   An update that solves two vulnerabilities and has two fixes
   is now available.

Description:

   This update for patch fixes the following issues:

   Security issues fixed:

   - CVE-2019-13636: Fixed follow symlinks unless --follow-symlinks is given.
     This increases the security against malicious patches (bsc#1142041).
   - CVE-2018-6952: Fixed swapping fakelines in pch_swap. This bug was
     causing a double free leading to a crash (bsc#1080985).

   Bugfixes:

   - Abort when cleaning up fails. This bug could cause an infinite loop when
     a patch wouldn't apply, leading to a segmentation fault (bsc#1111572).
   - Pass the correct stat to backup files. This bug would occasionally cause
     backup files to be missing when all hunks failed to apply (bsc#1198106).
