Fedora EPEL Update Notification
FEDORA-EPEL-2017-58105a4f7f
2017-05-04 13:27:47.188224
--------------------------------------------------------------------------------
Name : pcre2
Product : Fedora EPEL 6
Version : 10.21
Release : 18.el6
URL :
http://www.pcre.org/
Summary : Perl-compatible regular expression library
Description :
PCRE2 is a re-working of the original PCRE (Perl-compatible regular
expression) library to provide an entirely new API.
PCRE2 is written in C, and it has its own API. There are three sets of
functions, one for the 8-bit library, which processes strings of bytes, one
for the 16-bit library, which processes strings of 16-bit values, and one for
the 32-bit library, which processes strings of 32-bit values. There are no C++
wrappers.
The distribution does contain a set of C wrapper functions for the 8-bit
library that are based on the POSIX regular expression API (see the pcre2posix
man page). These can be found in a library called libpcre2posix. Note that
this just provides a POSIX calling interface to PCRE2; the regular expressions
themselves still follow Perl syntax and semantics. The POSIX API is
restricted, and does not give full access to all of PCRE2's facilities.

Update Information:
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 mode is enabled. It also fixes an incortect cast in UTF validation
routine. ---- This release fixes DFA magch for a possessively repeated
character class and a memory allocator from the pattern if no context is
supplied to pcre2_match(). ---- This release closes serialization file in
pcre2test after any error and it fixes a potential NULL dereference in
pcre2_callout_enumerate() if called with a NULL pattern pointer when Unicode
support is available. ---- This release fixes a pcre2test bug for global match
with zero terminated subject.
