An information leak exists in the handling of the MXIT protocol in Pidgin. Specially crafted MXIT data sent to the server could potentially result in an out of bounds read. A user could be convinced to enter a particular string which would then get converted incorrectly and could lead to a potential out-of-bounds read.
