CRITICAL 9.8REMOTEWATCHLISTUPGRADEMITIGATEMITIGATE
CVE-2022-32207 is a critical-severity flaw (CVSS 9.8) affecting curl, fedora, debian linux. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
When curl < 7.84.0 saves cookies, alt-svc and hsts data to local files, it makes the operation atomic by finalizing the operation with a rename from a temporary name to the final target file name.In that rename operation, it might accidentally *widen* the permissions for the target file, leaving the updated file accessible to more users than intended.
Why this priority
- Critical severity
- EPSS top 4%: very likely to be exploited
- Public exploit reference
- CISA SSVC: automatable with total technical impact
- Remotely exploitable, no login, no user action
- On your watchlist

haxx curl UPGRADE
Affected: >= 7.69.0 and < 7.84.0
Fixed in: 7.84.0
Safe to downgrade to: a release before 7.69.0
1. Check installed version
apt-cache policy curl || rpm -q curl || curl --version
2. UPGRADE to 7.84.0 (Debian / Ubuntu)
sudo apt update && sudo apt install --only-upgrade curl
2. UPGRADE (RHEL / Amazon Linux / Fedora)
sudo dnf upgrade curl
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 7.69.0 (Debian / Ubuntu)
apt-cache madison curl
sudo apt install curl=<VERSION_BEFORE_7.69.0>
sudo apt-mark hold curl
3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list curl
sudo dnf downgrade curl-<VERSION_BEFORE_7.69.0>
sudo dnf versionlock add curl
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.
