Security update for go1.18-openssl

This update for go1.18-openssl fixes the following issues:

  • Add subpackage go1.x-libstd compiled shared object libstd.so (jsc#PED-1962)

    • Main go1.x package included libstd.so in previous versions
    • Split libstd.so into subpackage that can be installed standalone
    • Continues the slimming down of main go1.x package by 40 Mb
    • Experimental and not recommended for general use, Go currently has no ABI
    • Upstream Go has not committed to support buildmode=shared long-term
    • Do not use in packaging, build static single binaries (the default)
    • Upstream Go go1.x binary releases do not include libstd.so
    • go1.x Suggests go1.x-libstd so not installed by default Recommends
    • go1.x-libstd does not Require: go1.x so can install standalone
    • Provides go-libstd unversioned package name
    • Fix build step -buildmode=shared std to omit -linkshared
  • Packaging improvements:

    • go1.x Suggests go1.x-doc so not installed by default Recommends
    • Use Group: Development/Languages/Go instead of Other
  • Improvements to go1.x packaging spec:

    • On Tumbleweed bootstrap with current default gcc13 and gccgo118
    • On SLE-12 aarch64 ppc64le ppc64 remove overrides to bootstrap using go1.x package (%bcond_without gccgo). This is no longer needed on current SLE-12:Update and removing will consolidate the build configurations used.
    • Change source URLs to go.dev as per Go upstream
    • On x86_64 export GOAMD64=v1 as per the current baseline. At this time forgo GOAMD64=v3 option for x86_64_v3 support.
    • On x86_64 %define go_amd64=v1 as current instruction baseline
  • Update to version 1.18.10.1 cut from the go1.18-openssl-fips branch at the revision tagged go1.18.10-1-openssl-fips.

    • Merge branch dev.boringcrypto.go1.18 into go1.18-openssl-fips
    • Merge go1.18.10 into dev.boringcrypto.go1.18
  • go1.18.10 (released 2023-01-10) includes fixes to cgo, the compiler, the linker, and the crypto/x509, net/http, and syscall packages. Refs bsc#1193742 go1.18 release tracking

    • go#57705 misc/cgo: backport needed for dlltool fix
    • go#57426 crypto/x509: Verify on macOS does not return typed errors
    • go#57344 cmd/compile: the loong64 intrinsic for CompareAndSwapUint32 function needs to sign extend its 'old' argument.
    • go#57338 syscall, internal/poll: accept4-to-accept fallback removal broke Go code on Synology DSM 6.2 ARM devices
    • go#57213 os: TestLstat failure on Linux Aarch64
    • go#57211 reflect: sort.SliceStable sorts incorrectly on arm64 with less function created with reflect.MakeFunc and slice of sufficient length
    • go#57057 cmd/go: remove test dependency on gopkg.in service
    • go#57054 cmd/go: TestScript/version_buildvcs_git_gpg (if enabled) fails on linux longtest builders
    • go#57044 cgo: malformed DWARF TagVariable entry
    • go#57028 cmd/cgo: Wrong types in compiler errors with clang 14
    • go#56833 cmd/link/internal/ppc64: too-far trampoline is reused
    • go#56711 net: reenable TestLookupDotsWithRemoteSource and TestLookupGoogleSRV with a different target
    • go#56323 net/http: bad handling of HEAD requests with a body

Requests forwarded by ReverseProxy include the raw query parameters from the inbound request, including unparsable parameters rejected by net/http. This could permit query parameter smuggling when a Go proxy forwards a parameter with an unparsable value. After fix, ReverseProxy sanitizes 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.

Programs which compile regular expressions from untrusted sources may be vulnerable to memory exhaustion or denial of service. 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. After fix, each regexp being parsed is limited to a 256 MB memory footprint. Regular expressions whose representation would use more space than that are rejected. Normal use of regular expressions is unaffected.

Due to unsanitized NUL values, attackers may be able to maliciously set environment variables on Windows. In syscall.StartProcess and os/exec.Cmd, invalid environment variable values containing NUL values are not properly checked for. A malicious environment variable value can exploit this behavior to set a value for a different environment variable. For example, the environment variable string "A=B\x00C=D" sets the variables "A=B" and "C=D".

An attacker can cause excessive memory growth in a Go server accepting HTTP/2 requests. HTTP/2 server connections contain a cache of HTTP header keys sent by the client. While the total number of entries in this cache is capped, an attacker sending very large keys can cause the server to allocate approximately 64 MiB per open connection.

Описание

On Windows, restricted files can be accessed via os.DirFS and http.Dir. The os.DirFS function and http.Dir type provide access to a tree of files rooted at a given directory. These functions permit access to Windows device files under that root. For example, os.DirFS("C:/tmp").Open("COM1") opens the COM1 device. Both os.DirFS and http.Dir only provide read-only filesystem access. In addition, on Windows, an os.DirFS for the directory (the root of the current drive) can permit a maliciously crafted path to escape from the drive and access any path on the system. With fix applied, the behavior of os.DirFS("") has changed. Previously, an empty root was treated equivalently to "/", so os.DirFS("").Open("tmp") would open the path "/tmp". This now returns an error.

A maliciously crafted HTTP/2 stream could cause excessive CPU consumption in the HPACK decoder, sufficient to cause a denial of service from a small number of small requests.

Large handshake records may cause panics in crypto/tls. Both clients and servers may send large TLS handshake records which cause servers and clients, respectively, to panic when attempting to construct responses. This affects all TLS 1.3 clients, TLS 1.2 clients which explicitly enable session resumption (by setting Config.ClientSessionCache to a non-nil value), and TLS 1.3 servers which request client certificates (by setting Config.ClientAuth >= RequestClientCert).

A denial of service is possible from excessive resource consumption in net/http and mime/multipart. Multipart form parsing with mime/multipart.Reader.ReadForm can consume largely unlimited amounts of memory and disk files. This also affects form parsing in the net/http package with the Request methods FormFile, FormValue, ParseMultipartForm, and PostFormValue. ReadForm takes a maxMemory parameter, and is documented as storing "up to maxMemory bytes +10MB (reserved for non-file parts) in memory". File parts which cannot be stored in memory are stored on disk in temporary files. The unconfigurable 10MB reserved for non-file parts is excessively large and can potentially open a denial of service vector on its own. However, ReadForm did not properly account for all memory consumed by a parsed form, such as map entry overhead, part names, and MIME headers, permitting a maliciously crafted form to consume well over 10MB. In addition, ReadForm contained no limit on the number of disk files created, permitting a relatively small request body to create a large number of disk temporary files. With fix, ReadForm now properly accounts for various forms of memory overhead, and should now stay within its documented limit of 10MB + maxMemory bytes of memory consumption. Users should still be aware that this limit is high and may still be hazardous. In addition, ReadForm now creates at most one on-disk temporary file, combining multiple form parts into a single temporary file. The mime/multipart.File interface type's documentation states, "If stored on disk, the File's underlying concrete type will be an *os.File.". This is no longer the case when a form contains more than one file part, due to this coalescing of parts into a single file. The previous behavior of using distinct files for each form part may be reenabled with the environment variable GODEBUG=multipartfiles=distinct. Users should be aware that multipart.ReadForm and the http.Request methods that call it do not limit the amount of disk consumed by temporary files. Callers can limit the size of form data with http.MaxBytesReader.
