Cisco Unified Communications Manager (aka CUCM or Unified CM) allows remote attackers to cause a denial of service (service restart) via a crafted SIP message, aka Bug ID CSCub54349.
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.
