Package : apr-util
Type    : denial of service
Remote  : No
Link    : https://security.archlinux.org/AVG-468

Summary
=======

The package apr-util before version 1.6.1-1 is vulnerable to denial of
service.

Resolution

Upgrade to 1.6.1-1.

# pacman -Syu "apr-util>=1.6.1-1"

The problem has been fixed upstream in version 1.6.1.

Workaround
==========

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

APR-util 1.6.0 and prior failed to validate the integrity of SDBM
database files used by apr_sdbm*() functions, resulting in a possible

database can make a program or process using these functions crash, and
cause a denial of service.

Impact

A local attacker with write access to the database can cause a denial
of service.
