From https://bugzilla.redhat.com/1804533 : Upcoming security fix for the golang.org/x/crypto/ssh package in the golang.org/x/crypto module. Reference: https://groups.google.com/forum/#!topic/kubernetes-security-discuss/s15RxeNdBLc @maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.

Patch: https://github.com/golang/crypto/commit/bac4c82f69751a6dd76e702d54b3ceb88adab236 It looks like this is actually dev-go/go-crypto. @maintainer(s): ok to apply patch or create a new ebuild? thanks!

Another vulnerability. 2) CVE-2020-7919 Description: "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." URL: https://groups.google.com/forum/#!topic/golang-announce/Hsw4mHYc470 (see also bug 712924). May be easier to just bump the ebuild at this point.
We need to check which versions contain https://github.com/golang/crypto/commit/bac4c82f69751a6dd76e702d54b3ceb88adab236.
Vulnerability is in dev-go/go-crypto! Package has no stable ebuild. @ maintainer(s): Please bump and drop =dev-go/go-crypto-0_pre20180816 aferwards!
The dev-go/go-crypto package is deprecated and the only non-masked and non-deprecated consumer package is dev-embedded/arduino-builder-1.4.1 (dev-embedded/arduino-builder1.4.1-r1 is fixed). The dependency chain is: dev-embedded/arduino-builder-1.4.1 -> dev-go/go-net (deprecated) -> dev-go/go-crypto (deprecated) @embedded: please remove dev-embedded/arduino-builder-1.4.1.
CVE-2019-11841 (https://nvd.nist.gov/vuln/detail/CVE-2019-11841): A message-forgery issue was discovered in crypto/openpgp/clearsign/clearsign.go in supplementary Go cryptography libraries 2019-03-25. According to the OpenPGP Message Format specification in RFC 4880 chapter 7, a cleartext signed message can contain one or more optional "Hash" Armor Headers. The "Hash" Armor Header specifies the message digest algorithm(s) used for the signature. However, the Go clearsign package ignores the value of this header, which allows an attacker to spoof it. Consequently, an attacker can lead a victim to believe the signature was generated using a different message digest algorithm than what was actually used. Moreover, since the library skips Armor Header parsing in general, an attacker can not only embed arbitrary Armor Headers, but also prepend arbitrary text to cleartext messages without invalidating the signatures.
Arches and Maintainer(s), Thank you for your work.
