Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple memory management errors in JasPer might lead to execution of |
| 19 |
arbitrary code via jpeg2k files. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
The JasPer Project is an open-source initiative to provide a free |
| 25 |
software-based reference implementation of the codec specified in the |
| 26 |
JPEG-2000 Part-1 (jpeg2k) standard. |
| 27 |
|
| 28 |
Affected packages |
| 29 |
================= |
| 30 |
|
| 31 |
------------------------------------------------------------------- |
| 32 |
Package / Vulnerable / Unaffected |
| 33 |
------------------------------------------------------------------- |

Description |
| 37 |
=========== |
| 38 |
|
| 39 |
Marc Espie and Christian Weisgerber have discovered multiple |
| 40 |
vulnerabilities in JasPer: |
| 41 |
|
| 42 |
* Multiple integer overflows might allow for insufficient memory |
| 43 |
allocation, leading to heap-based buffer overflows (CVE-2008-3520). |
| 44 |
|
| 45 |
* The jas_stream_printf() function in libjasper/base/jas_stream.c |
| 46 |
uses vsprintf() to write user-provided data to a static to a buffer, |
| 47 |
leading to an overflow (CVE-2008-3522). |
| 48 |
|
| 49 |
Impact |
| 50 |
====== |
| 51 |
|
| 52 |
Remote attackers could entice a user or automated system to process |
| 53 |
specially crafted jpeg2k files with an application using JasPer, |
| 54 |
possibly leading to the execution of arbitrary code. |
| 55 |
|
| 56 |
Workaround |
| 57 |
========== |
| 58 |
|
| 59 |
There is no known workaround at this time. |
| 60 |
|
| 61 |
Resolution |
| 62 |
========== |
| 63 |
|
| 64 |
All JasPer users should upgrade to the latest version: |
| 65 |
|
| 66 |
# emerge --sync |
| 67 |
# emerge --ask --oneshot --verbose ">=media-libs/jasper-1.900.1-r3" |
| 68 |
|
| 69 |
