Fedora Update Notification
FEDORA-2020-b57b820977
2020-02-26 17:58:38.930072
--------------------------------------------------------------------------------
Name : pcre2
Product : Fedora 31
Version : 10.34
Release : 7.fc31
URL : https://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. This package provides support for strings in 8-bit and UTF-8
encodings. Install pcre2-utf16 or pcre2-utf32 packages for the other ones.
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 in a JIT code when processing an invalid UTF-8 string
was requested and an invalid UTF-8 character was indeed encountered. ---- This
release fixes a JIT miscompilation of the chained verbs that can lead to a crash
of the process.
