Synopsis |
16 |
======== |
17 |
|
18 |
Multiple integer overflows might allow for the execution of arbitrary |
19 |
code when performing base64 conversion. |

=========== |
38 |
|
39 |
Diego E. Pettenò reported multiple integer overflows in glib/gbase64.c |
40 |
when converting a long string from or to a base64 representation. |
41 |
|
42 |
Impact |
43 |
====== |
44 |
|
45 |
A remote attacker could entice a user or automated system to perform a |
46 |
base64 conversion via an application using GLib, possibly resulting in |
47 |
the execution of arbitrary code. |
48 |
|
49 |
Workaround |
50 |
========== |
51 |
|
52 |
There is no known workaround at this time. |
53 |
