|
CVE Reference:
CVE-2005-2933
(Links to External Site)
|
Date: Dec 8 2005
|
Impact:
Execution of arbitrary code via network, User access via network
|
Fix Available: Yes Vendor Confirmed: Yes
|
Version(s): imap-2004c1
|
Description:
iDEFENSE reported a vulnerability in UW-IMAP. A remote authenticated user can execute arbitrary code on the target system.
The mail_valid_net_parse_work() function in 'src/c-client/mail.c' does not properly validate the user-supplied mailbox name. A remote authenticated user can supply a mailbox name value that contains a single quote character ('"') along with other specially crafted values to trigger a stack overflow and execute arbitrary code.
The code will run with the privileges of the IMAP service.
Anonymous IMAP users cannot trigger the overflow.
The vendor was notified on September 15, 2005.
infamous41md@hotpop.com discovered this vulnerability.
The original advisory is available at:

|
Impact:
A remote authenticated user can execute arbitrary code on the target system with the privileges of the target service.

Solution:
Red Hat has released a fix.

Red Hat Security Advisory
Synopsis: Moderate: imap security update
Advisory ID: RHSA-2005:850-01
Advisory URL: https://rhn.redhat.com/errata/RHSA-2005-850.html
Issue date: 2005-12-06
Updated on: 2005-12-06
Product: Red Hat Enterprise Linux
CVE Names: CVE-2005-2933
- ---------------------------------------------------------------------
1. Summary:
An updated imap package that fixes a buffer overflow issue is now available.
This update has been rated as having moderate security impact by the Red
Hat Security Response Team.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64
Red Hat Linux Advanced Workstation 2.1 - ia64
Red Hat Enterprise Linux ES version 2.1 - i386
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:
The imap package provides server daemons for both the IMAP (Internet
Message Access Protocol) and POP (Post Office Protocol) mail access protocols.
A buffer overflow flaw was discovered in the way the c-client library
parses user supplied mailboxes. If an authenticated user requests a
specially crafted mailbox name, it may be possible to execute arbitrary
code on a server that uses the library. The Common Vulnerabilities and
Exposures project has assigned the name CVE-2005-2933 to this issue.
All users of imap should upgrade to these updated packages, which contain a
backported patch and are not vulnerable to this issue.
4. Solution:
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
This update is available via Red Hat Network. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:
up2date
This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
