TITLE:
Evolution Base64 Integer Overflow Vulnerabilities

SECUNIA ADVISORY ID:
SA34334

VERIFY ADVISORY:
http://secunia.com/advisories/34334/

DESCRIPTION:
Some vulnerabilities have been reported in Evolution, which can
potentially be exploited by malicious people to compromise a user's
system.

The vulnerabilities are caused due to integer overflow errors within
the "_evc_base64_encode_simple()" function in
addressbook/libebook/e-vcard.c and the "camel_base64_encode_simple()"
function in camel/camel-mime-utils.c of evolution-data-server. These
can be exploited to cause heap-based buffer overflows by e.g.
tricking a user into connecting to a malicious LDAP backend or
connection to a malicious server using NTLM SASL authentication.

This is related to:
SA34267

SOLUTION:
Update to version 2.22.0 or later.

PROVIDED AND/OR DISCOVERED BY:
Originally reported in GLib by Diego Pettenò. Reported in Evolution
by Thomas Hoger.
