Fedora Update Notification
FEDORA-2017-3b367c896f
2017-05-09 21:16:27.649666
--------------------------------------------------------------------------------


Name : pcre
Product : Fedora 24
Version : 8.40
Release : 7.fc24
URL : http://www.pcre.org/
Summary : Perl-compatible regular expression library
Description :
PCRE, Perl-compatible regular expression, library has its own native API, but
a set of wrapper functions that are based on the POSIX API are also supplied
in the libpcreposix library. Note that this just provides a POSIX calling
interface to PCRE: the regular expressions themselves still follow Perl syntax
and semantics. Detailed change log is provided by pcre-doc package.

This release fixes a crash when finding a Unicode property for a character
with
a code point greater than 0x10ffff in UTF-32 library while UTF mode is
disabled
and JIT mde enabled. It also fixes a buffer overlflow in pcretest tool when
copying a string in UTF-32 mode.
