Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple integer overflows in CamlImages might result in the remote |
| 19 |
execution of arbitrary code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
CamlImages is an image processing library for Objective Caml. |
| 25 |
|
| 26 |

Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Tielei Wang reported multiple integer overflows, possibly leading to |
| 38 |
heap-based buffer overflows in the (1) read_png_file() and |
| 39 |
read_png_file_as_rgb24() functions, when processing a PNG image |
| 40 |
(CVE-2009-2295) and (2) gifread.c and jpegread.c files when processing |
| 41 |
GIF or JPEG images (CVE-2009-2660). |
| 42 |
|
| 43 |
Other integer overflows were also found in tiffread.c (CVE-2009-3296). |
| 44 |
|
| 45 |
Impact |
| 46 |
====== |
| 47 |
|
| 48 |
A remote attacker could entice a user to open a specially crafted, |
| 49 |
overly large PNG, GIF, TIFF, or JPEG image using an application that |
| 50 |
uses the CamlImages library, possibly resulting in the execution of |
| 51 |
arbitrary code with the privileges of the user running the application. |
| 52 |
|
| 53 |
Workaround |
| 54 |
========== |
| 55 |
|
| 56 |
There is no known workaround at this time. |
| 57 |
|
| 58 |
Resolution |
| 59 |
========== |
| 60 |
|
| 61 |
All CamlImages users should upgrade to the latest version: |
| 62 |
|
| 63 |
# emerge --sync |
| 64 |
# emerge --ask --oneshot --verbose =dev-ml/camlimages-3.0.2 |
| 65 |
