Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Net-SNMP creates temporary files in an insecure manner, possibly |
| 19 |
allowing the execution of arbitrary code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
Net-SNMP is a suite of applications used to implement the Simple |
| 25 |
Network Management Protocol. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |
| 29 |
|
| 30 |
------------------------------------------------------------------- |
| 31 |
Package / Vulnerable / Unaffected |
| 32 |
------------------------------------------------------------------- |
| 33 |
1 net-analyzer/net-snmp < 5.2.1-r1 >= 5.2.1-r1 |

Description |
| 36 |
=========== |
| 37 |
|
| 38 |
The fixproc application of Net-SNMP creates temporary files with |
| 39 |
predictable filenames. |
| 40 |
|
| 41 |
Impact |
| 42 |
====== |
| 43 |
|
| 44 |
A malicious local attacker could exploit a race condition to change the |
| 45 |
content of the temporary files before they are executed by fixproc, |
| 46 |
possibly leading to the execution of arbitrary code. A local attacker |
| 47 |
could also create symbolic links in the temporary files directory, |
| 48 |
pointing to a valid file somewhere on the filesystem. When fixproc is |
| 49 |
executed, this would result in the file being overwritten. |
| 50 |
|
| 51 |
Workaround |
| 52 |
========== |
| 53 |
|
| 54 |
There is no known workaround at this time. |
| 55 |
|
| 56 |
Resolution |
| 57 |
========== |
| 58 |
|
| 59 |
All Net-SNMP users should upgrade to the latest available version: |
| 60 |
|
| 61 |
# emerge --sync |
| 62 |
# emerge --ask --oneshot --verbose ">=net-analyzer/net-snmp-5.2.1-r1" |
| 63 |
|
| 64 |
