It provides a single deployment platform\nfor the JavaServer Pages (JSP) and Java Servlet technologies.\n\nMultiple flaws were found in the way JBoss Web Server handled HTTP DIGEST\nauthentication. These flaws weakened the JBoss Web Server HTTP DIGEST\nauthentication implementation, subjecting it to some of the weaknesses of\nHTTP BASIC authentication, for example, allowing remote attackers to\nperform session replay attacks. (CVE-2011-1184, CVE-2011-5062,\nCVE-2011-5063, CVE-2011-5064)\n\nIt was found that the Java hashCode() method implementation was susceptible\nto predictable hash collisions. A remote attacker could use this flaw to\ncause JBoss Web Server to use an excessive amount of CPU time by sending an\nHTTP request with a large number of parameters whose names map to the same\nhash value. This update introduces a limit on the number of parameters and\nheaders processed per request to mitigate this issue. The default limit is\n512 for parameters and 128 for headers. These defaults can be changed by\nsetting the org.apache.tomcat.util.http.Parameters.MAX_COUNT and\norg.apache.tomcat.util.http.MimeHeaders.MAX_COUNT system properties in\n\"jboss-as/server/[PROFILE]/deploy/properties-service.xml\". (CVE-2011-4858)\n\nA flaw was found in the way JBoss Web Server handled sendfile request\nattributes when using the HTTP APR (Apache Portable Runtime) or NIO\n(Non-Blocking I/O) connector. A malicious web application running on a\nJBoss Web Server instance could use this flaw to bypass security manager\nrestrictions and gain access to files it would otherwise be unable to\naccess, or possibly terminate the Java Virtual Machine (JVM).\n(CVE-2011-2526)\n\nRed Hat would like to thank oCERT for reporting CVE-2011-4858, and the\nApache Tomcat project for reporting CVE-2011-2526. oCERT acknowledges\nJulian W\u00e4lde and Alexander Klink as the original reporters of\nCVE-2011-4858.\n\nWarning: Before applying this update, back up your JBoss Enterprise\nApplication Platform\u0027s \"jboss-as/server/[PROFILE]/deploy/\" directory, along\nwith all other customized configuration files.\n\nAll users of JBoss Enterprise Application Platform 4.3.0 CP10 as provided\nfrom the Red Hat Customer Portal are advised to install this update.",

        "text": "JBoss Web is the web container, based on Apache Tomcat, in JBoss Enterprise\nApplication Platform. It provides a single deployment platform for the\nJavaServer Pages (JSP) and Java Servlet technologies.\n\nA flaw was found in the way JBoss Web handled UTF-8 surrogate pair\ncharacters. If JBoss Web was hosting an application with UTF-8 character\nencoding enabled, or that included user-supplied UTF-8 strings in a\nresponse, a remote attacker could use this flaw to cause a denial of\nservice (infinite loop) on the JBoss Web server. (CVE-2011-4610)\n\nIt was found that the Java hashCode() method implementation was\nsusceptible to predictable hash collisions. A remote attacker could use\nthis flaw to cause JBoss Web to use an excessive amount of CPU time by\nsending an HTTP request with a large number of parameters whose names map\nto the same hash value. This update introduces a limit on the number of\nparameters and headers processed per request to mitigate this issue. The\ndefault limit is 512 for parameters and 128 for headers. These defaults\ncan be changed by setting the\norg.apache.tomcat.util.http.Parameters.MAX_COUNT and\norg.apache.tomcat.util.http.MimeHeaders.MAX_COUNT system properties in\n\"jboss-as/server/[PROFILE]/deploy/properties-service.xml\". (CVE-2011-4858)\n\nIt was found that JBoss Web did not handle large numbers of parameters and\nlarge parameter values efficiently. A remote attacker could make a JBoss\nWeb server use an excessive amount of CPU time by sending an HTTP request\ncontaining a large number of parameters or large parameter values. This\nupdate introduces limits on the number of parameters and headers processed\nper request to address this issue. Refer to the CVE-2011-4858 description\nfor information about the org.apache.tomcat.util.http.Parameters.MAX_COUNT\nand org.apache.tomcat.util.http.MimeHeaders.MAX_COUNT system properties.\n(CVE-2012-0022)\n\nMultiple flaws were found in the way JBoss Web handled HTTP DIGEST\nauthentication. These flaws weakened the JBoss Web HTTP DIGEST\nauthentication implementation, subjecting it to some of the weaknesses of\nHTTP BASIC authentication, for example, allowing remote attackers to\nperform session replay attacks. (CVE-2011-1184, CVE-2011-5062,\nCVE-2011-5063, CVE-2011-5064)\n\nA flaw was found in the way JBoss Web handled sendfile request attributes\nwhen using the HTTP APR (Apache Portable Runtime) or NIO (Non-Blocking I/O)\nconnector. A malicious web application running on a JBoss Web instance\ncould use this flaw to bypass security manager restrictions and gain access\nto files it would otherwise be unable to access, or possibly terminate the\nJava Virtual Machine (JVM). (CVE-2011-2526)\n\nRed Hat would like to thank NTT OSSC for reporting CVE-2011-4610; oCERT for\nreporting CVE-2011-4858; and the Apache Tomcat project for reporting\nCVE-2011-2526. oCERT acknowledges Julian W\u00e4lde and Alexander Klink as the\noriginal reporters of CVE-2011-4858.\n\nWarning: Before applying this update, back up your JBoss Enterprise\nApplication Platform\u0027s \"jboss-as/server/[PROFILE]/deploy/\" directory, along\nwith all other customized configuration files.\n\nUsers of JBoss Enterprise Application Platform 5.1.2 on Red Hat Enterprise\nLinux 4, 5, and 6 should upgrade to these updated packages, which correct\nthese issues. The JBoss server process must be restarted for this update to\ntake effect.",

        "text": "JBoss Web is the web container, based on Apache Tomcat, in JBoss Enterprise\nApplication Platform. It provides a single deployment platform for the\nJavaServer Pages (JSP) and Java Servlet technologies.\n\nA flaw was found in the way JBoss Web handled UTF-8 surrogate pair\ncharacters. If JBoss Web was hosting an application with UTF-8 character\nencoding enabled, or that included user-supplied UTF-8 strings in a\nresponse, a remote attacker could use this flaw to cause a denial of\nservice (infinite loop) on the JBoss Web server. (CVE-2011-4610)\n\nIt was found that the Java hashCode() method implementation was\nsusceptible to predictable hash collisions. A remote attacker could use\nthis flaw to cause JBoss Web to use an excessive amount of CPU time by\nsending an HTTP request with a large number of parameters whose names map\nto the same hash value. This update introduces a limit on the number of\nparameters and headers processed per request to mitigate this issue. The\ndefault limit is 512 for parameters and 128 for headers. These defaults\ncan be changed by setting the\norg.apache.tomcat.util.http.Parameters.MAX_COUNT and\norg.apache.tomcat.util.http.MimeHeaders.MAX_COUNT system properties in\n\"jboss-as/server/[PROFILE]/deploy/properties-service.xml\". (CVE-2011-4858)\n\nIt was found that JBoss Web did not handle large numbers of parameters and\nlarge parameter values efficiently. A remote attacker could make a JBoss\nWeb server use an excessive amount of CPU time by sending an HTTP request\ncontaining a large number of parameters or large parameter values. This\nupdate introduces limits on the number of parameters and headers processed\nper request to address this issue. Refer to the CVE-2011-4858 description\nfor information about the org.apache.tomcat.util.http.Parameters.MAX_COUNT\nand org.apache.tomcat.util.http.MimeHeaders.MAX_COUNT system properties.\n(CVE-2012-0022)\n\nMultiple flaws were found in the way JBoss Web handled HTTP DIGEST\nauthentication. These flaws weakened the JBoss Web HTTP DIGEST\nauthentication implementation, subjecting it to some of the weaknesses of\nHTTP BASIC authentication, for example, allowing remote attackers to\nperform session replay attacks. (CVE-2011-1184, CVE-2011-5062,\nCVE-2011-5063, CVE-2011-5064)\n\nA flaw was found in the way JBoss Web handled sendfile request attributes\nwhen using the HTTP APR (Apache Portable Runtime) or NIO (Non-Blocking I/O)\nconnector. A malicious web application running on a JBoss Web instance\ncould use this flaw to bypass security manager restrictions and gain access\nto files it would otherwise be unable to access, or possibly terminate the\nJava Virtual Machine (JVM). (CVE-2011-2526)\n\nRed Hat would like to thank NTT OSSC for reporting CVE-2011-4610; oCERT for\nreporting CVE-2011-4858; and the Apache Tomcat project for reporting\nCVE-2011-2526. oCERT acknowledges Julian W\u00e4lde and Alexander Klink as the\noriginal reporters of CVE-2011-4858.\n\nWarning: Before applying this update, back up your JBoss Enterprise\nApplication Platform\u0027s \"jboss-as/server/[PROFILE]/deploy/\" directory, along\nwith all other customized configuration files.\n\nAll users of JBoss Enterprise Application Platform 5.1.2 as provided from\nthe Red Hat Customer Portal are advised to install this update.",
