    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.

    Thanks to Adam Korczynski (ADA Logics) and OSS-Fuzz for reporting this issue.

    This is CVE-2022-41715 and Go issue https://go.dev/issue/55949.

Please bump to 1.18.7 and 1.19.2.
