HIGH 7.5REMOTEUPGRADE

CVE-2001-0950 is a high-severity flaw (CVSS 7.5) affecting enterprise validation authority. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

ValiCert Enterprise Validation Authority (EVA) Administration Server 3.3 through 4.2.1 uses insufficiently random data to (1) generate session tokens for HSMs using the C rand function, or (2) generate certificates or keys using /dev/urandom instead of another source which blocks when the entropy pool is low, which could make it easier for local or remote attackers to steal tokens or certificates via brute force guessing.

valicert enterprise validation authority UPGRADE

Affected: >= 3.3 and <= 4.2.1

Fixed in: newer than 4.2.1

Safe to downgrade to: a release before 3.3

1. Check installed version

apt-cache policy enterprise-validation-authority || rpm -q enterprise-validation-authority || enterprise-validation-authority --version

2. UPGRADE to newer than 4.2.1 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade enterprise-validation-authority

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade enterprise-validation-authority

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 3.3 (Debian / Ubuntu)

apt-cache madison enterprise-validation-authority sudo apt install enterprise-validation-authority=<VERSION_BEFORE_3.3> sudo apt-mark hold enterprise-validation-authority

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

dnf --showduplicates list enterprise-validation-authority sudo dnf downgrade enterprise-validation-authority-<VERSION_BEFORE_3.3> sudo dnf versionlock add enterprise-validation-authority

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.
