CVE-2020-12049 is a denial-of-service vulnerability affecting D-Bus versions 1.3.0 through 1.12.17, impacting products like Canonical D-Bus and Ubuntu Linux. A local attacker can exploit this by sending messages exceeding the per-message file descriptor limit, causing the D-Bus daemon to leak file descriptors and eventually reach its system-wide limit. This medium-severity vulnerability (CVSS 5.5) has low attack complexity and requires local access, leading to a denial of service for subsequent D-Bus clients. There is no evidence of active exploitation, public exploit code, or significant community discussion, indicating a low current threat level.
