CWE-119Published: April 5, 2012· Updated: Jun 16, 2026
Official Description
Buffer overflow in the OSPFv2 implementation in ospfd in Quagga before 0.99.20.1 allows remote attackers to cause a denial of service (daemon crash) via a Link State Update (aka LS Update) packet containing a network-LSA link-state advertisement for which the data-structure length is smaller than the value in the Length header field.
Technical Analysis
CVE-2012-0250 requires adjacent network access, limiting remote exploitation but still posing risk in shared or local network environments.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
From a weakness classification perspective (CWE-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
