CVE-2009-3560 4 Apache, Libexpat Project, Redhat and 1 more 6 Http Server, Libexpat, Enterprise Linux and 3 more 2026-04-23 N/A
The big2_toUtf8 function in lib/xmltok.c in libexpat in Expat 2.0.1, as used in the XML-Twig module for Perl, allows context-dependent attackers to cause a denial of service (application crash) via an XML document with malformed UTF-8 sequences that trigger a buffer over-read, related to the doProlog function in lib/xmlparse.c, a different vulnerability than CVE-2009-2625 and CVE-2009-3720.
CVE-2008-0005 4 Apache, Canonical, Fedoraproject and 1 more 6 Http Server, Ubuntu Linux, Fedora and 3 more 2026-04-23 N/A
mod_proxy_ftp in Apache 2.2.x before 2.2.7-dev, 2.0.x before 2.0.62-dev, and 1.3.x before 1.3.40-dev does not define a charset, which allows remote attackers to conduct cross-site scripting (XSS) attacks using UTF-7 encoding.
CVE-2007-3847 4 Apache, Canonical, Fedoraproject and 1 more 7 Http Server, Ubuntu Linux, Fedora and 4 more 2026-04-23 N/A
The date handling code in modules/proxy/proxy_util.c (mod_proxy) in Apache 2.3.0, when using a threaded MPM, allows remote origin servers to cause a denial of service (caching forward proxy process crash) via crafted date headers that trigger a buffer over-read.
CVE-2007-1862 1 Apache 1 Http Server 2026-04-23 N/A
The recall_headers function in mod_mem_cache in Apache 2.2.4 does not properly copy all levels of header data, which can cause Apache to return HTTP headers containing previously used data, which could be used by remote attackers to obtain potentially sensitive information.
CVE-2007-3304 4 Apache, Canonical, Fedoraproject and 1 more 11 Http Server, Ubuntu Linux, Fedora and 8 more 2026-04-23 N/A
Apache httpd 1.3.37, 2.0.59, and 2.2.4 with the Prefork MPM module, allows local users to cause a denial of service by modifying the worker_score and process_score arrays to reference an arbitrary process ID, which is sent a SIGUSR1 signal from the master process, aka "SIGUSR1 killer."
CVE-2007-3303 1 Apache 1 Http Server 2026-04-23 N/A
Apache httpd 2.0.59 and 2.2.4, with the Prefork MPM module, allows local users to cause a denial of service via certain code sequences executed in a worker process that (1) stop request processing by killing all worker processes and preventing creation of replacements or (2) hang the system by forcing the master process to fork an arbitrarily large number of worker processes. NOTE: This might be an inherent design limitation of Apache with respect to worker processes in hosted environments.
CVE-2007-0450 2 Apache, Redhat 8 Http Server, Tomcat, Certificate System and 5 more 2026-04-23 N/A
Directory traversal vulnerability in Apache HTTP Server and Tomcat 5.x before 5.5.22 and 6.x before 6.0.10, when using certain proxy modules (mod_proxy, mod_rewrite, mod_jk), allows remote attackers to read arbitrary files via a .. (dot dot) sequence with combinations of (1) "/" (slash), (2) "\" (backslash), and (3) URL-encoded backslash (%5C) characters in the URL, which are valid separators in Tomcat but not in Apache.
CVE-2009-1195 2 Apache, Redhat 3 Http Server, Enterprise Linux, Jboss Enterprise Web Server 2026-04-23 N/A
The Apache HTTP Server 2.2.11 and earlier 2.2 versions does not properly handle Options=IncludesNOEXEC in the AllowOverride directive, which allows local users to gain privileges by configuring (1) Options Includes, (2) Options +Includes, or (3) Options +IncludesNOEXEC in a .htaccess file, and then inserting an exec element in a .shtml file.
CVE-2007-1863 3 Apache, Apple, Redhat 5 Http Server, Mac Os X Server, Certificate System and 2 more 2026-04-23 N/A
cache_util.c in the mod_cache module in Apache HTTP Server (httpd), when caching is enabled and a threaded Multi-Processing Module (MPM) is used, allows remote attackers to cause a denial of service (child processing handler crash) via a request with the (1) s-maxage, (2) max-age, (3) min-fresh, or (4) max-stale Cache-Control headers without a value.
CVE-2007-4465 2 Apache, Redhat 6 Http Server, Certificate System, Enterprise Linux and 3 more 2026-04-23 6.1 Medium
Cross-site scripting (XSS) vulnerability in mod_autoindex.c in the Apache HTTP Server before 2.2.6, when the charset on a server-generated page is not defined, allows remote attackers to inject arbitrary web script or HTML via the P parameter using the UTF-7 charset. NOTE: it could be argued that this issue is due to a design limitation of browsers that attempt to perform automatic content type detection.
CVE-2007-6203 1 Apache 1 Http Server 2026-04-23 N/A
Apache HTTP Server 2.0.x and 2.2.x does not sanitize the HTTP Method specifier header from an HTTP request when it is reflected back in a "413 Request Entity Too Large" error message, which might allow cross-site scripting (XSS) style attacks using web client components that can send arbitrary headers in requests, as demonstrated via an HTTP request containing an invalid Content-length value, a similar issue to CVE-2006-3918.
CVE-2007-6388 2 Apache, Redhat 6 Http Server, Certificate System, Enterprise Linux and 3 more 2026-04-23 N/A
Cross-site scripting (XSS) vulnerability in mod_status in the Apache HTTP Server 2.2.0 through 2.2.6, 2.0.35 through 2.0.61, and 1.3.2 through 1.3.39, when the server-status page is enabled, allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.
