-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2009.0064 -- [Solaris] Security vulnerability in Solaris Related to the Apache 1.3 mod_perl(3) Module Component "PerlRun.pm" may Lead to Denial of Service (DoS) 3 September 2009 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: mod_perl Publisher: Sun Microsystems Operating System: Solaris Impact: Denial of Service Access: Remote/Unauthenticated CVE Names: CVE-2007-1349 Ref: ESB-2007.0417 Original Bulletin: http://sunsolve.sun.com/search/printfriendly.do?assetkey=1-66-248386-1 Revision History: September 3 2009: Patches released for Solaris 8 July 14 2009: Updated Contributing Factors and Resolution sections January 16 2009: Initial Release - --------------------------BEGIN INCLUDED TEXT-------------------- Solution Type: Sun Alert Solution 248386 : Security vulnerability in Solaris Related to the Apache 1.3 mod_perl(3) Module Component "PerlRun.pm" may Lead to Denial of Service (DoS) Bug ID: 6738158 Product: Solaris 8 Operating System Solaris 9 Operating System Solaris 10 Operating System Date of Workaround Release: 14-Jan-2009 Date of Resolved Release: 24-Aug-2009 SA Document Body Security vulnerability in Solaris related to the Apache 1.3 mod_perl(3) module component "PerlRun.pm" may lead to Denial of Service (DoS): 1. Impact A security vulnerability in Solaris related to the Apache HTTP server may affect the Apache 1.3 web server bundled with Solaris 8, 9 and 10 . The vulnerability, a Denial of Service(DoS) in the "RunPerl.pm" component of the mod_perl(3) Apache server module, may allow a remote unprivileged user to cause a Denial of Service to the Apache "httpd" process. Additional information regarding this issue is available at: * CVE-2007-1349 at: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-1349 2. Contributing Factors This issue can occur in the following releases: SPARC Platform * Solaris 8 without patch 116973-08 * Solaris 9 without patch 113146-12 * Solaris 10 without patch 122911-14 * OpenSolaris based upon builds snv_01 through snv_99 x86 Platform * Solaris 8 without patch 116974-08 * Solaris 9 without patch 114145-11 * Solaris 10 without patch 122912-14 * OpenSolaris based upon builds snv_01 through snv_99 Note 1: OpenSolaris distributions may include additional bug fixes above and beyond the build from which it was derived. To determine the base build of OpenSolaris, the following command can be used: $ uname -v snv_86 Note 2: A system is only vulnerable to this issue if the Apache 1.3 web server has been configured and is running on the system. To determine if the Apache 1.3 web server is running on the system, the following command can be used: $ /usr/bin/ps -ef | grep "/usr/apache/bin/http" nobody 103892 102307 0 Jan 20 ? 0:27 /usr/apache/bin/httpd Note 3: This vulnerability only affects systems which make use of the Apache Server mod_perl(3) (PerlRun.pm) component. To determine if the "PerlRun.pm" component is used, a command such as the following can be run for all configuration files that define the running Apache 1.3 configuration: $ grep PerlHandler /etc/apache/httpd.conf | grep Apache::PerlRun PerlHandler Apache::PerlRun Note 4: Solaris 8 entered EOSL Phase 2 on 1 April 2009. Entitlement to patches developed on or after 1 April 2009 requires the purchase of the Solaris 8 Vintage Patch Service. See note in section 5 for more details. 3. Symptoms If the issue is exploited, the Apache 1.3 web server may be unresponsive, possibly consuming all available CPU resources. Commands such as prstat(1M) can be used to determine the utilization of system resources: $ prstat -s cpu [...] 4. Workaround To work around the described issue, make sure that the mod_perl(3) (PerlRun.pm) component is not configured in the Apache 1.3 "httpd.conf" file. 5. Resolution This issue is addressed in the following releases: SPARC Platform * Solaris 8 with patch 116973-08 or later * Solaris 9 with patch 113146-12 or later * Solaris 10 with patch 122911-14 or later * OpenSolaris based upon build snv_100 or later x86 Platform * Solaris 8 with patch 116974-08 or later * Solaris 9 with patch 114145-11 or later * Solaris 10 with patch 122912-14 or later * OpenSolaris based upon build snv_100 or later Note: The READMEs of Solaris 8 patches developed on or after 1 April 2009 are available to all customers. However, Solaris 8 entered EOSL Phase 2 on April 1, 2009 and thus entitlement for these patches, including those that fix security vulnerabilities, requires the purchase of the Solaris 8 Vintage Patch Service.
