This week

HIGH 7.5REMOTEUPGRADE

CVE-2022-39213 is a high-severity flaw (CVSS 7.5) affecting go-cvss. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

go-cvss is a Go module to manipulate Common Vulnerability Scoring System (CVSS). In affected versions when a full CVSS v2.0 vector string is parsed using `ParseVector`, an Out-of-Bounds Read is possible due to a lack of tests. The Go module will then panic. The problem is patched in tag `v0.4.0`, by the commit `d9d478ff0c13b8b09ace030db9262f3c2fe031f4`. Users are advised to upgrade. Users unable to upgrade may avoid this issue by parsing only CVS

pandatix go-cvss UPGRADE

Affected: >= 0.2.0 and < 0.4.0

Fixed in: 0.4.0

Safe to downgrade to: a release before 0.2.0

1. Check installed version

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

2. UPGRADE to 0.4.0 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade go-cvss

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 0.2.0 (Debian / Ubuntu)

apt-cache madison go-cvss sudo apt install go-cvss=<VERSION_BEFORE_0.2.0> sudo apt-mark hold go-cvss

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

dnf --showduplicates list go-cvss sudo dnf downgrade go-cvss-<VERSION_BEFORE_0.2.0> sudo dnf versionlock add go-cvss

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.
