Synopsis |
16 |
======== |
17 |
|
18 |
libgsf improperly allocates memory allowing for a heap overflow and |
19 |
possibly the execution of arbitrary code. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
The GNOME Structured File Library is an I/O library that can read and |
25 |
write common file types and handle structured formats that provide |
26 |
file-system-in-a-file semantics. |
27 |
|
28 |
Affected packages |
29 |
================= |
30 |
|
31 |
------------------------------------------------------------------- |
32 |
Package / Vulnerable / Unaffected |
33 |
------------------------------------------------------------------- |
34 |
1 gnome-extra/libgsf < 1.14.2 >= 1.14.2 |
35 |
|
36 |
Description |
37 |
=========== |
38 |
|
39 |
"infamous41md" has discovered that the "ole_init_info" function may |
40 |
allocate too little memory for storing the contents of an OLE document, |
41 |
resulting in a heap buffer overflow. |
42 |
|
43 |
Impact |
44 |
====== |
45 |
|
46 |
An attacker could entice a user to open a specially crafted OLE |
47 |
document, and possibly execute arbitrary code with the rights of the |
48 |
user opening the document. |
49 |
|
50 |
Workaround |
51 |
========== |
52 |
|
53 |
There is no known workaround at this time. |
54 |
|
55 |
Resolution |
56 |
========== |
57 |
|
58 |
All libgsf users should upgrade to the latest version: |
59 |
|
60 |
# emerge --sync |
61 |
# emerge --ask --oneshot --verbose ">=gnome-extra/libgsf-1.14.2" |
62 |
