USN-5241-1: QtSvg vulnerabilities

Releases

• Ubuntu 18.04 ESM

Packages

• qtsvg-opensource-src - Qt 5 SVG module

Details

It was discovered that QtSvg incorrectly handled certain malformed SVG
images. If a user or automated system were tricked into opening a specially
crafted image file, a remote attacker could use this issue to cause QtSvg
to crash, resulting in a denial of service, or possibly execute arbitrary
code.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 18.04

• libqt5svg5 - 5.9.5-0ubuntu1.1

In general, a standard system update will make all the necessary changes.
