CVE-2024-12088: A flaw was found in rsync

This month

MEDIUM 6.5WATCHLISTUPGRADEDOWNGRADEDOWNGRADE

CVE-2024-12088 is a medium-severity flaw (CVSS 6.5) affecting rsync, discovery, openshift container platform. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

A flaw was found in rsync. When using the `--safe-links` option, the rsync client fails to properly verify if a symbolic link destination sent from the server contains another symbolic link within it. This results in a path traversal vulnerability, which may lead to arbitrary file write outside the desired directory.

samba rsync UPGRADE

Affected: <= 3.3.0

Fixed in: newer than 3.3.0

Safe to downgrade to: no unaffected older release

1. Check installed version

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

2. UPGRADE to newer than 3.3.0 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade rsync

Note

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

redhat discovery DOWNGRADE

Affected: 1.14

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.14

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 1.14 (Debian / Ubuntu)

apt-cache madison discovery sudo apt install discovery=<VERSION_BEFORE_1.14> sudo apt-mark hold discovery

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list discovery sudo dnf downgrade discovery-<VERSION_BEFORE_1.14> sudo dnf versionlock add discovery

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.

redhat openshift container platform DOWNGRADE

Affected: 4.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 4.0

1. Check installed version

apt-cache policy openshift-container-platform || rpm -q openshift-container-platform || openshift-container-platform --version

2. No fixed release: DOWNGRADE to a release before 4.0 (Debian / Ubuntu)

apt-cache madison openshift-container-platform sudo apt install openshift-container-platform=<VERSION_BEFORE_4.0> sudo apt-mark hold openshift-container-platform

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list openshift-container-platform sudo dnf downgrade openshift-container-platform-<VERSION_BEFORE_4.0> sudo dnf versionlock add openshift-container-platform

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
