+Subject: [PATCH] language: reject excessively large Accept-Language strings
+
+Backported to apply on vendor direcotry by @mfrw
+
+The BCP 47 tag parser has quadratic time complexity due to inherent
+aspects of its design. Since the parser is, by design, exposed to
+untrusted user input, this can be leveraged to force a program to
+consume significant time parsing Accept-Language headers.
+
+The parser cannot be easily rewritten to fix this behavior for
+various reasons. Instead the solution implemented in this CL is to
+limit the total complexity of tags passed into ParseAcceptLanguage
+by limiting the number of dashes in the string to 1000. This should
+be more than enough for the majority of real world use cases, where
+the number of tags being sent is likely to be in the single digits.
+
+Thanks to the OSS-Fuzz project for discovering this issue and to Adam
+Korczynski (ADA Logics) for writing the fuzz case and for reporting the
+issue.
+
+Fixes CVE-2022-32149
+Fixes golang/go#56152
