Description:
Secunia has discovered a vulnerability in the Change_passwd plugin for SquirrelMail, which can be exploited by malicious, local users to gain escalated privileges.
The chpasswd utility creates a temporary file insecurely when updating a user's password. This can be exploited via symlink attacks to read the content of "/etc/shadow" or overwrite arbitrary files with "root" privileges.
The vulnerability has been confirmed in version 3.1 of the plugin. Prior versions are likely also affected.
