Description

Stack-based buffer overflow in libpixman, as used in Pale Moon before 15.4 and possibly other products, has unspecified impact and context-dependent attack vectors.

Affected products

Red Hat Enterprise Linux: 6.0
RedHat Enterprise Virtualization: 3.0

How to fix

Upgrade to a fixed version: Palemoon Pale Moon 15.4. Check the vendor advisory for mitigations.
