Background |
23 |
========== |

Description |
40 |
=========== |
41 |
|
42 |
Ulf Harnhammar reported a possible buffer overflow in the handling of |
43 |
TFTP URLs in libcurl due to the lack of boundary checks. |
44 |
|
45 |
Impact |
46 |
====== |
47 |
|
48 |
An attacker could exploit this vulnerability to compromise a user's |
49 |
system by enticing the user to request a malicious URL with |
50 |
cURL/libcurl or to use a HTTP server redirecting to a malicious TFTP |
51 |
URL. |
52 |
|
53 |
Workaround |
54 |
========== |
55 |
|
56 |
There is no known workaround at this time. |
57 |
|
58 |
Resolution |
59 |
========== |
60 |
|
61 |
All cURL users should upgrade to the latest version: |
62 |
|
63 |
# emerge --sync |
64 |
# emerge --ask --oneshot --verbose ">=net-misc/curl-7.15.1-r1" |
