oniguruma: Heap-based buffer overflow in str_lower_case_match in regexec.c
Oniguruma through 6.9.3, as used in PHP 7.3.x and other products, has a heap-based buffer over-read in str_lower_case_match in regexec.c.
A vulnerability was found in Oniguruma, where improper bounds checking in str_lower_case_match within regexec.c can cause a heap-based buffer overflow, a remote attacker could exploit this flaw to crash the application or, in certain scenarios, execute arbitrary code. This occurs when the application processes specially crafted regex patterns, potentially leading to unintended behavior.
Statement: This vulnerability is rated as moderate because a heap-based buffer overflow in Oniguruma’s str_lower_case_match within regexec.c could lead to application crashes or potential code e
