Security issues fixed:
- CVE-2017-12837: Heap-based buffer overflow in the S_regatom function in
 regcomp.c in Perl 5 before 5.24.3-RC1 and 5.26.x before 5.26.1-RC1
 allows remote attackers to cause a denial of service (out-of-bounds
 write) via a regular expression with a '\N{}' escape and the
 case-insensitive modifier. (bnc#1057724)
- CVE-2017-12883: Buffer overflow in the S_grok_bslash_N function in
 regcomp.c in Perl 5 before 5.24.3-RC1 and 5.26.x before 5.26.1-RC1
 allows remote attackers to disclose sensitive information
 or cause a denial of service (application crash) via a crafted regular
 expression with an invalid '\N{U+...}' escape. (bnc#1057721)
- CVE-2017-6512: Race condition in the rmtree and remove_tree functions in
 the File-Path module before 2.13 for Perl allows attackers to set the
 mode on arbitrary files via vectors involving directory-permission
 loosening logic. (bnc#1047178)
Bug fixes:
- backport set_capture_string changes from upstream (bsc#999735)
- reformat baselibs.conf as source validator workaround");
