This change causes Clean to insert a . +path element at the start of a path when the original path does not +start with a volume name, and the first path element would contain +a colon. + +This may introduce a spurious but harmless . path element under +some circumstances. For example, Clean("a/../b:/../c") becomes `.\c`. + +This reverts CL 401595, since the change here supersedes the one +in that CL. + +Thanks to RyotaK (https://twitter.com/ryotkak) for reporting this issue. + +Updates #57274 +Fixes #57276 +Fixes CVE-2022-41722 + +Change-Id: I837446285a03aa74c79d7642720e01f354c2ca17 +Reviewed-on: https://team-review.git.corp.google.com/c/golang/go-private/+/1675249 +Reviewed-by: Roland Shoemaker <bracewell@google.com> +Run-TryBot: Damien Neil <dneil@google.com> +Reviewed-by: Julie Qiu <julieqiu@google.com> +TryBot-Result: Security TryBots <security-trybots@go-security-trybots.iam.gserviceaccount.com> +(cherry picked from commit 8ca37f4813ef2f64600c92b83f17c9f3ca6c03a5) +Reviewed-on: https://team-review.git.corp.google.com/c/golang/go-private/+/1728944 +Run-TryBot: Roland Shoemaker <bracewell@google.com> +Reviewed-by: Tatiana Bradley <tatianabradley@google.com> +Reviewed-by: Damien Neil <dneil@google.com> +Reviewed-on: https://go-review.googlesource.com/c/go/+/468119 +Reviewed-by: Than McIntosh <thanm@google.com> +Run-TryBot: Michael Pratt <mpratt@google.com> +TryBot-Result: Gopher Robot <gobot@golang.org> +Auto-Submit: Michael Pratt <mpratt@google.com> + +Upstream-Status: Backport from https://github.com/golang/go/commit/bdf07c2e168baf736e4c057279ca12a4d674f18c +CVE: CVE-2022-41722 +Signed-off-by: Shubham Kulkarni <skulkarni@mvista.com> +--- + src/path/filepath/path.go | 27 ++++++++++++++------------- + 1 file changed, 14 insertions(+), 13 deletions(-) + +diff --git a/src/path/filepath/path.go b/src/path/filepath/path.go +index 92dc090..f0f095e 100644 +--- a/src/path/filepath/path.go ++++ b/src/path/filepath/path.go +@@ -14,6 +14,7 @@ package filepath + import ( + "errors" + "os" ++ "runtime" + "sort" + "strings" + ) +@@ -116,21 +117,9 @@ func Clean(path string) string { + case os.IsPathSeparator(path[r]): + // empty path element + r++ +- case path[r] == '.' && r+1 == n: ++ case path[r] == '.' && (r+1 == n || os.IsPathSeparator(path[r+1])): + // . element + r++ +- case path[r] == '.' && os.IsPathSeparator(path[r+1]): +- // ./ element +- r++ +- +- for r < len(path) && os.IsPathSeparator(path[r]) { +- r++ +- } +- if out.w == 0 && volumeNameLen(path[r:]) > 0 { +- // When joining prefix "." and an absolute path on Windows, +- // the prefix should not be removed. +- out.append('.') +- } + case path[r] == '.' && path[r+1] == '.' && (r+2 == n || os.IsPathSeparator(path[r+2])): + // .. element: remove to last separator + r += 2 +@@ -156,6 +145,18 @@ func Clean(path string) string { + if rooted && out.w != 1 || !rooted && out.w != 0 { + out.append(Separator) + } ++ // If a ':' appears in the path element at the start of a Windows path, ++ // insert a .\ at the beginning to avoid converting relative paths ++ // like a/../c: into c:. ++ if runtime.GOOS == "windows" && out.w == 0 && out.volLen == 0 && r != 0 { ++ for i := r; i < n && !os.IsPathSeparator(path[i]); i++ { ++ if path[i] == ':' { ++ out.append('.') ++ out.append(Separator) ++ break ++ } ++ } ++ } + // copy element + for ; r < n && !os.IsPathSeparator(path[r]); r++ { + out.append(path[r]) +-- +2.7.4 |
