CVE-2022-1586 WRITEUP CRITICAL WRITEUP
PCRE2 < 10.40 - Out-of-bounds Read in JIT Unicode Property Matching
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-2017-9250 WRITEUP HIGH WRITEUP
JerryScript 1.0 - Denial of Service via Malformed JavaScript Source Code
The lexer_process_char_literal function in jerry-core/parser/js/js-lexer.c in JerryScript 1.0 does not skip memory allocation for empty strings, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via malformed JavaScript source code, related to the jmem_heap_free_block function.

CVE-2025-58050 WRITEUP CRITICAL WRITEUP
PCRE2 < 10.46 - Out-of-bounds Read via (*scs:...) and (*ACCEPT) Handling
The PCRE2 library is a set of C functions that implement regular expression pattern matching. In version 10.45, a heap-buffer-overflow read vulnerability exists in the PCRE2 regular expression matching engine, specifically within the handling of the (*scs:...) (Scan SubString) verb when combined with (*ACCEPT) in src/pcre2_match.c. This vulnerability may potentially lead to information disclosure if the out-of-bounds data read during the memcmp affects the final match result in a way observable by the attacker. This issue has been resolved in version 10.46.
