CVE-2017-14226 is a high-severity flaw (CVSS 7.5) affecting libreoffice, libwpd. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

WP1StylesListener.cpp, WP5StylesListener.cpp, and WP42StylesListener.cpp in libwpd 0.10.1 mishandle iterators, which allows remote attackers to cause a denial of service (heap-based buffer over-read in the WPXTableList class in WPXTable.cpp). This vulnerability can be triggered in LibreOffice before 5.3.7. It may lead to suffering a remote attack against a LibreOffice application.

Why this priority

libreoffice libreoffice UPGRADE

Affected: <= 5.3.6

Fixed in: newer than 5.3.6

Safe to downgrade to: no unaffected older release

1. Check installed version

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

2. UPGRADE to newer than 5.3.6 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

libwpd libwpd DOWNGRADE

Affected: 0.10.1

Fixed in: no fixed release known

Safe to downgrade to: a release before 0.10.1

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 0.10.1 (Debian / Ubuntu)

apt-cache madison libwpd sudo apt install libwpd=<VERSION_BEFORE_0.10.1> sudo apt-mark hold libwpd

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

dnf --showduplicates list libwpd sudo dnf downgrade libwpd-<VERSION_BEFORE_0.10.1> sudo dnf versionlock add libwpd

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.
