Sun(sm) Alert Notification

     * Sun Alert ID: 57628
     * Synopsis: Security Vulnerabilities in the Apache Web Server and
       Apache Modules
     * Category: Security
     * Product: Solaris
     * BugIDs: 5048900, 5069902
     * Avoidance: Patch
     * State: Resolved
     * Date Released: 24-Aug-2004, 12-Oct-2004
     * Date Closed: 12-Oct-2004
     * Date Modified: 09-Sep-2004, 22-Sep-2004, 12-Oct-2004

1. Impact

   A local or remote unprivileged user may be able execute arbitrary code
   on Solaris 8 or Solaris 9 systems running Apache with privileges of
   the Apache HTTP process, due to several security vulnerabilities in
   the Apache Web Server and Apache Web Server modules.

   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.

   These issues are described at the following sites:

   The Change Log for Apache 1.3, at
   [2]http://www.apache.org/dist/httpd/CHANGES_1.3

   CAN-2003-0987: "mod_digest issue" at
   [3]http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0987

   CAN-2003-0020: "filtering of data sent to errorlog" at
   [4]http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0020

   CAN-2004-0174: "possible denial of service" at
   [5]http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0174

   CAN-2003-0993: "mod_access on 64-bit platforms" at
   [6]http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0993

   CAN-2004-0492: "buffer overflow in mod_proxy" at
   [7]http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0492

   Note that Apache 1.3.31 addresses the first four of these five
   security vulnerabilities. Additional changes were made to address
   CAN-2004-0492 in Sun's version of Apache 1.3.31.

2. Contributing Factors

   This issue can occur in the following releases:

   SPARC Platform

     * Solaris 8 without patch [8]116973-01
     * Solaris 9 without patch [9]113146-05

   x86 Platform

     * Solaris 8 without patch [10]116974-01
     * Solaris 9 without patch [11]114145-04

   A system is only vulnerable to this issue if Apache Web Server has
   been configured and is running on the system. The following command
   can be executed to check if the Apache(1M) httpd daemon is running on
   the system:

    $ /usr/bin/ps -ef | grep httpd
      nobody 103892 102307  0   Jan 20 ?        0:27 /usr/apache/bin/httpd


   Apache was not bundled with Solaris prior to Solaris 8. However,
   customers who have built and/or installed a vulnerable version of
   Apache on any version of Solaris are at risk. See the Apache web site
   to download the latest version of Apache which addresses these issues.
   Note also that CAN-2004-0492 is not fixed in a shipped version of
   Apache yet.

   The vulnerabilities CAN-2003-0020, CAN-2004-0174, and CAN-2003-0993
   are present in Apache Web Server versions 1.3 through 1.3.29. The
   vulnerability CAN-2003-098 is present in Apache Web Server versions
   1.3 through 1.3.30.

   The vulnerability CAN-2004-0492 is present in Apache Web Server
   versions 1.3 through 1.3.31. CAN-2004-0492 is addressed in the Apache
   Web Server shipped in the patches described in this Sun Alert.

   In order to determine the version of Apache installed, the following
   command can be executed:

    $ /usr/apache/bin/httpd -v
    Server version: Apache/1.3.27 (Unix)
    Server built:   Nov  1 2002 16:16:41

3. Symptoms

   There are no reliable symptoms that would indicate any of the
   described issues have been exploited to gain unauthorized uid "nobody"
   access to a host.
