ALSA-2021:4156 — Moderate: go-toolset:rhel8 security, bug fix, and enhancement update

Affected: AlmaLinux:8: delve

Go Toolset provides the Go programming language tools and libraries. Go is alternatively known as golang.

The following packages have been upgraded to a later upstream version: golang (1.16.7). (BZ#1938071)

Security Fix(es):

* golang: net: lookup functions may return invalid host names (CVE-2021-33195)

* 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: net/http/httputil: panic due to racy read of persistConn after handler panic (CVE-2021-36221)

OESA-2021-1402 — golang security update

Affected: openEuler:20.03-LTS-SP1: golang, openEuler:20.03-LTS-SP2: golang

The go programming language Security Fix(es): Go before 1.15.13 and 1.16.x before 1.16.5 has functions for DNS lookups that do not validate replies from DNS servers, and thus a return value may contain an unsafe injection (e.g., XSS) that does not conform to the RFC1035 format.(CVE-2021-33195)

In archive/zip in Go before 1.15.13 and 1.16.x before 1.16.5, a crafted file count (in an archive s header) can cause a NewReader or OpenReader panic.(CVE-2021-33196)

In Go before 1.15.13 and 1.16.x before 1.16.5, some configurations of ReverseProxy (from net/http/httputil) result in a situation where an attacker is able to drop arbitrary headers.(CVE-2021-33197)

In Go before 1.15.13 and 1.16.x before 1.16.5, there can be a panic for a large exponent to the math/big.Rat SetString or UnmarshalText method.(CVE-2021-33198)

The crypto/tls package of Go through 1.16.5 does not properly assert that the type of public key in an X.509 certificate matches the expected type when doing a RSA based key exchange, allowing a malicious TLS server to cause a TLS client to panic.(CVE-2021-34558)

Go before 1.17 does not properly consider extraneous zero characters at the beginning of an IP address octet, which (in some situations) allows attackers to bypass access control that is based on IP addresses, because of unexpected octal interpretation. This affects net.ParseIP and net.ParseCIDR.(CVE-2021-29923)

Go before 1.16.9 and 1.17.x before 1.17.2 has a Buffer Overflow via large arguments in a…
