DESCRIPTION:
Two vulnerabilities have been reported in Apache Subversion, which
can be exploited by malicious people to cause a DoS (Denial of
Service).

1) A NULL pointer dereference error in the mod_dav_svn module when
processing baselined resource requests can be exploited to cause a
crash.

This vulnerability is reported in versions 1.6.16 and prior.

2) An error within the mod_dav_svn module when handling certain
path-based access control rules can be exploited to trigger an
infinite loop and exhaust memory.

This vulnerability is reported in versions 1.5.0 through 1.6.16.

NOTE: A weakness in the handling of path-based access control rules,
which could result in certain unreadable files and directories
becoming readable has also been reported.

SOLUTION:
Update to version 1.6.17.

PROVIDED AND/OR DISCOVERED BY:
1) Reported by the vendor
2) The vendor credits Ivan Zhakov, VisualSVN.
