Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple vulnerabilities have been discovered in XV, potentially |
| 19 |
resulting in the execution of arbitrary code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
XV is an interactive image manipulation program for the X Window |
| 25 |
System. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |
| 29 |
|

| 31 |
Package / Vulnerable / Unaffected |
| 32 |

| 33 |
1 media-gfx/xv < 3.10a-r11 >= 3.10a-r11 |

Description |
| 36 |
=========== |
| 37 |
|
| 38 |
Greg Roelofs has reported multiple input validation errors in XV image |
| 39 |
decoders. Tavis Ormandy of the Gentoo Linux Security Audit Team has |
| 40 |
reported insufficient validation in the PDS (Planetary Data System) |
| 41 |
image decoder, format string vulnerabilities in the TIFF and PDS |
| 42 |
decoders, and insufficient protection from shell meta-characters in |
| 43 |
malformed filenames. |
| 44 |
|
| 45 |
Impact |
| 46 |
====== |
| 47 |
|
| 48 |
Successful exploitation would require a victim to view a specially |
| 49 |
created image file using XV, potentially resulting in the execution of |
| 50 |
arbitrary code. |
| 51 |
|
| 52 |
Workaround |
| 53 |
========== |
| 54 |
|
| 55 |
There is no known workaround at this time. |
| 56 |
|
| 57 |
Resolution |
| 58 |
========== |
| 59 |
|
| 60 |
All XV users should upgrade to the latest version: |
| 61 |
|
| 62 |
# emerge --sync |
| 63 |
# emerge --ask --oneshot --verbose ">=media-gfx/xv-3.10a-r11" |
| 64 |
|
