USN-3962-1: libpng vulnerability

Releases

• Ubuntu 18.10
• Ubuntu 18.04 ESM

Packages

• libpng1.6 - PNG (Portable Network Graphics) file library

Details

It was discovered that libpng incorrectly handled certain memory
operations. If a user or automated system were tricked into opening a
specially crafted PNG file, a remote attacker could use this issue to
cause libpng 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 18.10

• libpng16-16 - 1.6.34-2ubuntu0.1

Ubuntu 18.04

• libpng16-16 - 1.6.34-1ubuntu0.18.04.2

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