CVE-2019-7307 is a high-severity flaw (CVSS 7.0) affecting apport. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Apport before versions 2.14.1-0ubuntu3.29+esm1, 2.20.1-0ubuntu2.19, 2.20.9-0ubuntu7.7, 2.20.10-0ubuntu27.1, 2.20.11-0ubuntu5 contained a TOCTTOU vulnerability when reading the users ~/.apport-ignore.xml file, which allows a local attacker to replace this file with a symlink to any other file on the system and so cause Apport to include the contents of this other file in the resulting crash report. The crash report could then be read by that user

apport project apport DOWNGRADE

Affected: 2.14.1 · 2.20.1 · 2.20.9 · 2.20.10

Fixed in: no fixed release known

Safe to downgrade to: a release before 2.14.1

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 2.14.1 (Debian / Ubuntu)

apt-cache madison apport sudo apt install apport=<VERSION_BEFORE_2.14.1> sudo apt-mark hold apport

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

dnf --showduplicates list apport sudo dnf downgrade apport-<VERSION_BEFORE_2.14.1> sudo dnf versionlock add apport

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.
