Gentoo Linux Security Advisory

Title: Logsurfer: Arbitrary code execution (GLSA 201201-04)
Severity: normal
Exploitable: remote
Date: January 20, 2012
Bug(s): #387397
ID: 201201-04

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: app-admin/logsurfer+
Vulnerable: < 1.8
Unaffected: >= 1.8
Architectures: All supported architectures


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


References


CVE-2011-3626
