Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
libxml2 contains multiple buffer overflows which could lead to the |
| 19 |
execution of arbitrary code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
libxml2 is an XML parsing library written in C. |
| 25 |
|
| 26 |
Affected packages |
| 27 |
================= |
| 28 |
|
| 29 |
------------------------------------------------------------------- |
| 30 |
Package / Vulnerable / Unaffected |
| 31 |
------------------------------------------------------------------- |
| 32 |
1 dev-libs/libxml2 < 2.6.15 >= 2.6.15 |
| 33 |
|
| 34 |
Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Multiple buffer overflows have been detected in the nanoftp and |
| 38 |
nanohttp modules. These modules are responsible for parsing URLs with |
| 39 |
ftp information, and resolving names via DNS. |
| 40 |
|
| 41 |
Impact |
| 42 |
====== |
| 43 |
|
| 44 |
An attacker could exploit an application that uses libxml2 by forcing |
| 45 |
it to parse a specially-crafted XML file, potentially causing remote |
| 46 |
execution of arbitrary code. |
| 47 |
|
| 48 |
Workaround |
| 49 |
========== |
| 50 |
|
| 51 |
There is no known workaround at this time. |
| 52 |
|
| 53 |
Resolution |
| 54 |
========== |
| 55 |
|
| 56 |
All libxml2 users should upgrade to the latest version: |
| 57 |
|
| 58 |
# emerge --sync |
| 59 |
# emerge --ask --oneshot --verbose ">=dev-libs/libxml2-2.6.15" |
| 60 |
