Multiple out-of-bounds read vulnerabilities were found in pcre2, a Perl
Compatible Regular Expression library, which could result in information
disclosure or denial or service.

An out-of-bounds read vulnerability was discovered in the PCRE2 library
in the compile_xclass_matchingpath() function of the pcre2_jit_compile.c
file. This involves a unicode property matching issue in JIT-compiled
regular expressions. The issue occurs because the character was not
fully read in case-less matching within JIT.

Additionally, this upload also fixes a subject buffer overread in JIT
when UTF is disabled and \X or \R has a greater than 1 fixed quantifier.
