpath = \"sub\r\"\n" >>repo/.gitmodules && ++ ++ git config unset -f repo/.git/modules/sub/config core.worktree && ++ { ++ printf "[core]\n" && ++ printf "\tworktree = \"../../../sub\r\"\n" ++ } >>repo/.git/modules/sub/config && ++ ++ ln -s .git/modules/sub/hooks repo/sub && ++ git -C repo add -A && ++ git -C repo commit -m submodule && ++ ++ git -c protocol.file.allow=always clone --recurse-submodules repo bad-clone && ++ ! test -f "$PWD/foo" && ++ test -f $(printf "bad-clone/sub\r/post-checkout") ++' ++ + test_done diff --git a/git.spec b/git.spec index 8d4613b..4ff285d 100644 --- a/git.spec +++ b/git.spec @@ -1,3 +1,4 @@ +%define anolis_release .0.1 # Pass --without docs to rpmbuild if you don't want the documentation %bcond_without docs @@ -93,7 +94,7 @@ Name: git Version: 2.43.5 -Release: 3%{?rcrev}%{?dist} +Release: 3%{?rcrev}%{anolis_release}%{?dist} Summary: Fast Version Control System License: GPLv2 URL: https://git-scm.com/ @@ -149,6 +150,7 @@ Patch6: git-2.43.0-slow-shallow-clones.patch # # https://github.com/gitgitgadget/git/pull/1853 Patch7: git-2.43.5-sanitize-sideband-channel-messages.patch +Patch100: 0001-quote-values-containing-CR-character.patch %if %{with docs} # pod2man is needed to build Git.3pm @@ -1111,6 +1113,9 @@ rmdir --ignore-fail-on-non-empty "$testdir" %{?with_docs:%{_pkgdocdir}/git-svn.html} %changelog +* Thu Jul 10 2025 Hong Wei Qin - 2.43.5-3.0.1 +- Fix CVE-2025-48384 + * Fri Apr 04 2025 Ondřej Pohořelský - 2.43.5-3 - add the option to sanitize sideband channel messages - Resolves: RHEL-74177 -- Gitee From a574433352c4943c5b88013da331c894e4f91c38 Mon Sep 17 00:00:00 2001 From: "taifu.gc" Date: Wed, 24 May 2023 10:03:57 +0800 Subject: [PATCH 2/2] Skip some test on aarch64 --- git.spec | 13 +++++++++++++ 1 file changed, 13 insertions(+) diff --git a/git.spec b/git.spec index 4ff285d..c883bd9 100644 --- a/git.spec +++ b/git.spec @@ -921,6 +921,18 @@ GIT_SKIP_TESTS="$GIT_SKIP_TESTS t5300.1[02348] t5300.2[03459] t5300.30 t5300.4[5 %endif # endif rhel == 8 && arch == s390x +%if 0%{?rhel} == 8 && "%{_arch}" == "aarch64" || "%{_arch}" == "x86_64" || "%{_arch}" == "loongarch64" +# Skip tests which fail on aarch64 on anolis-8 +# +# The following tests fail on aarch64 & an8.
