Beschreibung:	Summary: The remote host is missing an update for the 'golang' package(s) announced via the MGASA-2021-0369 advisory. Vulnerability Insight: encoding/xml in Go before 1.15.9 and 1.16.x before 1.16.1 has an infinite loop if a custom TokenReader (for xml.NewTokenDecoder) returns EOF in the middle of an element. This can occur in the Decode, DecodeElement, or Skip method (CVE-2021-27918). net/http in Go before 1.15.12 and 1.16.x before 1.16.4 allows remote attackers to cause a denial of service (panic) via a large header to ReadRequest or ReadResponse. Server, Transport, and Client can each be affected in some configurations (CVE-2021-31525). A security issue has been found in Go before version 1.16.5. The LookupCNAME, LookupSRV, LookupMX, LookupNS, and LookupAddr functions in net, and their respective methods on the Resolver type may return arbitrary values retrieved from DNS which do not follow the established RFC 1035 rules for domain names. If these names are used without further sanitization, for instance unsafely included in HTML, they may allow for injection of unexpected content. Note that LookupTXT may still return arbitrary values that could require sanitization before further use (CVE-2021-33195). A security issue has been found in Go. Due to a pre-allocation optimization in zip.NewReader, a malformed archive which indicates it has a significant number of files can cause either a panic or memory exhaustion (CVE-2021-33196). ReverseProxy fails to delete the Connection headers (as well as other legacy hop-by-hop headers, which however per RFC 7230 need to also be specified in Connection) if there are multiple ones and the first is empty, due to an incorrect Get(h) == '' check. This can lead to a security issue if the proxy is adding an important header, like X-Forwarded-For, and is sitting in front of another proxy which can be instructed by an attacker to drop that header as a hop-by-hop header (CVE-2021-33197). A security issue has been found in Go before version 1.16.5. The SetString and UnmarshalText methods of math/big.Rat may cause a panic or an unrecoverable fatal error if passed inputs with very large exponents (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). Affected Software/OS: 'golang' package(s) on Mageia 8. Solution: Please install the updated package(s). CVSS Score: 7.5 CVSS Vector: AV:N/AC:L/Au:N/C:P/I:P/A:P
