Apache Software Foundation Subversion 1.4.3

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.

Apache Subversion's mod_dontdothat module and HTTP clients 1.4.0 through 1.8.16, and 1.9.0 through 1.9.4 are vulnerable to a denial-of-service attack caused by exponential XML entity expansion. The attack can cause the targeted process to consume an excessive amount of CPU resources or memory.

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 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 1.6.16, allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a request that contains a lock token.

Apache Subversion 1.0.0 through 1.7.x before 1.7.17 and 1.8.x before 1.8.10 uses an MD5 hash of the URL and authentication realm to store cached credentials, which makes it easier for remote servers to obtain the credentials via a crafted authentication realm.

The Serf RA layer in Apache Subversion 1.4.0 through 1.7.x before 1.7.18 and 1.8.x before 1.8.10 does not properly handle wildcards in the Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof servers via a crafted certificate.

The (1) serf_ssl_cert_issuer, (2) serf_ssl_cert_subject, and (3) serf_ssl_cert_certificate functions in Serf 0.2.0 through 1.3.x before 1.3.7 does not properly handle a NUL byte in a domain name in the subject's Common Name (CN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority.

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.

Svnserve in Apache Subversion 1.4.0 through 1.7.12 and 1.8.0 through 1.8.1 allows local users to overwrite arbitrary files or kill arbitrary processes via a symlink attack on the file specified by the --pid-file option.

The is_this_legal function in mod_dontdothat for Apache Subversion 1.4.0 through 1.7.13 and 1.8.0 through 1.8.4 allows remote attackers to bypass intended access restrictions and possibly cause a denial of service (resource consumption) via a relative URL in a REPORT request.
