CVE-2019-11840 An issue was discovered in supplementary Go cryptography libraries, aka golang-googlecode-go-crypto. If more than 256 GiB of keystream is generated, or if the counter otherwise grows greater than 32 bits, the amd64 implementation will first generate incorrect output, and then cycle back to previously generated keystream. Repeated keystream bytes can lead to loss of confidentiality in encryption applications, or to predictability in CSPRNG applications. CVE-2019-11841 A message-forgery issue was discovered in crypto/openpgp/clearsign/clearsign.go in supplementary Go cryptography libraries. The "Hash" Armor Header specifies the message digest algorithm(s) used for the signature. 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. CVE-2020-9283 golang.org/x/crypto allows a panic during signature verification in the golang.org/x/crypto/ssh package. A client can attack an SSH server that accepts public keys. Also, a server can attack any SSH client. Thefollowing Go packages have been rebuilt in order to fix the aforementioned issues. rclone: 1.45-3+deb10u1 obfs4proxy: 0.0.7-4+deb10u1 gobuster: 2.0.1-1+deb10u1 restic: 0.9.4+ds-2+deb10u1 gopass: 1.2.0-2+deb10u1 aptly: 1.3.0+ds1-2.2~deb10u2: dnscrypt-proxy: 2.0.19+ds1-2+deb10u1 g10k: 0.5.7-1+deb10u1 hub: 2.7.0~ds1-1+deb10u1 acmetool: 0.0.62-3+deb10u1 syncthing: 1.0.0~ds1-1+deb10u1 packer: 1.3.4+dfsg-4+deb10u1 etcd: 3.2.26+dfsg-3+deb10u1 notary: 0.6.1~ds1-3+deb10u1 For Debian 10 buster, these problems have been fixed in version 1:0.0~git20181203.505ab14-1+deb10u1. We recommend that you upgrade your golang-go.crypto packages.
