From the announcement e-mail:
[security] Go 1.17.3 and Go 1.16.10 are released
We have just released Go versions 1.17.3 and 1.16.10, minor point releases.
These minor releases include two security fixes following the security policy:
- archive/zip: don't panic on (*Reader).Open
Reader.Open (the API implementing io/fs.FS introduced in Go 1.16) can be made
to panic by an attacker providing either a crafted ZIP archive containing
completely invalid names or an empty filename argument.
Thank you to Colin Arnott, SiteHost and Noah Santschi-Cooney, Sourcegraph Code
Intelligence Team for reporting this issue. This is CVE-2021-41772 and Go issue
golang.org/issue/48085.
- debug/macho: invalid dynamic symbol table command can cause panic
Malformed binaries parsed using Open or OpenFat can cause a panic when calling
ImportedSymbols, due to an out-of-bounds slice operation.
Thanks to Burak Çarıkçı - Yunus Yıldırım (CT-Zer0 Crypttech) for reporting this
issue. This is CVE-2021-41771 and Go issue golang.org/issue/48990.

go1.13.7 (released 2020/01/28) includes two security fixes. One mitigates
the CVE-2020-0601 certificate verification bypass on Windows. The other affects
only 32-bit architectures.
https://github.com/golang/go/issues?q=milestone%3AGo1.13.7+label%3ACherryPickApproved
- X.509 certificate validation bypass on Windows 10
A Windows vulnerability allows attackers to spoof valid certificate chains when
the system root store is in use. These releases include a mitigation for Go
applications, but it’s strongly recommended that affected users install the
Windows security update to protect their system.
This issue is CVE-2020-0601 and Go issue golang.org/issue/36834.
- Panic in crypto/x509 certificate parsing and golang.org/x/crypto/cryptobyte
On 32-bit architectures, a malformed input to crypto/x509 or the ASN.1 parsing
functions of golang.org/x/crypto/cryptobyte can lead to a panic.
The malformed certificate can be delivered via a crypto/tls connection to a
client, or to a server that accepts client certificates. net/http clients can
be made to crash by an HTTPS server, while net/http servers that accept client
certificates will recover the panic and are unaffected.
Thanks to Project Wycheproof for providing the test cases that led to the
discovery of this issue. The issue is CVE-2020-7919 and Go issue golang.org/issue/36837.
This is also fixed in version v0.0.0-20200124225646-8b5121be2f68 of golang.org/x/crypto/cryptobyte.

Hi gophers,
We have just released Go 1.13.1 and Go 1.12.10 to address a recently reported security issue. We recommend that all affected users update to one of these releases (if you're not sure which, choose Go 1.13.1).
net/http (through net/textproto) used to accept and normalize invalid HTTP/1.1 headers with a space before the colon, in violation of RFC 7230. If a Go server is used behind an uncommon reverse proxy that accepts and forwards but doesn't normalize such invalid headers, the reverse proxy and the server can interpret the headers differently. This can lead to filter bypasses or request smuggling, the latter if requests from separate clients are multiplexed onto the same upstream connection by the proxy. Such invalid headers are now rejected by Go servers, and passed without normalization to Go client applications.
The issue is CVE-2019-16276 and Go issue golang.org/issue/34540.
Thanks to Andrew Stucki, Adam Scarr (99designs.com), and Jan Masarik (masarik.sh) for discovering and reporting this issue.
Downloads are available at https://golang.org/dl for all supported platforms.
Alla prossima,
Filippo on behalf of the Go team
```
From the patch: 6e6f4aaf70
```
net/textproto: don't normalize headers with spaces before the colon
RFC 7230 is clear about headers with a space before the colon, like
X-Answer : 42
being invalid, but we've been accepting and normalizing them for compatibility
purposes since CL 5690059 in 2012.
On the client side, this is harmless and indeed most browsers behave the same
to this day. On the server side, this becomes a security issue when the
behavior doesn't match that of a reverse proxy sitting in front of the server.
For example, if a WAF accepts them without normalizing them, it might be
possible to bypass its filters, because the Go server would interpret the
header differently. Worse, if the reverse proxy coalesces requests onto a
single HTTP/1.1 connection to a Go server, the understanding of the request
boundaries can get out of sync between them, allowing an attacker to tack an
arbitrary method and path onto a request by other clients, including
authentication headers unknown to the attacker.
This was recently presented at multiple security conferences:
https://portswigger.net/blog/http-desync-attacks-request-smuggling-reborn
net/http servers already reject header keys with invalid characters.
Simply stop normalizing extra spaces in net/textproto, let it return them
unchanged like it does for other invalid headers, and let net/http enforce
RFC 7230, which is HTTP specific. This loses us normalization on the client
side, but there's no right answer on the client side anyway, and hiding the
issue sounds worse than letting the application decide.

go1.12.8 (released 2019/08/13) includes security fixes to the net/http and net/url packages.
See the Go 1.12.8 milestone on our issue tracker for details:
https://github.com/golang/go/issues?q=milestone%3AGo1.12.8
- net/http: Denial of Service vulnerabilities in the HTTP/2 implementation
net/http and golang.org/x/net/http2 servers that accept direct connections from untrusted
clients could be remotely made to allocate an unlimited amount of memory, until the program
crashes. Servers will now close connections if the send queue accumulates too many control
messages.
The issues are CVE-2019-9512 and CVE-2019-9514, and Go issue golang.org/issue/33606.
Thanks to Jonathan Looney from Netflix for discovering and reporting these issues.
This is also fixed in version v0.0.0-20190813141303-74dc4d7220e7 of golang.org/x/net/http2.
net/url: parsing validation issue
- url.Parse would accept URLs with malformed hosts, such that the Host field could have arbitrary
suffixes that would appear in neither Hostname() nor Port(), allowing authorization bypasses
in certain applications. Note that URLs with invalid, not numeric ports will now return an error
from url.Parse.
The issue is CVE-2019-14809 and Go issue golang.org/issue/29098.

The Golang base images switch to buster, which causes some breakage
in networking and packages that are no longer available; (`btrfs-tools`
is now an empty package, and `libprotobuf-c0-dev` is gone).
Some of out tests also start faiilng on stretch, and will have to be
investigated further;
