CVE-2023-28448 is a medium-severity flaw (CVSS 5.7) affecting versionize. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Versionize is a framework for version tolerant serializion/deserialization of Rust data structures, designed for usecases that need fast deserialization times and minimal size overhead. An issue was discovered in the ‘Versionize::deserialize’ implementation provided by the ‘versionize’ crate for ‘vmm_sys_utils::fam::FamStructWrapper', which can lead to out of bounds memory accesses. The impact started with version 0.1.1. The issue was corrected i

versionize project versionize UPGRADE

Affected: >= 0.1.1 and < 0.1.10

Fixed in: 0.1.10

Safe to downgrade to: a release before 0.1.1

1. Check installed version

apt-cache policy versionize || rpm -q versionize || versionize --version

2. UPGRADE to 0.1.10 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade versionize

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade versionize

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 0.1.1 (Debian / Ubuntu)

apt-cache madison versionize sudo apt install versionize=<VERSION_BEFORE_0.1.1> sudo apt-mark hold versionize

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

dnf --showduplicates list versionize sudo dnf downgrade versionize-<VERSION_BEFORE_0.1.1> sudo dnf versionlock add versionize

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.
