CVE: CVE-2019-20454


An out-of-bounds read was discovered in PCRE before 10.34 when the pattern
\X is JIT compiled and used to match specially crafted subjects in non-UTF
mode. Applications that use PCRE to parse untrusted input may be vulnerable
to this flaw, which would allow an attacker to crash the application. The
flaw occurs in do_extuni_no_utf in pcre2_jit_compile.c. (CVE-2019-20454)
