TITLE:
GLib Base64 Integer Overflow Vulnerabilities

SECUNIA ADVISORY ID:
SA34267

VERIFY ADVISORY:
http://secunia.com/advisories/34267/

DESCRIPTION:
Some vulnerabilities have been reported in GLib, which can
potentially be exploited by malicious people to compromise an
application using the library.

The vulnerabilities are caused due to integer overflows within the
"g_base64_encode()" and "g_base64_decode()" functions in
glib/base64.c. This can be exploited to cause a heap-based buffer
overflow by e.g. tricking an application using the library into
encoding or decoding specially crafted input.

SOLUTION:
Update to version 2.20.0.
