Fedora 36 FEDORA-2022-e56085ba31 Critical: pcre2 Out-Of-Bounds Read Fix

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.
