FreeBSD : subversion -- several vulnerabilities (83a418cc-2182-11e4-802c-20cf30e32f6d)

Synopsis :

The remote FreeBSD host is missing one or more security-related

Description :

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.
