DESCRIPTION:
Some security issues have been reported in Pidgin, which can be
exploited by malicious, local users to disclose potentially sensitive
information.

The security issues are caused due to the "md5_uninit()",
"md4_uninit()", "des_uninit()", "des3_uninit()", "rc4_uninit()", and
"purple_cipher_context_destroy()" functions in libpurple/cipher.c not
properly clearing certain sensitive structures prior to freeing them,
which can lead to potentially sensitive information remaining in
memory.

The security issues are reported in versions prior to 2.7.10.

SOLUTION:
Update to version 2.7.10.

PROVIDED AND/OR DISCOVERED BY:
The vendor credits Julia Lawall.
