CVE-2026-42854

arduino-esp32 is an Arduino core for the ESP32, ESP32-S2, ESP32-S3, ESP32-C3, ESP32-C6 and ESP32-H2 microcontrollers. Prior to 3.3.8, the WebServer multipart form parser in arduino-esp32 allocates a Variable Length Array VLA on the stack whose size is derived from an attacker-controlled HTTP head...

CVE-2026-42854

Summary: The Arduino-ESP32 core is affected by a stack overflow in the WebServer multipart boundary parser. A boundary derived from the HTTP header (Content-Type: multipart/form-data; boundary=...) with length > ~8000 can overflow the 8192-byte loopTask stack, potentially enabling remote code ...

QEMU: nbd: reachable assertion failure in nbd_negotiate_send_rep_verr via remote client

An assertion failure issue was found in the Network Block DeviceNBD Server of the QEMU. This flaw occurs when an nbd-client sends a spec-compliant request that is near the boundary of maximum permitted request length. A remote nbd-client could use this flaw to crash the qemu-nbd server resulting ...

Apache Commons Fileupload 1.3.1 DOS(CVE-2016-3092)-vulnerability warning-the black bar safety net

Last year the commons-fileupload official announcements Commons Fileupload of a security vulnerability CVE-2016-3092, in the Commons FileUpload 1.3.2 repair. because at that time the security components use the Commons FileUpload 1.3.1 release, so with a bit of this vulnerability. Shortly before...

tomcat: Usage of vulnerable FileUpload package can result in denial of service

A denial of service vulnerability was identified in Commons FileUpload that occurred when the length of the multipart boundary was just below the size of the buffer 4096 bytes used to read the uploaded file if the boundary was the typical tens of bytes long...
