Debian Bug     : 989492 991961

Multiple vulnerabilities were discovered in the Go programming
language. An attacker could trigger a denial-of-service (DoS), invalid
cryptographic computation, information leak, or arbitrary code
execution on the developer's computer in specific situations.

CVE-2020-28367

    Code injection in the go command with cgo allows arbitrary code
    execution at build time via malicious gcc flags specified via a
    #cgo directive.

CVE-2021-33196

    In archive/zip, a crafted file count (in an archive's header) can
    cause a NewReader or OpenReader panic.

CVE-2021-36221

    Go has a race condition that can lead to a net/http/httputil
    ReverseProxy panic upon an ErrAbortHandler abort.

CVE-2021-38297

    Go has a Buffer Overflow via large arguments in a function
    invocation from a WASM module, when GOARCH=wasm GOOS=js is used.

CVE-2021-39293

    This issue exists because of an incomplete fix for CVE-2021-33196.

CVE-2021-41771

    ImportedSymbols in debug/macho (for Open or OpenFat) Accesses a
    Memory Location After the End of a Buffer, aka an out-of-bounds
    slice situation.

CVE-2021-44716

    net/http allows uncontrolled memory consumption in the header
    canonicalization cache via HTTP/2 requests.

CVE-2021-44717

    Go on UNIX allows write operations to an unintended file or
    unintended network connection as a consequence of erroneous
    closing of file descriptor 0 after file-descriptor exhaustion.

CVE-2022-23806

    Curve.IsOnCurve in crypto/elliptic can incorrectly return true in
    situations with a big.Int value that is not a valid field element.

CVE-2022-24921

    regexp.Compile allows stack exhaustion via a deeply nested
    expression.

For Debian 10 buster, these problems have been fixed in version
1.11.6-1+deb10u6.

We recommend that you upgrade your golang-1.11 packages.
