Debian LTS Advisory DLA-2527-1 [email protected]
https://www.debian.org/lts/security/ Brian May
January 18, 2021 https://wiki.debian.org/LTS
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
