Sun(sm) Alert Notification
* Sun Alert ID: 101841
* Synopsis: Updated Solaris 8 Patches for Apache Security
Vulnerabilities
* Category: Security
* Product: Solaris 8 Operating System
* BugIDs: 6267177
* Avoidance: Patch
* State: Resolved
* Date Released: 10-Aug-2005
* Date Closed: 10-Aug-2005
* Date Modified:
1. Impact
Sun Alerts 57628 and 57496 describe several security vulnerabilities
in the Apache web server and modules. The Solaris 8 patches listed in
these Sun Alerts did not include some of the Apache module files. Thus
several of the vulnerabilities affecting the Apache modules were not
completely addressed. The impact of this is that a local or remote
unprivileged user may be able to execute arbitrary code on systems
running Apache with the privileges of the Apache HTTP process. The
Apache HTTP process normally runs as the unprivileged uid "nobody"
(uid 60001). The ability to execute arbitrary code as the unprivileged
uid "nobody" may lead to modified web content, denial of service, or
further compromise.
The Apache module vulnerabilities affected are as follows:
CAN-2003-0987: "mod_digest issue" at
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0987
CAN-2003-0993: "mod_access on 64-bit platforms" at
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0993
CAN-2004-0492: "buffer overflow in mod_proxy" at
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0492
CAN-2003-0542: "buffer overflows in mod_alias and mod_rewrite" at
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0542
Solaris 8 sites running Apache should install the patches below to
obtain the complete resolution for the Apache module security issues
described in Sun Alerts 57628 and 57496. The Solaris 9 paches listed
in Sun Alerts 57628 and 57496 are the complete resolution for these
issues.
2. Contributing Factors
This issue can occur in the following releases:
SPARC Platform
* Solaris 8 without patch 116973-02
x86 Platform
* Solaris 8 without patch 116974-02
Notes:
1. Solaris 9 is not affected by the issue of some Apache module files
not being included in the patches.
2. Solaris 10 is not affected by these Apache security
vulnerabilities.
3. A system is only vulnerable to this issue if Apache Web Server has
been configured and is running on the system.
To determine if the Apache (1M) httpd daemon is ruuning on the system,
the following command can be run:
$ /usr/bin/ps -ef | grep httpd
nobody 103892 102307 0 Jul 20 ? 0:27 /usr/apache/bin/httpd
3. Symptoms
There are no reliable symptoms that would indicate any of the
described issues have been exploited to execute arbitrary code on a
host as uid 'nobody'. For additional details, see Sun Alert 57628 at
http://sunsolve.sun.com/search/document.do?assetkey=1-26-57628-1.
4. Relief/Workaround
There is no workaround to this issue.
5. Resolution
This issue is addressed in the following releases:
SPARC Platform
* Solaris 8 with patch 116973-02 or later
x86 Platform
* Solaris 8 with patch 116974-02 or later
