    • CVE-2018-0156: Smart Install Remote Code Execution.
    • CVE-2017-6736: SNMP Remote Code Execution.
    • CVE-2017-12235: "JAVA Deserialization" vulnerability in the web GUI.
  2. Stability Enhancements: Resolves memory leaks observed in long-running SSH sessions and MAC address table inconsistencies.
  3. PoE Improvements: For the 3560E-48PD, this update improves Power over Ethernet (PoE) negotiation with modern 802.3af/at devices.

If you see -UPD- appended, it likely means Cisco released a silent hotfix—replacing the original 152-4.e10.bin with a patched version that fixes a specific regression (like a DHCP snooping crash) without incrementing to E11.
