Synopsis |
| 17 |
======== |
| 18 |
|
| 19 |
There are multiple format string vulnerabilities in the neon library |
| 20 |
used in cadaver, possibly leading to execution of arbitrary code when |
| 21 |
connected to a malicious server. |
| 22 |
|
| 23 |
Background |
| 24 |
========== |
| 25 |
|
| 26 |
According to http://www.webdav.org/cadaver, cadaver is a command-line |
| 27 |
WebDAV client for Unix. It supports file upload, download, on-screen |
| 28 |
display, namespace operations (move/copy), collection creation and |
| 29 |
deletion, and locking operations. |
| 30 |
|
| 31 |
Affected packages |
| 32 |
================= |
| 33 |
|
| 34 |
------------------------------------------------------------------- |
| 35 |
Package / Vulnerable / Unaffected |
| 36 |
------------------------------------------------------------------- |
| 37 |
net-misc/cadaver < 0.22.1 >= 0.22.1 |
| 38 |
|
| 39 |
Description |
| 40 |
=========== |
| 41 |
|
| 42 |
Cadaver code includes the neon library, which in versions 0.24.4 and |
| 43 |
previous is vulnerable to multiple format string attacks. The latest |
| 44 |
version of cadaver uses version 0.24.5 of the neon library, which makes |
| 45 |
it immune to this vulnerability. |
| 46 |
|
| 47 |
Impact |
| 48 |
====== |
| 49 |
|
| 50 |
When using cadaver to connect to an untrusted WebDAV server, this |
| 51 |
vulnerability can allow a malicious remote server to execute arbitrary |
| 52 |
code on the client with the rights of the user using cadaver. |
| 53 |
|
| 54 |
Workaround |
| 55 |
========== |
| 56 |
|
| 57 |
A workaround is not currently known for this issue. All users are |
| 58 |
advised to upgrade to the latest version of the affected package. |
| 59 |
|
| 60 |
Resolution |
| 61 |
========== |
| 62 |
|
| 63 |
cadaver users should upgrade to version 0.22.1 or later: |
| 64 |
|
| 65 |
# emerge sync |
| 66 |
|
| 67 |
# emerge -pv ">=net-misc/cadaver-0.22.1" |
| 68 |
# emerge ">=net-misc/cadaver-0.22.1" |
| 69 |
