Buffer overflow in the RFC1413 (ident) client in cfingerd 1.4.3-3 allows remote IDENT servers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted response.

Security readout for executives and security teams

CVE-2013-1049 affects cfingerd, a legacy finger daemon. A malicious remote IDENT server can send a crafted response that may crash cfingerd and possibly run code. The business concern is mainly older Linux systems still running cfingerd or packaged versions tied to Debian and Ubuntu advisories. Exposure is most likely on legacy Debian or Ubuntu systems where cfingerd is installed and reachable in workflows that trigger IDENT lookups. The CVE record does not provide structured CPEs, so package inventory is more reliable than product-name matching alone. Treat this as a targeted legacy-service cleanup item. It is not supported by public active-exploitation evidence, but affected hosts could face service crashes or possible code execution. Prioritize internet-facing or sensitive legacy systems first. Mitigation focus: Apply vendor updates referenced by Debian DSA-2635 where cfingerd is installed.; Check Ubuntu and Debian bug guidance for affected package status.; Disable or remove cfingerd if the service is no longer required..
