20 |
|
21 |
Background |
22 |
========== |

|
24 |
Logsurfer is a real time log monitoring and analysis tool. |
25 |
|
26 |
Affected packages |

Description |
35 |
=========== |
36 |
|
37 |
Logsurfer log files may contain substrings used for executing external |
38 |
commands. The prepare_exec() function in src/exec.c contains a |
39 |
double-free vulnerability. |
40 |
|
41 |
Impact |
42 |
====== |
43 |
|
44 |
A remote attacker could inject specially-crafted strings into a log |
45 |
file processed by Logsurfer, resulting in the execution of arbitrary |
46 |
code with the permissions of the Logsurfer user. |
47 |
|
48 |
Workaround |
49 |
========== |
50 |
|
51 |
There is no known workaround at this time. |
52 |
|
53 |
Resolution |
54 |
========== |
55 |
|
56 |
All Logsurfer users should upgrade to the latest version: |
57 |
|
58 |
# emerge --sync |
59 |
# emerge --ask --oneshot --verbose |
60 |
">=app-admin/logsurfer+-1.8" |
