CVSS: 9.8EPSS: 1%CPEs: 1EXPL: 0CVE-2020-15158 – Heap buffer overflow in libIEC61850
https://notcve.org/view.php?id=CVE-2020-15158
In libIEC61850 before version 1.4.3, when a message with COTP message length field with value < 4 is received an integer underflow will happen leading to heap buffer overflow. This can cause an application crash or on some platforms even the execution of remote code. If your application is used in open networks or there are untrusted nodes in the network it is highly recommend to apply the patch. This was patched with commit 033ab5b. Users of version 1.4.x should upgrade to version 1.4.3 when available. • https://github.com/mz-automation/libiec61850/commit/033ab5b6488250c8c3b838f25a7cbc3e099230bb https://github.com/mz-automation/libiec61850/issues/250 https://github.com/mz-automation/libiec61850/security/advisories/GHSA-pq77-fmf7-hjw8 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow CWE-191: Integer Underflow (Wrap or Wraparound) •
