Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
ProZilla contains several buffer overflow vulnerabilities that can be |
| 19 |
exploited by a malicious server to execute arbitrary code with the |
| 20 |
rights of the user running ProZilla. |
| 21 |
|
| 22 |
Background |
| 23 |
========== |
| 24 |
|
| 25 |
ProZilla is a download accelerator for Linux. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |
| 29 |
|
| 30 |
------------------------------------------------------------------- |
| 31 |
Package / Vulnerable / Unaffected |
| 32 |
------------------------------------------------------------------- |
| 33 |
1 www-client/prozilla <= 1.3.6-r2 Vulnerable! |
| 34 |
------------------------------------------------------------------- |
| 35 |
NOTE: Certain packages are still vulnerable. Users should migrate |
| 36 |
to another package if one is available or wait for the |
| 37 |
existing packages to be marked stable by their |
| 38 |
architecture maintainers. |

Description |
| 41 |
=========== |
| 42 |
|
| 43 |
ProZilla contains several exploitable buffer overflows in the code |
| 44 |
handling the network protocols. |
| 45 |
|
| 46 |
Impact |
| 47 |
====== |
| 48 |
|
| 49 |
A remote attacker could setup a malicious server and entice a user to |
| 50 |
retrieve files from that server using ProZilla. This could lead to the |
| 51 |
execution of arbitrary code with the rights of the user running |
| 52 |
ProZilla. |
| 53 |
|
| 54 |
Workaround |
| 55 |
========== |
| 56 |
|
| 57 |
There is no known workaround at this time. |
| 58 |
|
| 59 |
Resolution |
| 60 |
========== |
| 61 |
|
| 62 |
Currently, there is no released version of ProZilla that contains a fix |
| 63 |
for these issues. The original author did not respond to our queries, |
| 64 |
the code contains several other problems and more secure alternatives |
| 65 |
exist. Therefore, the ProZilla package has been hard-masked prior to |
| 66 |
complete removal from Portage, and current users are advised to unmerge |
| 67 |
the package. |
