CVE-2024-2410: The JsonToBinaryStream() function is part of the protocol buffers C++ implementation and is used to parse JSON

Routine

HIGH 7.6UPGRADE

CVE-2024-2410 is a high-severity flaw (CVSS 7.6) affecting protobuf. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

The JsonToBinaryStream() function is part of the protocol buffers C++ implementation and is used to parse JSON from a stream. If the input is broken up into separate chunks in a certain way, the parser will attempt to read bytes from a chunk that has already been freed.

Why this priority

High severity

A fixed release or distro patch exists.

google protobuf UPGRADE

Affected: >= 4.22.0 and < 4.25.0

Fixed in: 4.25.0

Safe to downgrade to: a release before 4.22.0

1. Check installed version

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

2. UPGRADE to 4.25.0 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade protobuf

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 4.22.0 (Debian / Ubuntu)

apt-cache madison protobuf sudo apt install protobuf=<VERSION_BEFORE_4.22.0> sudo apt-mark hold protobuf

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

dnf --showduplicates list protobuf sudo dnf downgrade protobuf-<VERSION_BEFORE_4.22.0> sudo dnf versionlock add protobuf

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.
