SYNOPSIS: SunForum is Vulnerable to Issues Described in CERT Advisory
CA-2004-01 Multiple H.323 Message
DETAIL DESCRIPTION:
Sun(sm) Alert Notification
* Sun Alert ID: 57476
* Synopsis: SunForum is Vulnerable to Issues Described in CERT
Advisory CA-2004-01 Multiple H.323 Message
* Category: Security
* Product: SunForum
* BugIDs: 4978924
* Avoidance: Workaround
* State: Committed
* Date Released: 15-Jan-2003
* Date Closed:
* Date Modified:
1. Impact
Unprivileged local and remote users may be able to cause a Denial of
Service (DoS) condition. It may also be possible for a buffer overflow
to occur which may allow an unprivileged local or remote user to
execute arbitrary code.
This issue is described in NISCC Vulnerability Advisory 006489/H323
(see: [1]http://www.uniras.gov.uk/vuls/2004/006489/h323.htm) which is
referenced in CERT Advisory CA-2004-01 (see:
[2]http://www.cert.org/advisories/CA-2004-01.html).
2. Contributing Factors
This issue can occur in the following releases:
SPARC Platform
* SunForum 3.2 (for Solaris 2.6, 7, 8, and 9) or earlier
* SunForum 3D 1.0 (for Solaris 8 and 9)
3. Symptoms
If the described issue occurs, the system may become unresponsive.
SOLUTION SUMMARY:
4. Relief/Workaround
To work around the described issue, ensure all systems that are using
SunForum are behind a firewall or proxy.
System administrators need to ensure that firewalls or proxies are
configured to block H.323 traffic.
Typically, most firewalls are configured to block H.323 traffic as the
firewall can not scope within dynamic port allocation required for the
audio and video streams.
Until this problem is resolved it is advised not to execute SunForum
on a machine that has a direct connection to the Internet.
5. Resolution
A final resolution is pending completion.
