CVE-2026-52134 1 Mz-automation 1 Libiec61850 2026-08-03 9.8 Critical
An issue in the parseGoosePayload() function (/goose/goose_receiver.c) of libiec61850 v1.6 allows attackers to bypass authentication via a captured GOOSE frame.
CVE-2026-56758 1 Mz-automation 1 Libiec61850 2026-08-03 6.5 Medium
The ACSE layer contains a flaw in the processing of AARQ PDUs during MMS connection establishment. When parsing certain fields within the calling AP title, an attacker controlled length value of zero or one may cause the parser to read past the end of a heap buffer.
CVE-2026-66349 1 Mz-automation 1 Libiec61850 2026-08-03 6.5 Medium
The MMS server connection handler contains a flaw in its processing of BER-encoded request data. When an MMS confirmed request PDU containing an extended BER tag is received over an established session, the decoder may advance its internal buffer incorrectly due to a missing bounds check. This results in a one byte heap out-of-bounds read and causes the MMS service process to terminate, leading to a denial-of-service condition.
CVE-2026-18582 1 Mz-automation 1 Libiec61850 2026-08-03 5.3 Medium
A security flaw has been discovered in mz-automation libiec61850 up to 1.6.1.

The attack can be initiated remotely. The exploit has been made available to the public and could be used for attacks. Upgrading to version 1.6.2 is capable of addressing this issue. Patch name: 062062daf4cb50c7aa76e01d6fb4d58fc9278a7d. Upgrading the affected component is recommended. The vendor was contacted early about this disclosure.
CVE-2026-66369 1 Mz-automation 1 Libiec61850 2026-07-31 6.5 Medium
The GOOSE parser contains an off-by-one boundary-handling flaw that can be triggered by a single unauthenticated Layer-2 multicast frame on the process bus. When specific GOOSE message fields are processed, the parser advances its internal buffer position incorrectly, resulting in a heap out-of-bounds read. On affected platforms, this condition reliably terminates the subscriber process and causes a denial-of-service.
CVE-2026-66720 1 Mz-automation 1 Libiec61850 2026-07-31 6.5 Medium
The GOOSE subscriber component improperly validates the UTC timestamp field in unauthenticated IEC 61850 GOOSE (EtherType 0x88B8) Layer-2 multicast messages. A specially crafted GOOSE frame containing an undersized timestamp field can trigger a heap out-of-bounds read during message processing, causing the process to crash and resulting in a denial-of-service condition.
CVE-2026-63550 1 Mz-automation 1 Libiec61850 2026-07-31 6.5 Medium
The MMS BER decoder contains a boundary-handling flaw in the processing of certain fields within confirmed-request messages. When a crafted BER-encoded element is received over an established MMS session (TCP port 102), the decoder may advance its internal read position incorrectly, leading to a heap out-of-bounds read. This condition causes the MMS handling process to terminate unexpectedly, resulting in a denial-of-service.
CVE-2026-65421 1 Mz-automation 1 Libiec61850 2026-07-31 6.5 Medium
The MMS BER decoder contains a flaw in decoding fixed-width BER fields (boolean/integer): an attacker-supplied length value is not validated, causing a read past the end of a heap buffer. This leads to termination of the MMS service process and a denial-of-service condition.
CVE-2026-66364 1 Mz-automation 1 Libiec61850 2026-07-31 6.5 Medium
The GOOSE payload parser contains a boundary handling flaw that can be triggered by a single unauthenticated Layer 2 multicast frame on the process bus. When processing specific payload fields, an attacker controlled inner element length may exceed its enclosing length, causing the parser to over read by one byte. This out-of-bounds read reliably terminates the subscriber process, resulting in a denial-of-service condition.
CVE-2026-66360 1 Mz-automation 1 Libiec61850 2026-07-31 7.5 High
The ISO Presentation layer contains a flaw in the handling of specific parameters during normal mode negotiation. A missing length check in the processing of the encoded presentation data allows an attacker controlled field with a zero length value to trigger a bounded heap over read. This condition occurs before MMS session establishment, a crafted TCP/102 connection attempt can trigger the issue. The resulting over read causes the process to terminate, leading to a denial of service condition.
CVE-2026-50039 1 Mz-automation 1 Libiec61850 2026-07-24 7.5 High
The affected product is vulnerable to a stack-based buffer overflow, which may allow an attacker to cause a memory corruption via a Read Request.
CVE-2026-49035 1 Mz-automation 1 Libiec61850 2026-07-24 8.1 High
The affected product is vulnerable to a heap-based buffer overflow via a crafted MMS Initiate request. Remote code execution (RCE) has been demonstrated when ASLR is disabled; memory corruption or denial of service may occur in configurations where ASLR is enabled.
CVE-2026-50103 1 Mz-automation 1 Libiec61850 2026-07-24 6.5 Medium
A NULL pointer dereference in the L2 GOOSE and R-GOOSE shared parser, which may allow a network-adjacent attacker to crash a subscribing application by sending a crafted GOOSE frame containing a malformed TLV value.
CVE-2026-50032 1 Mz-automation 1 Libiec61850 2026-07-24 7.5 High
A NULL pointer dereference in the MMS Write Named Variable List handler, which may allow a network adjacent attacker to crash the server by sending a WriteRequest with an empty listOfData field.
