"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:

This update provides pidgin 2.7.11, which is not vulnerable to these
issues."
