TITLE:
Gfax Insecure Temporary Files Privileges Escalation Security Issue

SECUNIA ADVISORY ID:
SA25937

VERIFY ADVISORY:
http://secunia.com/advisories/25937/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

SOFTWARE:
Gfax 0.x
http://secunia.com/product/14726/

DESCRIPTION:
Steve Kemp has reported a security issue in Gfax, which can be
exploited by malicious, local users to gain escalated privileges.

The security issue is caused due to the "delete_crontab_entry()"
function in src/mgett_setup.c handling temporary files in an insecure
manner. This can be exploited to execute arbitrary commands with
escalated privileges (usually root user).

The security issue is reported in version 0.4.2. Other versions may
also be affected.

SOLUTION:
Update to version 0.7.6.
