Careful management of the journal read pointer is sufficient to ensure

Unit test the journald logger without requiring a running journald by

We have just released Go versions 1.18.4 and 1.17.12, minor point releases. These
minor releases include 9 security fixes following the security policy:
- net/http: improper sanitization of Transfer-Encoding header
The HTTP/1 client accepted some invalid Transfer-Encoding headers as indicating
a "chunked" encoding. This could potentially allow for request smuggling, but
only if combined with an intermediate server that also improperly failed to
reject the header as invalid.
This is CVE-2022-1705 and https://go.dev/issue/53188.
- When `httputil.ReverseProxy.ServeHTTP` was called with a `Request.Header` map
containing a nil value for the X-Forwarded-For header, ReverseProxy would set
the client IP as the value of the X-Forwarded-For header, contrary to its
documentation. In the more usual case where a Director function set the
X-Forwarded-For header value to nil, ReverseProxy would leave the header
unmodified as expected.
This is https://go.dev/issue/53423 and CVE-2022-32148.
Thanks to Christian Mehlmauer for reporting this issue.
- compress/gzip: stack exhaustion in Reader.Read
Calling Reader.Read on an archive containing a large number of concatenated
0-length compressed files can cause a panic due to stack exhaustion.
This is CVE-2022-30631 and Go issue https://go.dev/issue/53168.
- encoding/xml: stack exhaustion in Unmarshal
Calling Unmarshal on a XML document into a Go struct which has a nested field
that uses the any field tag can cause a panic due to stack exhaustion.
This is CVE-2022-30633 and Go issue https://go.dev/issue/53611.
- encoding/xml: stack exhaustion in Decoder.Skip
Calling Decoder.Skip when parsing a deeply nested XML document can cause a
panic due to stack exhaustion. The Go Security team discovered this issue, and
it was independently reported by Juho Nurminen of Mattermost.
This is CVE-2022-28131 and Go issue https://go.dev/issue/53614.
- encoding/gob: stack exhaustion in Decoder.Decode
Calling Decoder.Decode on a message which contains deeply nested structures
can cause a panic due to stack exhaustion.
This is CVE-2022-30635 and Go issue https://go.dev/issue/53615.

cause a panic due to stack exhaustion.
This is CVE-2022-30630 and Go issue https://go.dev/issue/53415.

Hello gophers,
We have just released Go versions 1.18.3 and 1.17.11, minor point releases.
These minor releases include 4 security fixes following the security policy:
- crypto/rand: rand.Read hangs with extremely large buffers
On Windows, rand.Read will hang indefinitely if passed a buffer larger than
1 << 32 - 1 bytes.
Thanks to Davis Goodin and Quim Muntal, working at Microsoft on the Go toolset,
for reporting this issue.
This is [CVE-2022-30634][CVE-2022-30634] and Go issue https://go.dev/issue/52561.
- crypto/tls: session tickets lack random ticket_age_add
Session tickets generated by crypto/tls did not contain a randomly generated
ticket_age_add. This allows an attacker that can observe TLS handshakes to
correlate successive connections by comparing ticket ages during session
resumption.
Thanks to GitHub user nervuri for reporting this.
This is [CVE-2022-30629][CVE-2022-30629] and Go issue https://go.dev/issue/52814.
- `os/exec`: empty `Cmd.Path` can result in running unintended binary on Windows
If, on Windows, `Cmd.Run`, `cmd.Start`, `cmd.Output`, or `cmd.CombinedOutput`
are executed when Cmd.Path is unset and, in the working directory, there are
binaries named either "..com" or "..exe", they will be executed.

Similar to the (now removed) `apparmor` build tag, this build-time toggle existed for users who needed to build without the `libseccomp` library. That's no longer necessary, and given the importance of seccomp to the overall default security profile of Docker containers, it makes sense that any binary built for Linux should support (and use by default) seccomp if the underlying host does.

A copy of Go's archive/tar packge was vendored with a patch applied to
mitigate CVE-2019-14271. Vendoring standard library packages is not
supported by Go in module-aware mode, which is getting in the way of
maintenance. A different approach to mitigate the vulnerability is
needed which does not involve vendoring parts of the standard library.
glibc implements name service lookups such as users, groups and DNS
using a scheme known as Name Service Switch. The services are
implemented as modules, shared libraries which glibc dynamically links
into the process the first time a function requiring the module is
called. This is the crux of the vulnerability: if a process linked
against glibc chroots, then calls one of the functions implemented with
NSS for the first time, glibc may load NSS modules out of the chrooted
filesystem.
The API underlying the `docker cp` command is implemented by forking a
new process which chroots into the container's rootfs and writes a tar
stream of files from the container over standard output. It utilizes the
Go standard library's archive/tar package to write the tar stream. It
makes use of the tar.FileInfoHeader function to construct a tar.Header
value from an fs.FileInfo value. In modern versions of Go on *nix
platforms, FileInfoHeader will attempt to resolve the file's UID and GID
to their respective user and group names by calling the os/user
functions LookupId and LookupGroupId. The cgo implementation of os/user
on *nix performs lookups by calling the corresponding libc functions. So
when linked against glibc, calls to tar.FileInfoHeader after the
process has chrooted into the container's rootfs can have the side
effect of loading NSS modules from the container! Without any
mitigations, a malicious container image author can trivially get
arbitrary code execution by leveraging this vulnerability and escape the
chroot (which is not a sandbox) into the host.
Mitigate the vulnerability without patching or forking archive/tar by
hiding the OS-dependent file info from tar.FileInfoHeader which it needs
to perform the lookups. Without that information available it falls back
to populating the tar.Header with only the information obtainable
directly from the FileInfo value without making any calls into os/user.
