Debian Bug     : 989492 991961

Several vulnerabilities were discovered in the Go programming
language. An attacker could trigger a denial-of-service (DoS) and
information leak.


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


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


    Follow-up fix to CVE-2021-33196


    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.


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


    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.

For Debian 9 stretch, these problems have been fixed in version

We recommend that you upgrade your golang-1.8 packages.
