Subversion team reports:

Subversion's mod_dav_svn Apache HTTPD server module will use excessive amounts of memory when a large number of properties are set or deleted on a node.

Subversion's mod_dav_svn Apache HTTPD server module will crash when a LOCK request is made against activity URLs.

Subversion's mod_dav_svn Apache HTTPD server module will crash in some circumstances when a LOCK request is made against a non-existent URL.

Subversion's mod_dav_svn Apache HTTPD server module will crash when a PROPFIND request is made against activity URLs.

Subversion's mod_dav_svn Apache HTTPD server module will crash when a log REPORT request receives a limit that is out of the allowed range.

In some situations, subversion metadata may be unexpectedly disclosed via WebDAV. A subversion advisory states:

mod_authz_svn, the Apache httpd module which does path-based authorization on Subversion repositories, is not correctly protecting all metadata on unreadable paths.

This security issue is not about revealing the contents of protected files: it only reveals metadata about protected areas such as paths and log messages. This may or may not be important to your organization, depending on how you're using path-based authorization, and the sensitivity of the metadata.

A Subversion Security Advisory reports:

Subversion clients and servers have multiple heap overflow issues in the parsing of binary deltas. This is related to an allocation vulnerability in the APR library used by Subversion.

Clients with commit access to a vulnerable server can cause a remote heap overflow; servers can cause a heap overflow on vulnerable clients that try to do a checkout or update.

This can lead to a DoS (an exploit has been tested) and to arbitrary code execution (no exploit tested, but the possibility is clear).

< 1.6.4

Subversion team reports:

Subversion's mod_dav_svn Apache HTTPD server module will dereference a NULL pointer if asked to deliver baselined WebDAV resources.

This can lead to a DoS. An exploit has been tested, and tools or users have been observed triggering this problem in the wild.

Subversion's mod_dav_svn Apache HTTPD server module may in certain scenarios enter a logic loop which does not exit and which allocates memory in each iteration, ultimately exhausting all the available memory on the server.

This can lead to a DoS. There are no known instances of this problem being observed in the wild, but an exploit has been tested.

Subversion's mod_dav_svn Apache HTTPD server module may leak to remote users the file contents of files configured to be unreadable by those users.

There are no known instances of this problem being observed in the wild, but an exploit has been tested.

The Apache Software Foundation reports:

The mod_dontdothat module of subversion and subversion clients using http(s):// are vulnerable to a denial-of-service attack, caused by exponential XML entity expansion. The attack targets XML parsers causing targeted process to consume excessive amounts of resources. The attack is also known as the "billions of laughs attack."

Subversion team reports:

Subversion's svnserve server process may exit when an incoming TCP connection is closed early in the connection process.

Subversion project reports:

svnserve, the svn:// protocol server, can optionally use the Cyrus SASL library for authentication, integrity protection, and encryption. Due to a programming oversight, authentication against Cyrus SASL would permit the remote user to specify a realm string which is a prefix of the expected realm string.

Subversion's httpd servers are vulnerable to a remotely triggerable crash in the mod_authz_svn module. The crash can occur during an authorization check for a COPY or MOVE request with a specially crafted header value.

This allows remote attackers to cause a denial of service.

Subversion Project reports:

Using the Serf RA layer of Subversion for HTTPS uses the apr_fnmatch API to handle matching wildcards in certificate Common Names and Subject Alternate Names. However, apr_fnmatch is not designed for this purpose. Instead it is designed to behave like common shell globbing. In particular this means that '*' is not limited to a single label within a hostname (i.e. it will match '.'). But even further apr_fnmatch supports '?' and character classes (neither of which are part of the RFCs defining how certificate validation works).

Subversion stores cached credentials by an MD5 hash based on the URL and the authentication realm of the server the credentials are cached for. MD5 has been shown to be subject to chosen plaintext hash collisions. This means it may be possible to generate an authentication realm which results in the same MD5 hash for a different URL.

Subversion Project reports:

Subversion HTTP servers with FSFS repositories are vulnerable to a remotely triggerable excessive memory use with certain REPORT requests.

Subversion mod_dav_svn and svnserve are vulnerable to a remotely triggerable assertion DoS vulnerability for certain requests with dynamically evaluated revision numbers.

Subversion HTTP servers allow spoofing svn:author property values for new revisions.

Entry for CVE-2010-4539 says:

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.

Entry for CVE-2010-4644 says:

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.

Subversion Project reports:

Subversion's mod_dav_svn Apache HTTPD server module will crash when it receives a REPORT request for some invalid formatted special URIs.

Subversion's mod_dav_svn Apache HTTPD server module will crash when it receives a request for some invalid formatted special URIs.

We consider this to be a medium risk vulnerability. Repositories which allow for anonymous reads will be vulnerable without authentication. Unfortunately, no special configuration is required and all mod_dav_svn servers are vulnerable.

Stefan Esser reports:

Subversion versions up to 1.0.2 are vulnerable to a date parsing vulnerability which can be abused to allow remote code execution on Subversion servers and therefore could lead to a repository compromise.

NOTE: This vulnerability is similar to the date parsing issue that affected neon. However, it is a different and distinct bug.
