The version of Pidgin installed on the remote host is earlier than 2.10.2 and is potentially affected by the following issues :
A denial of service vulnerability (NULL pointer dereference) in the ‘pidgin_conv_chat_rename_user’ function in ‘gtkconv.c’. Remote attackers can trigger the vulnerability by performing certain types of nickname changes while in an XMPP chat room. (CVE-2011-4939)
The msn_oim_report_to_user function in oim.c allows remote servers to cause an application crash by sending an OIM message without UTF-8 encoding. (CVE-2012-1178)
