OVERVIEW |
| 15 |
|
| 16 |
GV can be tricked into executing arbitary shell commands. |
| 17 |
|
| 18 |
DETAIL |
| 19 |
|
| 20 |
When GV detects that the document is either a PDF file or a |
| 21 |
GZip compressed file, it executes some commands with the help |
| 22 |
of the system() function. Unfortunately, these commands |
| 23 |
contain the filename, which can be considered as untrusted user |
| 24 |
input. It is then possible to distribute a file (with a meticulously |
| 25 |
choosed filename, that can even seems innocent) that causes execution of |
| 26 |
arbitrary shell commands when it is read with GV. |

SOLUTION |
| 32 |
|
| 33 |
It is recommended that all Gentoo Linux users who are running |
| 34 |
app-text/gv-3.58-r1 and earlier update their systems |
| 35 |
as follows: |
| 36 |
|
| 37 |
emerge rsync |
| 38 |
emerge gv |
| 39 |
emerge clean |
