+Subject: [PATCH] cookie: cookie parser out of boundary memory access
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Upstream-Status: Backport
+
+The internal libcurl function called sanitize_cookie_path() that cleans
+up the path element as given to it from a remote site or when read from
+a file, did not properly validate the input. If given a path that
+consisted of a single double-quote, libcurl would index a newly
+allocated memory area with index -1 and assign a zero to it, thus
+destroying heap memory it wasn't supposed to.
