An issue was discovered in Quagga through 1.2.4. Unsafe chown/chmod operations in the suggested spec file allow users (with control of the non-root-owned directory /etc/quagga) to escalate their privileges to root upon package installation or update.
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
