A double-free flaw in Logsurfer allows a remote attacker to execute arbitrary code.
| Package | Arch | Vulnerable | Unaffected |

Logsurfer is a real time log monitoring and analysis tool.
Logsurfer log files may contain substrings used for executing external commands. The prepare_exec() function in src/exec.c contains a double-free vulnerability.
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.
There is no known workaround at this time.
All Logsurfer users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-admin/logsurfer+-1.8"
