|
CVE Reference:
CAN-2005-0102
(Links to External Site)
|
Date: May 19 2005
|
Impact:
Execution of arbitrary code via local system, Execution of arbitrary code via network, Root access via local system, Root access via network, User access via local system, User access via network
|
Fix Available: Yes Vendor Confirmed: Yes
|
Version(s): 2.0.3 and prior versions

Description:
An integer overflow vulnerability was reported in Evolution in camel-lock-helper. A remote mail server may may be able to execute arbitrary code on a connected system. A local user can execute arbitrary code with elevated privileges.
The flaw resides in 'camel-lock-helper.c', where a user-supplied length value is not properly validated. A user can supply a value of '-1' to cause a zero byte buffer to be allocated and then overflowed. A remote POP3 server can supply a specially crafted response to a connected system to execute arbitrary code on the target system. Also, a local user can invoke Evolution to execute arbitrary code with elevated privileges.
On some systems, this utility is configured with set group id (setgid) 'mail' group privileges and on other systems it is configured with set user id (setuid) 'root' user privileges.
Max Vozeler is credited with discovering this flaw.
|
Impact:
A remote POP3 mail server may be able to execute arbitrary code on the connected system.
A local user can execute arbitrary code on the target system.
The code may run with 'mail' group privileges or 'root' user privileges, depending on the system configuration.

Solution:
Red Hat has released a fix.

Red Hat Security Advisory
Synopsis: Low: evolution security update
Advisory ID: RHSA-2005:238-01
Advisory URL: https://rhn.redhat.com/errata/RHSA-2005-238.html
Issue date: 2005-05-19
Updated on: 2005-05-19
Product: Red Hat Enterprise Linux
CVE Names: CAN-2005-0102
- ---------------------------------------------------------------------
1. Summary:
Updated evolution packages that fix various bugs are now available.
This update has been rated as having low security impact by the Red Hat
Security Response Team.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Desktop version 3 - i386, x86_64
Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64
3. Problem description:
Evolution is the GNOME collection of personal information management (PIM)
tools. Evolution includes a mailer, calendar, contact manager, and
communication facility. The tools which make up Evolution are tightly
integrated with one another and act as a seamless personal information
management tool.
A bug was found in Evolution's helper program camel-lock-helper. This
bug could allow a local attacker to gain root privileges if
camel-lock-helper has been built to execute with elevated privileges. The
Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned
the name CAN-2005-0102 to this issue. On Red Hat Enterprise Linux,
camel-lock-helper is not built to execute with elevated privileges by
default. Please note however that if users have rebuilt Evolution from the
source RPM, as the root user, camel-lock-helper may be given elevated
privileges.
Additionally, these updated packages address the following issues:
- -- If evolution ran during a GNOME session, the evolution-wombat process
did not exit when the user logged out of the desktop.
- -- For folders marked for Offline Synchronization: if a user moved a
message from a Local Folder to an IMAP folder while in
Offline mode, the message was not present in either folder after
returning to Online mode.
This update fixes this problem. Email messages that have been lost
this way may still be present in the following path:
~/evolution/<NAME_OF_MAIL_STORE>/ \
<path-to-folder-via-subfolder-directories>/ \
<temporary-uid-of-message>
If this bug has affected you it may be possible to recover data by
examining the contents of this directory.
All users of evolution should upgrade to these updated packages, which
resolve these issues.
4. Solution:
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied. Use Red Hat
Network to download and update your packages. To launch the Red Hat
