CWE-400  (opens in a new tab)

How to fix?

Upgrade pidgin to version 2.10.0 or higher.

Overview

Affected versions of this package are vulnerable to Denial of Service (DoS). The irc_msg_who function in msgs.c in the IRC protocol plugin in libpurple 2.8.0 through 2.9.0 in Pidgin before 2.10.0 does not properly validate characters in nicknames, which allows user-assisted remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted nickname that is not properly handled in a WHO response.
