Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Tar is vulnerable to directory traversal possibly allowing for the |
| 19 |
overwriting of arbitrary files. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
The Tar program provides the ability to create and manipulate tar |
| 25 |
archives. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |
| 29 |
|
| 30 |
------------------------------------------------------------------- |
| 31 |
Package / Vulnerable / Unaffected |
| 32 |
------------------------------------------------------------------- |
| 33 |
1 app-arch/tar < 1.16-r2 >= 1.16-r2 |
| 34 |
|
| 35 |
Description |
| 36 |
=========== |
| 37 |
|
| 38 |
Tar does not properly extract archive elements using the GNUTYPE_NAMES |
| 39 |
record name, allowing files to be created at arbitrary locations using |
| 40 |
symlinks. Once a symlink is extracted, files after the symlink in the |
| 41 |
archive will be extracted to the destination of the symlink. |
| 42 |
|
| 43 |
Impact |
| 44 |
====== |
| 45 |
|
| 46 |
An attacker could entice a user to extract a specially crafted tar |
| 47 |
archive, possibly allowing for the overwriting of arbitrary files on |
| 48 |
the system extracting the archive. |
| 49 |
|
| 50 |
Workaround |
| 51 |
========== |
| 52 |
|
| 53 |
There is no known workaround at this time. |
| 54 |
|
| 55 |
Resolution |
| 56 |
========== |
| 57 |
|
| 58 |
All Tar users should upgrade to the latest version: |
| 59 |
|
| 60 |
# emerge --sync |
| 61 |
# emerge --ask --oneshot --verbose ">=app-arch/tar-1.16-r2" |
| 62 |
|
| 63 |
