A flaw was found in the amd64 implementation of the golang.org/x/crypto/salsa20 and golang.org/x/crypto/salsa20/salsa packages. 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."}],"affected":[{"vendor":"n/a","product":"n/a","versions":[{"version":"n/a","status":"affected"}]}],"references":[{"url":"https://groups.google.com/forum/#%21msg/golang-announce/tjyNcJxb2vQ/n0NRBziSCAAJ"},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=1691529"},{"url":"https://go.googlesource.com/crypto/+/b7391e95e576cacdcdd422573063bc057239113d"},{"url":"https://github.com/golang/go/issues/30965"},{"name":"[debian-lts-announce] 20190630 [SECURITY] [DLA 1840-1] golang-go.crypto security update","tags":["mailing-list"],"url":"https://lists.debian.org/debian-lts-announce/2019/06/msg00029.html"},{"name":"[debian-lts-announce] 20201007 [SECURITY] [DLA 2402-1] golang-go.crypto security update","tags":["mailing-list"],"url":"https://lists.debian.org/debian-lts-announce/2020/10/msg00014.html"},{"name":"[debian-lts-announce] 20201109 [SECURITY] [DLA 2442-1] obfs4proxy security update","tags":["mailing-list"],"url":"https://lists.debian.org/debian-lts-announce/2020/11/msg00016.html"},{"name":"[debian-lts-announce] 20201118 [SECURITY] [DLA 2454-1] rclone security update","tags":["mailing-list"],"url":"https://lists.debian.org/debian-lts-announce/2020/11/msg00030.html"},{"name":"[debian-lts-announce] 20210117 [SECURITY] [DLA 2527-1] snapd security update","tags":["mailing-list"],"url":"https://lists.debian.org/debian-lts-announce/2021/01/msg00015.html"},{"name":"[debian-lts-announce] 20230616 [SECURITY] [DLA 3455-1] golang-go.crypto security update","tags":["mailing-list"],"url":"https://lists.debian.org/debian-lts-announce/2023/06/msg00017.html"},{"url":"https://pkg.go.dev/vuln/GO-2022-0209"}],"problemTypes":[{"descriptions":[{"type":"text","lang":"en","description":"n/a"}]}]},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-04T23:03:32.886Z"},"title":"CVE Program Container","references":[{"url":"https://groups.google.com/forum/#%21msg/golang-announce/tjyNcJxb2vQ/n0NRBziSCAAJ","tags":["x_transferred"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=1691529","tags":["x_transferred"]},{"url":"https://go.googlesource.com/crypto/+/b7391e95e576cacdcdd422573063bc057239113d","tags":["x_transferred"]},{"url":"https://github.com/golang/go/issues/30965","tags":["x_transferred"]},{"name":"[debian-lts-announce] 20190630 [SECURITY] [DLA 1840-1] golang-go.crypto security update","tags":["mailing-list","x_transferred"],"url":"https://lists.debian.org/debian-lts-announce/2019/06/msg00029.html"},{"name":"[debian-lts-announce] 20201007 [SECURITY] [DLA 2402-1] golang-go.crypto security update","tags":["mailing-list","x_transferred"],"url":"https://lists.debian.org/debian-lts-announce/2020/10/msg00014.html"},{"name":"[debian-lts-announce] 20201109 [SECURITY] [DLA 2442-1] obfs4proxy security update","tags":["mailing-list","x_transferred"],"url":"https://lists.debian.org/debian-lts-announce/2020/11/msg00016.html"},{"name":"[debian-lts-announce] 20201118 [SECURITY] [DLA 2454-1] rclone security update","tags":["mailing-list","x_transferred"],"url":"https://lists.debian.org/debian-lts-announce/2020/11/msg00030.html"},{"name":"[debian-lts-announce] 20210117 [SECURITY] [DLA 2527-1] snapd security update","tags":["mailing-list","x_transferred"],"url":"https://lists.debian.org/debian-lts-announce/2021/01/msg00015.html"},{"name":"[debian-lts-announce] 20230616 [SECURITY] [DLA 3455-1] golang-go.crypto security update","tags":["mailing-list","x_transferred"],"url":"https://lists.debian.org/debian-lts-announce/2023/06/msg00017.html"},{"url":"https://pkg.go.dev/vuln/GO-2022-0209","tags":["x_transferred"]}]}]},"dataVersion":"5.1"}
