Description Andrej Nemec 2016-06-22 08:29:46 UTC
A buffer vulnerability exists in the handling of the MXIT protocol in Pidgin. Specially crafted MXIT data sent by the server could potentially result in an out of bounds write of one byte. A malicious server can send a negative content-length in response to a HTTP request triggering the vulnerability.
