Heap-based buffer overflow in hfaxd in HylaFAX+ 5.2.4 through 5.5.3, when using LDAP authentication, might allow remote attackers to cause a denial of service (child hang) or execute arbitrary code via a long USER command.
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.
