1. [20.10] Update go 1.18.7 to address CVE-2022-2879, CVE-2022-2880, CVE… …

   …-2022-41715
   
   From the mailing list:
   
   We have just released Go versions 1.19.2 and 1.18.7, minor point releases.
   
   These minor releases include 3 security fixes following the security policy:
   
   - archive/tar: unbounded memory consumption when reading headers
   
     Reader.Read did not set a limit on the maximum size of file headers.
     A maliciously crafted archive could cause Read to allocate unbounded
     amounts of memory, potentially causing resource exhaustion or panics.
     Reader.Read now limits the maximum size of header blocks to 1 MiB.
   
     Thanks to Adam Korczynski (ADA Logics) and OSS-Fuzz for reporting this issue.
   
     This is CVE-2022-2879 and Go issue https://go.dev/issue/54853.
   
   - net/http/httputil: ReverseProxy should not forward unparseable query parameters
   
     Requests forwarded by ReverseProxy included the raw query parameters from the
     inbound request, including unparseable parameters rejected by net/http. This
     could permit query parameter smuggling when a Go proxy forwards a parameter
     with an unparseable value.
   
     ReverseProxy will now sanitize the query parameters in the forwarded query
     when the outbound request's Form field is set after the ReverseProxy.Director
     function returns, indicating that the proxy has parsed the query parameters.
     Proxies which do not parse query parameters continue to forward the original
     query parameters unchanged.
   
     Thanks to Gal Goldstein (Security Researcher, Oxeye) and
     Daniel Abeles (Head of Research, Oxeye) for reporting this issue.
   
     This is CVE-2022-2880 and Go issue https://go.dev/issue/54663.
   
   - regexp/syntax: limit memory used by parsing regexps
   
     The parsed regexp representation is linear in the size of the input,
     but in some cases the constant factor can be as high as 40,000,
     making relatively small regexps consume much larger amounts of memory.
   
     Each regexp being parsed is now limited to a 256 MB memory footprint.
     Regular expressions whose representation would use more space than that
     are now rejected. Normal use of regular expressions is unaffected.
