CVE-2015-4049

Estado: ModificadaMedia (6.8)—

Unisys Libra 43xx, 63xx, and 83xx, and FS600 class systems with MCP-FIRMWARE 40.0 before 40.0IC4 Build 270 might allow remote authenticated users to cause a denial of service (data corruption or system crash) via vectors related to using program operators during EPSILON (level 5) based codefiles at peak memory usage, which triggers CPM stack corruption.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
