Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

Description

An exploitable code execution vulnerability exists in the Levin deserialization functionality of the Epee library, as used in Monero 'Lithium Luna' (v0.12.2.0-master-ffab6700) and other cryptocurrencies. A specially crafted network packet can cause a logic flaw, resulting in code execution. An attacker can send a packet to trigger this vulnerability.
