The attack can cause the targeted process to consume an excessive amount of CPU resources or memory.(CVE-2016-8734)

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.(CVE-2015-5343)

The canonicalize_username function in svnserve/cyrus_auth.c in Apache Subversion before 1.8.16 and 1.9.x before 1.9.4, when Cyrus SASL authentication is used, allows remote attackers to authenticate and bypass intended access restrictions via a realm string that is a prefix of an expected repository realm string.(CVE-2016-2167)

The req_check_access function in the mod_authz_svn module in the httpd server in Apache Subversion before 1.8.16 and 1.9.x before 1.9.4 allows remote authenticated users to cause a denial of service (NULL pointer dereference and crash) via a crafted header in a (1) MOVE or (2) COPY request, involving an authorization check.(CVE-2016-2168)");
