Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
A vulnerability in cURL may allow for arbitrary file access. |
| 19 |
|
| 20 |
Background |
| 21 |
========== |
| 22 |
|
| 23 |
cURL is a command line tool for transferring files with URL syntax, |
| 24 |
supporting numerous protocols. |
| 25 |
|
| 26 |
Affected packages |
| 27 |
================= |
| 28 |
|
| 29 |
------------------------------------------------------------------- |
| 30 |
Package / Vulnerable / Unaffected |
| 31 |
------------------------------------------------------------------- |
| 32 |
1 net-misc/curl < 7.19.4 >= 7.19.4 |
| 33 |
|
| 34 |
Description |
| 35 |
=========== |
| 36 |
|
| 37 |
David Kierznowski reported that the redirect implementation accepts |
| 38 |
arbitrary Location values when CURLOPT_FOLLOWLOCATION is enabled. |
| 39 |
|
| 40 |
Impact |
| 41 |
====== |
| 42 |
|
| 43 |
A remote attacker could possibly exploit this vulnerability to make |
| 44 |
remote HTTP servers trigger arbitrary requests to intranet servers and |
| 45 |
read or overwrite arbitrary files via a redirect to a file: URL, or, if |
| 46 |
the libssh2 USE flag is enabled, execute arbitrary commands via a |
| 47 |
redirect to an scp: URL. |
| 48 |
|
| 49 |
Workaround |
| 50 |
========== |
| 51 |
|
| 52 |
There is no known workaround at this time. |
| 53 |
|
| 54 |
Resolution |
| 55 |
========== |
| 56 |
|
| 57 |
All cURL users should upgrade to the latest version: |
| 58 |
|
| 59 |
# emerge --sync |
| 60 |
# emerge --ask --oneshot --verbose ">=net-misc/curl-7.19.4" |
| 61 |
