The Kerberos/MapReduce security functionality in Apache Hadoop 0.20.203.0 through 0.20.205.0, 0.23.x before 0.23.2, and 1.0.x before 1.0.2, as used in Cloudera CDH CDH3u0 through CDH3u2, Cloudera hadoop-0.20-sbin before 0.20.2+923.197, and other products, allows remote authenticated users to impersonate arbitrary cluster user accounts via unspecified vectors.
Apache Traffic Server 2.0.x and 3.0.x before 3.0.4 and 3.1.x before 3.1.3 does not properly allocate heap memory, which allows remote attackers to cause a denial of service (daemon crash) via a long HTTP Host header.
Cross-site scripting (XSS) vulnerability in Apache Wicket 1.4.x before 1.4.20 allows remote attackers to inject arbitrary web script or HTML via the wicket:pageMapName parameter.
Directory traversal vulnerability in Apache Wicket 1.4.x before 1.4.20 and 1.5.x before 1.5.5 allows remote attackers to read arbitrary web-application files via a relative pathname in a URL for a Wicket resource that corresponds to a null package.
fcgid_spawn_ctl.c in the mod_fcgid module 2.3.6 for the Apache HTTP Server does not recognize the FcgidMaxProcessesPerClass directive for a virtual host, which makes it easier for remote attackers to cause a denial of service (memory consumption) via a series of HTTP requests that triggers a process count higher than the intended limit.
Apache Struts 2 before 2.2.3.1 evaluates a string as an OGNL expression during the handling of a conversion error, which allows remote attackers to modify run-time data values, and consequently execute arbitrary code, via invalid input to a field.
tables/apr_hash.c in the Apache Portable Runtime (APR) library through 1.4.5 computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted input to an application that maintains a hash table.
Multiple cross-site scripting (XSS) vulnerabilities in Apache Struts 2.0.14 and 2.2.3 allow remote attackers to inject arbitrary web script or HTML via the (1) name or (2) lastName parameter to struts2-showcase/person/editPerson.action, or the (3) clientName parameter to struts2-rest-showcase/orders.
Multiple cross-site scripting (XSS) vulnerabilities in Apache Struts 1.3.10 allow remote attackers to inject arbitrary web script or HTML via (1) the name parameter to struts-examples/upload/upload-submit.do, or the message parameter to (2) struts-cookbook/processSimple.do or (3) struts-cookbook/processDyna.do.
The log_cookie function in mod_log_config.c in the mod_log_config module in the Apache HTTP Server 2.2.17 through 2.2.21, when a threaded MPM is used, does not properly handle a %{}C format string, which allows remote attackers to cause a denial of service (daemon crash) via a cookie that lacks both a name and a value.
