Stack-based buffer overflow in the LiveJournal support (hooks/ljhook.cc) in CenterICQ 4.9.11 through 4.21.0, when using unofficial LiveJournal servers, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code by adding the victim as a friend and using long (1) username and (2) real name strings.
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.
