1 CVE-2011-5034 20 DoS 2011-12-29 2012-11-06
7.8
None Remote Low Not required None None Complete
Apache Geronimo 2.2.1 and earlier computes hash values for form parameters without restricting the ability to trigger hash collisions predictably, which allows remote attackers to cause a denial of service (CPU consumption) by sending many crafted parameters. NOTE: this might overlap CVE-2011-4461.
2 CVE-2011-4415 20 DoS 2011-11-08 2012-07-03
1.2
None Local High Not required None None Partial
The ap_pregsub function in server/util.c in the Apache HTTP Server 2.0.x through 2.0.64 and 2.2.x through 2.2.21, when the mod_setenvif module is enabled, does not restrict the size of values of environment variables, which allows local users to cause a denial of service (memory consumption or NULL pointer dereference) via a .htaccess file with a crafted SetEnvIf directive, in conjunction with a crafted HTTP request header, related to (1) the "len +=" statement and (2) the apr_pcalloc function call, a different vulnerability than CVE-2011-3607.
3 CVE-2011-3348 399 DoS 2011-09-20 2017-09-18
4.3
None Remote Medium Not required None None Partial
The mod_proxy_ajp module in the Apache HTTP Server before 2.2.21, when used with mod_proxy_balancer in certain configurations, allows remote attackers to cause a denial of service (temporary "error state" in the backend server) via a malformed HTTP request.
4 CVE-2011-3192 399 1 DoS 2011-08-29 2017-09-18
7.8
None Remote Low Not required None None Complete
The byterange filter in the Apache HTTP Server 1.3.x, 2.0.x through 2.0.64, and 2.2.x through 2.2.19 allows remote attackers to cause a denial of service (memory and CPU consumption) via a Range header that expresses multiple overlapping ranges, as exploited in the wild in August 2011, a different vulnerability than CVE-2007-0086.
5 CVE-2011-2526 20 DoS Bypass 2011-07-14 2017-09-18
4.4
None Local Medium Not required Partial Partial Partial
Apache Tomcat 5.5.x before 5.5.34, 6.x before 6.0.33, and 7.x before 7.0.19, when sendfile is enabled for the HTTP APR or HTTP NIO connector, does not validate certain request attributes, which allows local users to bypass intended file access restrictions or cause a denial of service (infinite loop or JVM crash) by leveraging an untrusted web application.
6 CVE-2011-2516 189 DoS Overflow 2011-07-11 2017-08-28
5.0
None Remote Low Not required None None Partial
Off-by-one error in the XML signature feature in Apache XML Security for C++ 1.6.0, as used in Shibboleth before 2.4.3 and possibly other products, allows remote attackers to cause a denial of service (crash) via a signature using a large RSA key, which triggers a buffer overflow.
7 CVE-2011-1928 399 DoS 2011-05-24 2012-10-29
4.3
None Remote Medium Not required None None Partial
The fnmatch implementation in apr_fnmatch.c in the Apache Portable Runtime (APR) library 1.4.3 and 1.4.4, and the Apache HTTP Server 2.2.18, allows remote attackers to cause a denial of service (infinite loop) via a URI that does not match unspecified types of wildcard patterns, as demonstrated by attacks against mod_autoindex in httpd when a /*/WEB-INF/ configuration pattern is used. NOTE: this issue exists because of an incorrect fix for CVE-2011-0419.
8 CVE-2011-1783 399 DoS 2011-06-06 2017-09-18
4.3
None Remote Medium Not required None None Partial
The mod_dav_svn module for the Apache HTTP Server, as distributed in Apache Subversion 1.5.x and 1.6.x before 1.6.17, when the SVNPathAuthz short_circuit option is enabled, allows remote attackers to cause a denial of service (infinite loop and memory consumption) in opportunistic circumstances by requesting data.
9 CVE-2011-1752 DoS 2011-06-06 2017-09-18
5.0
None Remote Low Not required None None Partial
The mod_dav_svn module for the Apache HTTP Server, as distributed in Apache Subversion before 1.6.17, allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a request for a baselined WebDAV resource, as exploited in the wild in May 2011.
10 CVE-2011-0715 DoS 2011-03-11 2017-09-18
4.3
None Remote Medium Not required None None Partial
The mod_dav_svn module for the Apache HTTP Server, as distributed in Apache Subversion before 1.6.16, allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a request that contains a lock token.
11 CVE-2011-0534 399 DoS 2011-02-10 2017-08-16
5.0
None Remote Low Not required None None Partial
Apache Tomcat 7.0.0 through 7.0.6 and 6.0.0 through 6.0.30 does not enforce the maxHttpHeaderSize limit for requests involving the NIO HTTP connector, which allows remote attackers to cause a denial of service (OutOfMemoryError) via a crafted request.
12 CVE-2011-0419 399 DoS 2011-05-16 2017-09-18
4.3
None Remote Medium Not required None None Partial
Stack consumption vulnerability in the fnmatch implementation in apr_fnmatch.c in the Apache Portable Runtime (APR) library before 1.4.3 and the Apache HTTP Server before 2.2.18, and in fnmatch.c in libc in NetBSD 5.1, OpenBSD 4.8, FreeBSD, Apple Mac OS X 10.6, Oracle Solaris 10, and Android, allows context-dependent attackers to cause a denial of service (CPU and memory consumption) via *? sequences in the first argument, as demonstrated by attacks against mod_autoindex in httpd.
13 CVE-2010-4644 399 DoS 2011-01-07 2017-08-16
3.5
None Remote Medium Single system None None Partial
Multiple memory leaks in rev_hunt.c in Apache Subversion before 1.6.15 allow remote authenticated users to cause a denial of service (memory consumption and daemon crash) via the -g option to the blame command.
14 CVE-2010-4539 399 DoS 2011-01-07 2017-08-16
6.8
None Remote Low Single system None None Complete
The walk function in repos.c in the mod_dav_svn module for the Apache HTTP Server, as distributed in Apache Subversion before 1.6.15, allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via vectors that trigger the walking of SVNParentPath collections.
15 CVE-2007-6750 399 DoS 2011-12-27 2017-09-28
5.0
None Remote Low Not required None None Partial
The Apache HTTP Server 1.x and 2.x allows remote attackers to cause a denial of service (daemon outage) via partial HTTP requests, as demonstrated by Slowloris, related to the lack of the mod_reqtimeout module in versions before 2.2.15.
