Use-after-free vulnerability in Mono, when Moonlight 2.x before 2.4.1 or 3.x before 3.99.3 is used, allows remote attackers to cause a denial of service (plugin crash) or obtain sensitive information via vectors related to member data in a resurrected MonoThread instance.

Security readout for executives and security teams

CVE-2011-0992 is a legacy Mono/Moonlight flaw. Vulnerable Moonlight versions could let a remote attacker crash the browser plugin or expose sensitive information. Business urgency is mainly for environments still running obsolete Moonlight browser-plugin technology; environments without Moonlight exposure appear unlikely to be affected based on the supplied sources. Exposure is likely limited to legacy endpoints, kiosks, or application stacks that still use Moonlight with Mono. The supplied affected-product metadata is incomplete, so validate by installed package/plugin versions rather than relying on CPE matching. Handle as a legacy-technology cleanup item unless Moonlight is confirmed in production. If present, prioritize removal or upgrade because remote crash and information disclosure are possible, and the technology is obsolete. Mitigation focus: Upgrade Moonlight 2.x to 2.4.1 or later if still required.; Upgrade Moonlight 3.x to 3.99.3 or later if still required.; Remove or disable Moonlight where business use no longer exists..
