An update that has five security fixes can now be installed.

## Description:

This update for libarchive fixes the following issues:

  * creating temporary files in the current working directory instead of the
    target directory can lead to file creation failures when the working
    directory is not writable (bsc#1254340).
  * file descriptor leak in the mtree parser cleanup path could lead to file
    descriptor exhaustion and denial of service (bsc#1261003).
  * NULL pointer dereference in archive_acl_from_text_w() could lead to a
    segmentation fault (bsc#1260998).
  * reading from an invalid index when buffer size is smaller than
    H_LEVEL_OFFSET can lead to an out-of-bounds buffer overrun (bsc#1254341).
  * incorrect pointer handling for RAR5 files declaring over 8192 filters can
    lead to excessive resource usage and denial of service (bsc#1261002).
