Apache Software Foundation Subversion

A maliciously constructed svn+ssh:// URL would cause Subversion clients before 1.8.19, 1.9.x before 1.9.7, and 1.10.0.x through 1.10.0-alpha3 to run an arbitrary shell command. Such a URL could be generated by a malicious server, by a malicious user committing to a honest server (to attack another user of that server's repositories), or by a proxy server. The vulnerability affects all clients, including those that use file://, http://, and plain (untunneled) svn://.

Integer overflow in the read_string function in libsvn_ra_svn/marshal.c in Apache Subversion 1.9.x before 1.9.3 allows remote attackers to execute arbitrary code via an svn:// protocol string, which triggers a heap-based buffer overflow and an out-of-bounds read.

libsvn_fs_fs/fs_fs.c in Apache Subversion 1.8.x before 1.8.2 might allow remote authenticated users with commit access to corrupt FSFS repositories and cause a denial of service or obtain sensitive information by editing packed revision properties.

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 svnserve server in Subversion before 1.6.23 and 1.7.x before 1.7.10 allows remote attackers to cause a denial of service (exit) by aborting a connection.

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.

Remote unauthenticated denial-of-service in Subversion mod_authz_svn

Apache Subversion mod_dav_svn is vulnerable to memory corruption

In Apache Subversion versions up to and including 1.9.10, 1.10.4, 1.12.0, Subversion's svnserve server process may exit when a client sends certain sequences of protocol commands. This can lead to disruption for users of the server.

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 1.7.0 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 (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 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.

mod_authz_svn in Apache Subversion 1.7.x before 1.7.21 and 1.8.x before 1.8.14, when using Apache httpd 2.4.x, does not properly restrict anonymous access, which allows remote anonymous users to read hidden files via the path name.

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 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.
