Summary
Moderate: go-toolset:rhel8 security, bug fix, and enhancement update
Details
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)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Additional Changes:
For detailed information on changes in this release, see the AlmaLinux Release Notes linked from the References section.

EPSS
Summary
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.
Severity ?
No CVSS data available.
