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.
