CVE-2011-2943  (opens in a new tab)

How to fix?

Upgrade Debian:10 pidgin to version 2.10.0-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream pidgin package and not the pidgin package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

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.
