CVE-2011-2943

Status Candidate

Overview

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.

Mandriva Linux Security Advisory 2011-132-1

Mandriva Linux Security Advisory 2011-132 - Multiple vulnerabilities have been identified and fixed in pidgin. It was found that the gdk-pixbuf GIF image loader routine gdk_pixbuf__gif_image_load() did not properly handle certain return values from its subroutines. A remote attacker could provide a specially-crafted GIF image, which, once opened in Pidgin, would lead gdk-pixbuf to return a partially initialized pixbuf structure. Various other issues were also addressed.
