This week

MEDIUM 5.9REMOTEUPGRADE

CVE-2018-18908 is a medium-severity flaw (CVSS 5.9) affecting sky go. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

The Sky Go Desktop application 1.0.19-1 through 1.0.23-1 for Windows performs several requests over cleartext HTTP. This makes the data submitted in these requests prone to Man in The Middle (MiTM) attacks, whereby an attacker would be able to obtain the data sent in these requests. Some of the requests contain potentially sensitive information that could be useful to an attacker, such as the victim's Sky username.

sky sky go UPGRADE

Affected: >= 1.0.19-1 and <= 1.0.23-1

Fixed in: newer than 1.0.23-1

Safe to downgrade to: a release before 1.0.19-1

1. Check installed version

apt-cache policy sky-go || rpm -q sky-go || sky-go --version

2. UPGRADE to newer than 1.0.23-1 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade sky-go

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade sky-go

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 1.0.19-1 (Debian / Ubuntu)

apt-cache madison sky-go sudo apt install sky-go=<VERSION_BEFORE_1.0.19-1> sudo apt-mark hold sky-go

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list sky-go sudo dnf downgrade sky-go-<VERSION_BEFORE_1.0.19-1> sudo dnf versionlock add sky-go

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
