Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
A specially-crafted MIME file (.mim, .uue, .uu, .b64, .bhx, .hqx, and |
| 19 |
.xxe extensions) may cause UUDeview to crash or execute arbitrary code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
UUDeview is a program which is used to transmit binary files over the |
| 25 |
Internet in a text-only format. It is commonly used for email and Usenet |
| 26 |
attachments. It supports multiple encoding formats, including Base64, |
| 27 |
BinHex and UUEncoding. |
| 28 |
|
| 29 |
Description |
| 30 |
=========== |
| 31 |
|
| 32 |
By decoding a MIME archive with excessively long strings for various |
| 33 |
parameters, it is possible to crash UUDeview, or cause it to execute |
| 34 |
arbitrary code. |
| 35 |
|
| 36 |
This vulnerability was originally reported by iDEFENSE as part of a |
| 37 |
WinZip advisory [ Reference: 1 ]. |
| 38 |
|
| 39 |
Impact |
| 40 |
====== |
| 41 |
|
| 42 |
An attacker could create a specially-crafted MIME file and send it via |
| 43 |
email. When recipient decodes the file, UUDeview may execute arbitrary |
| 44 |
code which is embedded in the MIME file, thus granting the attacker |
| 45 |
access to the recipient's account. |
| 46 |
|
| 47 |
Workaround |
| 48 |
========== |
| 49 |
|
| 50 |
All users should upgrade to UUDeview 0.5.20: |
| 51 |
|
| 52 |
~ # emerge sync |
| 53 |
~ # emerge -pv ">=app-text/uudeview-0.5.20" |
| 54 |
~ # emerge ">=app-text/uudeview-0.5.20" |
| 55 |
