Unisys : Security Vulnerabilities, CVEs, Published In 2017 (Denial of service)

Unisys Libra 64xx and 84xx and FS601 class systems with MCP-FIRMWARE before 43.211 allow remote authenticated users to cause a denial of service (program crash) or have unspecified other impact via vectors related to incorrect literal handling, which trigger CPM stack corruption.

The TCP/IP networking module in Unisys ClearPath MCP systems with TCP-IP-SW 57.1 before 57.152, 58.1 before 58.142, or 59.1 before 59.172, when running a TLS 1.2 service, allows remote attackers to cause a denial of service (network connectivity disruption) via a client hello with a signature_algorithms extension above those defined in RFC 5246, which triggers a full memory dump.

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.
