 Mandriva Linux Security Advisory                         MDVSA-2011:132
 http://www.mandriva.com/security/

 Package : pidgin
 Date    : September 6, 2011
 Affected: 2009.0, 2010.1, Enterprise Server 5.0
 _______________________________________________________________________

 Problem Description:

 Multiple vulnerabilities has 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. Using
 this structure, possibly containing a huge width and height, could
 lead to the application being terminated due to excessive memory use
 (CVE-2011-2485).
 
 Certain characters in the nicknames of IRC users can trigger a
 null pointer dereference in the IRC protocol plugin's handling of
 responses to WHO requests. This can cause a crash on some operating
 systems. Clients based on libpurple 2.8.0 through 2.9.0 are affected
 (CVE-2011-2943).
 
 Incorrect handling of HTTP 100 responses in the MSN protocol plugin
 can cause the application to attempt to access memory that it does
 not have access to. This only affects users who have turned on the
 HTTP connection method for their accounts (it's off by default). This
 might only be triggerable by a malicious server and not a malicious
 peer. We believe remote code execution is not possible (CVE-2011-3184).
 
 Packages for 2009.0 are provided as of the Extended Maintenance
 Program. Please visit this link to learn more:

 This update provides pidgin 2.10.0, which is not vulnerable to
 these issues.
