vulnerability:
- 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. (CVE-2022-1586)
