libsvn_ra_svn in Subversion 1.0.4 trusts the length field of (1) svn://, (2) svn+ssh://, and (3) other svn protocol URL strings, which allows remote attackers to cause a denial of service (memory consumption) and possibly execute arbitrary code via an integer overflow that leads to a heap-based buffer overflow.

Stack-based buffer overflow during the apr_time_t data conversion in Subversion 1.0.2 and earlier allows remote attackers to execute arbitrary code via a (1) DAV2 REPORT query or (2) get-dated-rev svn-protocol command.
