Pidgin < 2.10.2 Multiple DoS

Medium Nessus Plugin ID 58410


An instant messaging client installed on the remote Windows host is potentially affected by multiple denial of service vulnerabilities.


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)


Upgrade to Pidgin 2.10.2 or later.
