    Perl-compatible regular expression library.
    PCRE has its own native API, but a set of wrapper functions that are based on
    the POSIX API are also supplied in the library libpcreposix. Note that this
    just provides a POSIX calling interface to PCRE: the regular expressions
    themselves still follow Perl syntax and semantics. The header file
    for the POSIX-style functions is called pcreposix.h.
    Security issues fixed with this release:
    CVE-2015-2328
    PCRE before 8.36 mishandles the /((?(R)a|(?1))) / pattern and related
    patterns with certain recursion, which allows remote attackers to
    cause a denial of service (segmentation fault) or possibly have
    unspecified other impact via a crafted regular expression, as
    demonstrated by a JavaScript RegExp object encountered by Konqueror.
    CVE-2015-3217
    ** RESERVED **
    This candidate has been reserved by an organization or individual that
    will use it when announcing a new security problem.  When the
    candidate has been publicized, the details for this candidate will be
    provided.
    CVE-2015-5073
    ** RESERVED **
    This candidate has been reserved by an organization or individual that
    will use it when announcing a new security problem.  When the
    candidate has been publicized, the details for this candidate will be
    provided.
    CVE-2015-8385
    PCRE before 8.38 mishandles the /(?|(\k'Pm')|(?'Pm'))/ pattern and
    related patterns with certain forward references, which allows remote
    attackers to cause a denial of service (buffer overflow) or possibly
    have unspecified other impact via a crafted regular expression, as
    demonstrated by a JavaScript RegExp object encountered by Konqueror.
    CVE-2015-8386
    PCRE before 8.38 mishandles the interaction of lookbehind assertions
    and mutually recursive subpatterns, which allows remote attackers to
    cause a denial of service (buffer overflow) or possibly have
    unspecified other impact via a crafted regular expression, as
    demonstrated by a JavaScript RegExp object encountered by Konqueror.
    CVE-2015-8388
    PCRE before 8.38 mishandles the /(?=di(?<=(?1))|(?=(.))))/ pattern and
    related patterns with an unmatched closing parenthesis, which allows
    remote attackers to cause a denial of service (buffer overflow) or
    possibly have unspecified other impact via a crafted regular
    expression, as demonstrated by a JavaScript RegExp object encountered
    by Konqueror.
    CVE-2015-8391
    The pcre_compile function in pcre_compile.c in PCRE before 8.38
    mishandles certain [: nesting, which allows remote attackers to cause
    a denial of service (CPU consumption) or possibly have unspecified
    other impact via a crafted regular expression, as demonstrated by a
    JavaScript RegExp object encountered by Konqueror.
    CVE-2016-3191
    The compile_branch function in pcre_compile.c in PCRE 8.x before 8.39
    and pcre2_compile.c in PCRE2 before 10.22 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, as demonstrated by a JavaScript RegExp
    object encountered by Konqueror, aka ZDI-CAN-3542.
