Synopsis
========
A double-free flaw in Logsurfer allows a remote attacker to execute
arbitrary code.

Background
==========
Logsurfer is a real time log monitoring and analysis tool.

Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-admin/logsurfer+ < 1.8 >== 1.8

Description
===========
Logsurfer log files may contain substrings used for executing external
commands. The prepare_exec() function in src/exec.c contains a
double-free vulnerability.

Impact
======
A remote attacker could inject specially-crafted strings into a log
file processed by Logsurfer, resulting in the execution of arbitrary
code with the permissions of the Logsurfer user.

Workaround
==========
There is no known workaround at this time.

Resolution
==========
All Logsurfer users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose
">=app-admin/logsurfer+-1.8"

References
