Multiple vulnerabilities have been identified in Smb4K. |

Background |

Description |
| 34 |
=========== |
| 35 |
|
| 36 |
Kees Cook of the Ubuntu Security Team has identified multiple |
| 37 |
vulnerabilities in Smb4K. |
| 38 |
|
| 39 |
* The writeFile() function of smb4k/core/smb4kfileio.cpp makes |
| 40 |
insecure usage of temporary files. |
| 41 |
|
| 42 |
* The writeFile() function also stores the contents of the sudoers |
| 43 |
file with incorrect permissions, allowing for the file's contents to |
| 44 |
be world-readable. |
| 45 |
|
| 46 |
* The createLockFile() and removeLockFile() functions improperly |
| 47 |
handle lock files, possibly allowing for a race condition in file |
| 48 |
handling. |
| 49 |
|
| 50 |
* The smb4k_kill utility distributed with Smb4K allows any user in |
| 51 |
the sudoers group to kill any process on the system. |
| 52 |
|
| 53 |
* Lastly, there is the potential for multiple stack overflows when |
| 54 |
any Smb4K utility is used with the sudo command. |

Impact |
| 57 |
====== |
| 58 |
|
| 59 |
A local attacker could gain unauthorized access to arbitrary files via |
| 60 |
numerous attack vectors. In some cases to obtain this unauthorized |
| 61 |
access, an attacker would have to be a member of the sudoers list. |
| 62 |
|
| 63 |
Workaround |
| 64 |
========== |
| 65 |
|
| 66 |
There is no known workaround at this time. |
| 67 |
|
| 68 |
Resolution |
| 69 |
========== |
| 70 |
|
| 71 |
All Smb4K users should upgrade to the latest version: |
| 72 |
|
| 73 |
# emerge --sync |
| 74 |
# emerge --ask --oneshot --verbose ">=net-misc/smb4k-0.6.10a" |
| 75 |
|
