USN-6216-1: lib3mf vulnerability

Releases

• Ubuntu 20.04 LTS

Packages

• lib3mf - Lib3MF is a C++ implementation of the 3D Manufacturing Format

Details

It was discovered that lib3mf did not properly manage memory under
certain circumstances. If a user were tricked into opening a specially
crafted 3MF file, a local attacker could possibly use this issue to
cause applications using lib3mf 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 20.04

• lib3mf1 - 1.8.1+ds-3ubuntu0.2
• lib3mf-dev - 1.8.1+ds-3ubuntu0.2

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