==========================================

Severity: High
Date    : 2019-01-28
CVE-ID  : CVE-2018-11803
Package : subversion
Type    : denial of service
Remote  : Yes
Link    : https://security.archlinux.org/AVG-858

Summary
=======

The package subversion before version 1.11.1-1 is vulnerable to denial
of service.

Resolution
==========

Upgrade to 1.11.1-1.

# pacman -Syu "subversion>=1.11.1-1"

The problem has been fixed upstream in version 1.11.1.

Workaround
==========

None.

Description
===========

A denial of service has been found in subversion versions prior to
1.11.1, allowing a malicious SVN client to crash a remote server using
mod_dav_svn by omitting the root path from a recursive directory
listing request, causing mod_dav_svn to dereference an uninitialized
pointer variable and crash the httpd worker process handling the
request.

Impact
======

A remote attacker is able to crash the server by sending a specially
crafted request.
