TITLE:
IPCop Squid Vulnerability and Web Backup Security Issue

SECUNIA ADVISORY ID:
SA17513

VERIFY ADVISORY:
http://secunia.com/advisories/17513/

CRITICAL:
Less critical

IMPACT:
Exposure of sensitive information, DoS

WHERE:
>From remote

OPERATING SYSTEM:
IPCop 1.4.x
http://secunia.com/product/5028/

DESCRIPTION:
A vulnerability and a security issue have been reported in IPCop,
which can be exploited by malicious people to cause a DoS (Denial of
Service), and by malicious, local users to gain access to potentially
sensitive information.

1) A vulnerability in Squid may be exploited by malicious people to
cause a DoS.

For more information:
SA17271

2) The key used to encrypt web backup files is stored in
"/var/ipcop/backup/" and is world-readable. This can potentially be
exploited by malicious users to decrypt backup files, or by the
"nobody" user to overwrite arbitrary files by creating malicious
backup files and restoring them.

A race condition that can potentially allow the "nobody" user to
replace the backup file before it is encrypted has also been fixed.

SOLUTION:
Update to version 1.4.10.
