This can lead to a\ncrash  when receiving strings that aren't UTF-8 (CVE-2012-6152).\n\nA remote XMPP user can trigger a crash on some systems by sending a\nmessage with a timestamp in the distant future (CVE-2013-6477).\n\nlibX11 forcefully exits causing a crash when Pidgin tries to create an\nexceptionally wide tooltip window when hovering the pointer over a long\nURL (CVE-2013-6478).\n\nA malicious server or man-in-the-middle could send a malformed HTTP\nresponse that could lead to a crash (CVE-2013-6479).\n\nThe Yahoo! protocol plugin failed to validate a length field before trying\nto read from a buffer, which could result in reading past the end of the\nbuffer which could cause a crash when reading a P2P message\n(CVE-2013-6481).\n\nNULL pointer dereferences in the MSN protocol plugin due to a malformed\nContent-Length header, or a malicious server or man-in-the-middle sending\na specially crafted OIM data XML response or SOAP response\n(CVE-2013-6482).\n\nThe XMPP protocol plugin failed to ensure that iq replies came from the\nperson they were sent to.
