Updated pcre packages fix security vulnerabilities:

The pcrecompile2 function in pcrecompile.c in PCRE 8.38 mishandles a paricular pattern and related patterns with named subgroups, which allows remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via a crafted regular expression (CVE-2016-1283).

The compilebranch function in pcrecompile.c in PCRE 8.x before 8.39 mishandles patterns containing an (*ACCEPT) substring in conjunction with nested parentheses, which allows remote attackers to execute arbitrary code or cause a denial of service (stack-based buffer overflow) via a crafted regular expression (CVE-2016-3191).

The pcre package has been updated to the latest CVS as of May 21, 2016, aka 8.39-RC1, which fixes these issues, as well as several other bugs, and possible security issues.
