Уязвимость функции do_extuni_no_utf компонента pcre2_jit_compile.c библиотеки регулярных выражений PCRE2, позволяющая нарушителю вызвать отказ в обслуживании

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.

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.

An out-of-bounds read vulnerability was discovered in the PCRE2 library in the get_recurse_data_length() function of the pcre2_jit_compile.c file. This issue affects recursions in JIT-compiled regular expressions caused by duplicate data transfers.
