Severity: High
Title: Evolution: Integer overflow in camel-lock-helper
Date: January 24, 2005
Bugs: #79183
ID: 200501-35

Synopsis

An overflow in the camel-lock-helper application can be exploited by an
attacker to execute arbitrary code with elevated privileges.

Background

Evolution is a GNOME groupware application similar to Microsoft
Outlook.

Affected packages

-------------------------------------------------------------------
 Package                /  Vulnerable  /                Unaffected
-------------------------------------------------------------------

1 mail-client/evolution <= 2.0.2 >= 2.0.2-r1

Description

Max Vozeler discovered an integer overflow in the camel-lock-helper
application, which is installed as setgid mail by default.

Impact

A local attacker could exploit this vulnerability to execute malicious
code with the privileges of the 'mail' group. A remote attacker could
also setup a malicious POP server to execute arbitrary code when an
Evolution user connects to it.

Workaround

There is no known workaround at this time.

Resolution

All Evolution users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose
# &quot;&gt;=mail-client/evolution-2.0.2-r1&quot;
