VAR-201702-0577
Vulnerability from variot - Updated: 2023-12-18 13:24Unisys 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. Unisys Libra 43xx and so on are all MCP-based application system architectures developed by Unisys Corporation of the United States. MCP-FIRMWARE 40.0 versions prior to 40.0IC4 Build 270 in Unisys Libra 43xx, 63xx, 83xx and FS600 class systems have a security vulnerability. A remote attacker could exploit this vulnerability to cause a denial of service (data corruption and system crash)
