This is the first release of the 1.3.z release branch of runc. It
contains a few minor fixes for issues found in 1.3.0-rc.2.
This is the first release of runc that will follow our new release and
support policy (see RELEASES.md for more details). This means that, as
of this release:
As of this release, the runc 1.2.z release branch will now only
receive security and "significant" bugfixes.
Users are encouraged to plan migrating to runc 1.3.0 as soon as
possible.
Due to its particular situation, runc 1.1.z is officially no longer
supported and will no longer receive any updates (not even for
critical security issues). Users are urged (in the strongest possible
terms) to upgrade to a supported version of runc.
Barring any future changes to our release policy, users should expect
a runc 1.4.0 release in late October 2025.

This is the fifth patch release in the 1.2.z series of runc. It
primarily fixes an issue caused by an upstream systemd bug.
There was a regression in systemd v230 which made the way we define device
rule restrictions require a systemctl daemon-reload for our transient
units. This caused issues for workloads using NVIDIA GPUs. Workaround the
upstream regression by re-arranging how the unit properties are defined.
Dependency github.com/cyphar/filepath-securejoin is updated to v0.4.1,
to allow projects that vendor runc to bump it as well.
CI: fixed criu-dev compilation.
Dependency golang.org/x/net is updated to 0.33.0.

This is the fourth patch release of the 1.2.z release branch of runc. It
includes a fix for a regression introduced in 1.2.0 related to the
default device list.
- Re-add tun/tap devices to built-in allowed devices lists.
In runc 1.2.0 we removed these devices from the default allow-list
(which were added seemingly by accident early in Docker's history) as
a precaution in order to try to reduce the attack surface of device
inodes available to most containers. At the time we thought
that the vast majority of users using tun/tap would already be
specifying what devices they need (such as by using --device with
Docker/Podman) as opposed to doing the mknod manually, and thus
there would've been no user-visible change.
Unfortunately, it seems that this regressed a noticeable number of
users (and not all higher-level tools provide easy ways to specify
devices to allow) and so this change needed to be reverted. Users
that do not need these devices are recommended to explicitly disable
them by adding deny rules in their container configuration.

This is the third patch release of the 1.2.z release branch of runc. It
primarily fixes some minor regressions introduced in 1.2.0.
- Fixed a regression in use of securejoin.MkdirAll, where multiple
runc processes racing to create the same mountpoint in a shared rootfs
would result in spurious EEXIST errors. In particular, this regression
caused issues with BuildKit.
- Fixed a regression in eBPF support for pre-5.6 kernels after upgrading
Cilium's eBPF library version to 0.16 in runc.

runc v1.1.13 introduced an option to customize the version (as printed by the
`--version` flag) through a `VERSION` Make variable / environment variable
(see [1]).
This variable collided with the `VERSION` environment variable used by
containerd for the same purpose, which lead to `runc` binaries built
using the version of containerd;
runc --version
runc version 1.7.20

These minor releases include 1 security fixes following the security policy:
- http2: close connections when receiving too many headers
Maintaining HPACK state requires that we parse and process all HEADERS
and CONTINUATION frames on a connection. When a request's headers exceed
MaxHeaderBytes, we don't allocate memory to store the excess headers but
we do parse them. This permits an attacker to cause an HTTP/2 endpoint
to read arbitrary amounts of header data, all associated with a request
which is going to be rejected. These headers can include Huffman-encoded
data which is significantly more expensive for the receiver to decode
than for an attacker to send.
Set a limit on the amount of excess header frames we will process before
closing a connection.

[security] Go 1.21.5 and Go 1.20.12 are released
Hello gophers,
We have just released Go versions 1.21.5 and 1.20.12, minor point releases.
These minor releases include 3 security fixes following the security policy:
- net/http: limit chunked data overhead
A malicious HTTP sender can use chunk extensions to cause a receiver
reading from a request or response body to read many more bytes from
the network than are in the body.
A malicious HTTP client can further exploit this to cause a server to
automatically read a large amount of data (up to about 1GiB) when a
handler fails to read the entire body of a request.
Chunk extensions are a little-used HTTP feature which permit including
additional metadata in a request or response body sent using the chunked
encoding. The net/http chunked encoding reader discards this metadata.
A sender can exploit this by inserting a large metadata segment with
each byte transferred. The chunk reader now produces an error if the
ratio of real body to encoded bytes grows too small.
Thanks to Bartek Nowotarski for reporting this issue.
This is CVE-2023-39326 and Go issue https://go.dev/issue/64433.
- cmd/go: go get may unexpectedly fallback to insecure git
Using go get to fetch a module with the ".git" suffix may unexpectedly
fallback to the insecure "git://" protocol if the module is unavailable
via the secure "https://" and "git+ssh://" protocols, even if GOINSECURE
is not set for said module. This only affects users who are not using
the module proxy and are fetching modules directly (i.e. GOPROXY=off).
Thanks to David Leadbeater for reporting this issue.
This is CVE-2023-45285 and Go issue https://go.dev/issue/63845.
- path/filepath: retain trailing \ when cleaning paths like \\?\c:\
Go 1.20.11 and Go 1.21.4 inadvertently changed the definition of the
volume name in Windows paths starting with \\?\, resulting in
filepath.Clean(\\?\c:\) returning \\?\c: rather than \\?\c:\ (among
other effects). The previous behavior has been restored.

[security] Go 1.21.4 and Go 1.20.11 are released
Hello gophers,
We have just released Go versions 1.21.4 and 1.20.11, minor point releases.
These minor releases include 2 security fixes following the security policy:
- path/filepath: recognize `\??\` as a Root Local Device path prefix.
On Windows, a path beginning with `\??\` is a Root Local Device path equivalent
to a path beginning with `\\?\`. Paths with a `\??\` prefix may be used to
access arbitrary locations on the system. For example, the path `\??\c:\x`
is equivalent to the more common path c:\x.
The filepath package did not recognize paths with a `\??\` prefix as special.
Clean could convert a rooted path such as `\a\..\??\b` into
the root local device path `\??\b`. It will now convert this
path into `.\??\b`.
`IsAbs` did not report paths beginning with `\??\` as absolute.
It now does so.
VolumeName now reports the `\??\` prefix as a volume name.
`Join(`\`, `??`, `b`)` could convert a seemingly innocent
sequence of path elements into the root local device path
`\??\b`. It will now convert this to `\.\??\b`.
This is CVE-2023-45283 and https://go.dev/issue/63713.
- path/filepath: recognize device names with trailing spaces and superscripts
The `IsLocal` function did not correctly detect reserved names in some cases:
- reserved names followed by spaces, such as "COM1 ".
- "COM" or "LPT" followed by a superscript 1, 2, or 3.
`IsLocal` now correctly reports these names as non-local.
This is CVE-2023-45284 and https://go.dev/issue/63713.

This is the tenth (and most likely final) patch release in the 1.1.z

umask-related issue in tmpcopyup.
- Add support for `hugetlb.<pagesize>.rsvd` limiting and accounting.
Fixes the issue of postgres failing when hugepage limits are set.
- Fixed permissions of a newly created directories to not depend on the value
of umask in tmpcopyup feature implementation.
- libcontainer: cgroup v1 GetStats now ignores missing `kmem.limit_in_bytes`
(fixes the compatibility with Linux kernel 6.1+).
- Fix a semi-arbitrary cgroup write bug when given a malicious hugetlb
configuration. This issue is not a security issue because it requires a
malicious config.json, which is outside of our threat model.

[security] Go 1.21.3 and Go 1.20.10 are released
Hello gophers,
We have just released Go versions 1.21.3 and 1.20.10, minor point releases.
These minor releases include 1 security fixes following the security policy:
- net/http: rapid stream resets can cause excessive work
A malicious HTTP/2 client which rapidly creates requests and
immediately resets them can cause excessive server resource consumption.
While the total number of requests is bounded to the
http2.Server.MaxConcurrentStreams setting, resetting an in-progress
request allows the attacker to create a new request while the existing
one is still executing.
HTTP/2 servers now bound the number of simultaneously executing
handler goroutines to the stream concurrency limit. New requests
arriving when at the limit (which can only happen after the client
has reset an existing, in-flight request) will be queued until a
handler exits. If the request queue grows too large, the server
will terminate the connection.
This issue is also fixed in golang.org/x/net/http2 v0.17.0,
for users manually configuring HTTP/2.
The default stream concurrency limit is 250 streams (requests)
per HTTP/2 connection. This value may be adjusted using the
golang.org/x/net/http2 package; see the Server.MaxConcurrentStreams
setting and the ConfigureServer function.
This is CVE-2023-39325 and Go issue https://go.dev/issue/63417.
This is also tracked by CVE-2023-44487.
