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"
