Package : snapd Version : 2.21-2+deb9u1 CVE ID : CVE-2019-11840 golang-go.crypto was recently updated with a fix for CVE-2019-11840. This in turn requires all packages that use the affected code to be recompiled in order to pick up the security fix. 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. For Debian 9 stretch, this problem has been fixed in version 2.21-2+deb9u1. We recommend that you upgrade your snapd packages. For the detailed security status of snapd please refer to its security tracker page at: https://security-tracker.debian.org/tracker/snapd Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS -----BEGIN PGP SIGNATURE----- iQIzBAEBCAAdFiEEKpwfR8DOwu5vyB4TKpJZkldkSvoFAmAEqecACgkQKpJZkldk SvoQLg//c/lgWl8t2By4anfuAS3NbIO0pHvEpvZ9bw1CuffMFUG+DAIdjUYR9LHT T/dfrZccoJh+CKo7dU/vCKJDZaBdIdDzX420oQQQ+4MxUEpkq1iFlyy3UblV4mL6 79wpQY6QCEr/ytycl82NJSXUNo38EBH97lf3W9XeBm4cPscYbBBjbIpXD6748jNo e80KHNrVhQEbEUjEWbekgEgwSWGBnjIoImBQaZWvT3xiR6HkuTAnoF7FS6LbGUqe /IQa4FlyLzXU6JSWDkKgzgXVTdfrlVwH3cdElqIK2Rv/IA0Lm9gokzFQ+AZ4j7VH TDX2Sn+q6ls8MTohDDxi+byTVwBP0P9SnKyRKxSkcf9n5SzUyt16AtJdGcwn+bj4 0l+2nRZOjqMzXPCPQTFSfrdRONXyACeDftnScv+a1eFknQKvurskkLfeoqFG8mvN pgDQ00RQrT9YzD0L00OKMpL7c02f/cAH+3kiIlhXqpGk8m9xusZeFE/et7zihOCp aO7sS+hrl6Sve9JVVLWwjlttNTFgyK3S7w7yf+AJ7lhAzRYKTsNyDojYk3Oafuve 2YM8+6PxFN7QUQh6nDTe5Yc59bjifPXOJs0X8xEyPIDJs6i7KtvnsH+et82vHP1e Bvg/7eEKavqLKjp7UxSKTW2Kl7EqnpYma4bmLu9fe4g8ZQoY3Rs= =Dw9o -----END PGP SIGNATURE-----
