Subversion's mod_dav_svn is vulnerable to memory corruption. While looking up path-based authorization rules, mod_dav_svn servers may attempt to use memory which has already been freed. Affected Subversion mod_dav_svn servers 1.10.0 through 1.14.1 (inclusive). Servers that do not use mod_dav_svn are not affected.

Subversion's mod_authz_svn module will crash if the server is using in-repository authz rules with the AuthzSVNReposRelativeAccessFile option and a client sends a request for a non-existing repository URL. This can lead to disruption for users of the service. This issue was fixed in mod_dav_svn+mod_authz_svn servers 1.14.1 and mod_dav_svn+mod_authz_svn servers 1.10.7

Subversion's mod_dav_svn Apache HTTPD module versions 1.11.0 and 1.10.0 to 1.10.3 will crash after dereferencing an uninitialized pointer if the client omits the root path in a recursive directory listing operation.

The mod_dontdothat component of the mod_dav_svn Apache module in Subversion as packaged in Red Hat Enterprise Linux 5.11 does not properly detect recursion during entity expansion, which allows remote authenticated users with access to the webdav repository to cause a denial of service (memory consumption and httpd crash). NOTE: Exists as a regression to CVE-2009-1955.

Integer overflow in util.c in mod_dav_svn in Apache Subversion 1.7.x, 1.8.x before 1.8.15, and 1.9.x before 1.9.3 allows remote authenticated users to cause a denial of service (subversion server crash or memory consumption) and possibly execute arbitrary code via a skel-encoded request body, which triggers an out-of-bounds read and heap-based buffer overflow.

The mod_dav_svn server in Subversion 1.5.0 through 1.7.19 and 1.8.0 through 1.8.11 allows remote authenticated users to spoof the svn:author property via a crafted v1 HTTP protocol request sequences.

The (1) mod_dav_svn and (2) svnserve servers in Subversion 1.6.0 through 1.7.19 and 1.8.0 through 1.8.11 allow remote attackers to cause a denial of service (assertion failure and abort) via crafted parameter combinations related to dynamically evaluated revision numbers.

The mod_dav_svn server in Subversion 1.8.0 through 1.8.11 allows remote attackers to cause a denial of service (memory consumption) via a large number of REPORT requests, which trigger the traversal of FSFS repository nodes.

The mod_dav_svn Apache HTTPD server module in Apache Subversion 1.7.x before 1.7.19 and 1.8.x before 1.8.11 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via a request for a URI that triggers a lookup for a virtual transaction name that does not exist.

The mod_dav_svn Apache HTTPD server module in Apache Subversion 1.x before 1.7.19 and 1.8.x before 1.8.11 allows remote attackers to cause a denial of service (NULL pointer dereference and server crash) via a REPORT request for a resource that does not exist.

The dav_xml_get_cdata function in main/util.c in the mod_dav module in the Apache HTTP Server before 2.4.8 does not properly remove whitespace characters from CDATA sections, which allows remote attackers to cause a denial of service (daemon crash) via a crafted DAV WRITE request.

The get_resource function in repos.c in the mod_dav_svn module in Apache Subversion before 1.7.15 and 1.8.x before 1.8.6, when SVNListParentPath is enabled, allows remote attackers to cause a denial of service (crash) via vectors related to the server root and request methods other than GET, as demonstrated by the "svn ls http://svn.example.com" command.

The get_parent_resource function in repos.c in mod_dav_svn Apache HTTPD server module in Subversion 1.7.11 through 1.7.13 and 1.8.1 through 1.8.4, when built with assertions enabled and SVNAutoversioning is enabled, allows remote attackers to cause a denial of service (assertion failure and Apache process abort) via a non-canonical URL in a request, as demonstrated using a trailing /.

The mod_dav_svn Apache HTTPD server module in Subversion 1.7.0 through 1.7.10 and 1.8.x before 1.8.1 allows remote authenticated users to cause a denial of service (assertion failure or out-of-bounds read) via a certain (1) COPY, (2) DELETE, or (3) MOVE request against a revision root.

mod_dav.c in the Apache HTTP Server before 2.2.25 does not properly determine whether DAV is enabled for a URI, which allows remote attackers to cause a denial of service (segmentation fault) via a MERGE request in which the URI is configured for handling by the mod_dav_svn module, but a certain href attribute in XML data refers to a non-DAV URI.

The mod_dav_svn Apache HTTPD server module in Subversion 1.7.0 through 1.7.8 allows remote attackers to cause a denial of service (segmentation fault and crash) via a log REPORT request with an invalid limit, which triggers an access of an uninitialized variable.

The mod_dav_svn Apache HTTPD server module in Subversion 1.6.x through 1.6.20 and 1.7.0 through 1.7.8 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via a PROPFIND request for an activity URL.

The mod_dav_svn Apache HTTPD server module in Subversion 1.6.0 through 1.6.20 and 1.7.0 through 1.7.8 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via an anonymous LOCK for a URL that does not exist.

The mod_dav_svn Apache HTTPD server module in Subversion 1.6.x before 1.6.21 and 1.7.0 through 1.7.8 allows remote authenticated users to cause a denial of service (NULL pointer dereference and crash) via a LOCK on an activity URL.

The mod_dav_svn Apache HTTPD server module in Subversion 1.6.x before 1.6.21 and 1.7.0 through 1.7.8 allows remote authenticated users to cause a denial of service (memory consumption) by (1) setting or (2) deleting a large number of properties for a file or directory.
