 Package : pidgin
 Date    : March 21, 2011
 Affected: 2009.0, 2010.0, 2010.1, Enterprise Server 5.0
 _______________________________________________________________________

 Problem Description:

 Multiple vulnerabilities has been identified and fixed in pidgin:
 
 It was discovered that libpurple versions prior to 2.7.10 do not
 properly clear certain data structures used in libpurple/cipher.c
 prior to freeing. An attacker could potentially extract partial
 information from memory regions freed by libpurple.
 
 The Yahoo protocol plugin in libpurple versions 2.6.0 through 2.7.10
 do not properly handle malformed YMSG packets, leading to NULL pointer
 dereferences and application crash (CVE-2011-1091).
 
 Packages for 2009.0 are provided as of the Extended Maintenance
 Program. Please visit this link to learn more:
 http://store.mandriva.com/product_info.php?cPath=149&products_id=490
 
 This update provides pidgin 2.7.11, which is not vulnerable to
 these issues.
