Stack-based buffer overflow in Firebird 2.1.3 through 2.1.5 before 18514, and 2.5.1 through 2.5.3 before 26623, on Windows allows remote attackers to execute arbitrary code via a crafted packet to TCP port 3050, related to a missing size check during extraction of a group number from CNCT information.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
