Title: Openswan: Insecure temporary file creation (GLSA 200903-18)
Severity: normal
Exploitable: local
Date: March 09, 2009
Bug(s): #238574
ID: 200903-18

Synopsis

An insecure temporary file usage has been reported in Openswan, allowing for symlink attacks.

Background

Openswan is an implementation of IPsec for Linux.

Affected Packages

Package: net-misc/openswan
Vulnerable: < 2.4.13-r2
Unaffected: >= 2.4.13-r2
Architectures: All supported architectures


Description

Dmitry E. Oboukhov reported that the IPSEC livetest tool does not handle the ipseclive.conn and ipsec.olts.remote.log temporary files securely.

Impact

A local attacker could perform symlink attacks to execute arbitrary code and overwrite arbitrary files with the privileges of the user running the application.

Workaround

There is no known workaround at this time.

Resolution

All Openswan users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/openswan-2.4.13-r2"
