Security Fix(es):

* golang: net/http/httputil: ReverseProxy forwards connection headers if first one is empty (CVE-2021-33197)
* golang: math/big.Rat: may cause a panic or an unrecoverable fatal error if passed inputs with very large exponents (CVE-2021-33198)
* golang: crypto/tls: certificate of wrong type is causing TLS client to panic (CVE-2021-34558)
* golang: net/http/httputil: panic due to racy read of persistConn after handler panic (CVE-2021-36221)

A flaw was found in golang. Extraneous zero characters at the beginning of an IP address octet are not properly considered which could allow an attacker to bypass IP-based access controls. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
7.3 (High)
Vendor Fix
For details on how to apply this update, which includes the changes described in this advisory, refer to:
https://access.redhat.com/articles/11258
https://access.redhat.com/errata/RHSA-2022:0947
Workaround
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
A flaw was found in Go. The LookupCNAME, LookupSRV, LookupMX, LookupNS, and LookupAddr functions in the net package and methods on the Resolver type, may return arbitrary values retrieved from DNS, allowing injection of unexpected contents. The highest threat from this vulnerability is to integrity.
7.5 (High)
Vendor Fix
For details on how to apply this update, which includes the changes described in this advisory, refer to:
https://access.redhat.com/articles/11258
https://access.redhat.com/errata/RHSA-2022:0947
A flaw was found in Go, acting as an unintended proxy or intermediary, where ReverseProxy forwards connection headers if the first one was empty. This flaw allows an attacker to drop arbitrary headers. The highest threat from this vulnerability is to integrity.
5.3 (Medium)
Vendor Fix
For details on how to apply this update, which includes the changes described in this advisory, refer to:
https://access.redhat.com/articles/11258
https://access.redhat.com/errata/RHSA-2022:0947
A flaw was found in Go, where it attempts to allocate excessive memory. This issue may cause panic or unrecoverable fatal error if passed inputs with very large exponents. The highest threat from this vulnerability is to system availability.
7.5 (High)
Vendor Fix
For details on how to apply this update, which includes the changes described in this advisory, refer to:
https://access.redhat.com/articles/11258
https://access.redhat.com/errata/RHSA-2022:0947
A flaw was found in golang. A panic can be triggered by an attacker in a privileged network position without access to the server certificate's private key, as long as a trusted ECDSA or Ed25519 certificate for the server exists (or can be issued), or the client is configured with Config.InsecureSkipVerify. Clients that disable all TLS_RSA cipher suites (that is, TLS 1.0–1.2 cipher suites without ECDHE), as well as TLS 1.3-only clients, are unaffected.
6.5 (Medium)
Vendor Fix
For details on how to apply this update, which includes the changes described in this advisory, refer to:
https://access.redhat.com/articles/11258
https://access.redhat.com/errata/RHSA-2022:0947
Workaround
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
A race condition flaw was found in Go. The incoming requests body weren't closed after the handler panic and as a consequence this could lead to ReverseProxy crash. The highest threat from this vulnerability is to Availability.
5.9 (Medium)
Vendor Fix
For details on how to apply this update, which includes the changes described in this advisory, refer to:
https://access.redhat.com/articles/11258
https://access.redhat.com/errata/RHSA-2022:0947
Workaround
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
There's an uncontrolled resource consumption flaw in golang's net/http library in the canonicalHeader() function. An attacker who submits specially crafted requests to applications linked with net/http's http2 functionality could cause excessive resource consumption that could lead to a denial of service or otherwise impact to system performance and resources.
7.5 (High)
Vendor Fix
For details on how to apply this update, which includes the changes described in this advisory, refer to:
https://access.redhat.com/articles/11258
https://access.redhat.com/errata/RHSA-2022:0947
Workaround
This flaw can be mitigated by disabling HTTP/2. Setting the GODEBUG=http2server=0 environment variable before calling Serve will disable HTTP/2 unless it was manually configured through the golang.org/x/net/http2 package.
There's a flaw in golang's syscall.ForkExec() interface. An attacker who manages to first cause a file descriptor exhaustion for the process, then cause syscall.ForkExec() to be called repeatedly, could compromise data integrity and/or confidentiality in a somewhat uncontrolled way in programs linked with and using syscall.ForkExec().
4.8 (Medium)
Vendor Fix
For details on how to apply this update, which includes the changes described in this advisory, refer to:
https://access.redhat.com/articles/11258
https://access.redhat.com/errata/RHSA-2022:0947
Workaround
This bug can be mitigated by raising the per-process file descriptor limit.
