The pcre_compile2 function in pcre_compile.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 compile_branch function in pcre_compile.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.");
