Vulnerability Details CVE ID: CVE-2014-0226 Description: The IBM HTTP server is vulnerable to a heap-based buffer overflow, caused by a race condition in the mod_status module when handling the scoreboard. By sending a specially-crafted request, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash. CVSS Base Score: 7.5 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/94678 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:P/A:P) Work around or Mitigations: This can be mitigated by limiting mod_status access to trusted IPs. CVE ID: CVE-2014-0231 Description: The IBM HTTP Server is vulnerable to a denial of service, caused by an error in the mod_cgid module. By sending specially-crafted requests, an attacker could exploit this vulnerability to cause child process to hang. CVSS Base Score: 5.0 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/94674 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P) Work around or Mitigation: This does not affect Windows platform or if you do not have CGI enabled. CVE ID: CVE-2014-0118 Description: The IBM HTTP Server is vulnerable to a denial of service, caused by an error in the mod_deflate module. By sending specially-crafted requests, an attacker could exploit this vulnerability to exhaust all available CPU and memory resources. CVSS Base Score: 5.0 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/94675 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:C) Work around or Mitigation: This can be mitigated by not loading the optional mod_deflate module or by disabling the DEFLATE input filter. CVE ID: CVE-2013-5704 Description: The IBM HTTP Server is vulnerable to HTTP trailers being used to replace HTTP headers late during request processing, potentially confusing modules that examined or modified request headers earlier. CVSS Base Score: 5.0 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/92235 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:P/A:N) Workaround or Mitigation: none The following CVE's do not affect any IBM HTTP Server release CVE ID: CVE-2014-0117 CVE ID: CVE-2014-3523 CVE ID: CVE-2013-4352 Affected Products and Versions This problem affects the IBM HTTP Server component in all editions of WebSphere Application Server and bundling products: * Version 8.5.5 * Version 8.5 * Version 8.0 * Version 7.0 * Version 6.1 * Version 6.0 Remediation/Fixes The recommended solutions is to apply the interim fix, Fix Pack or PTF containing APAR PI22070 for each named product as soon as practical For affected IBM HTTP Server for WebSphere Application Server: For V8.5.0.0 through 8.5.5.2 Full Profile: * Upgrade to Fix Pack 8.5.5.2 and then apply Interim Fix PI22070 - --OR-- * Apply Fix Pack 8.5.5.4 or later (targeted to be available 8 December 2014).
