Red Hat Product Errata RHSA-2011:0616 0 normal SHIPPED_LIVE Low: pidgin security and bug fix update 2011-05-19 11:09:02 UTC

Description Huzaifa S. Sidhpurwala 2011-03-14 08:42:15 UTC
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.
