| CVE-2025-58050 | CRÍTICO9.1 | 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/p | 27/08/2025 |
| CVE-2022-41409 | ALTO7.5 | Integer overflow vulnerability in pcre2test before 10.41 allows attackers to cause a denial of service or other unspecified impacts via negative input. | 18/07/2023 |
| CVE-2022-1587 | CRÍTICO9.1 | 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. | 16/05/2022 |
| CVE-2022-1586 | CRÍTICO9.1 | 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.

| CVE-2019-20454 | ALTO7.5 | 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_ex | 14/02/2020 |
| CVE-2017-8786 | CRÍTICO9.8 | pcre2test.c in PCRE2 10.23 allows remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via a crafted regular expression. | 05/05/2017 |
| CVE-2017-8399 | CRÍTICO9.8 | PCRE2 before 10.30 has an out-of-bounds write caused by a stack-based buffer overflow in pcre2_match.c, related to a "pattern with very many captures." | 01/05/2017 |
| CVE-2017-7186 | ALTO7.5 | libpcre1 in PCRE 8.40 and libpcre2 in PCRE2 10.23 allow remote attackers to cause a denial of service (segmentation violation for read access, and application crash) by triggering an invalid Unicode property lookup. | 20/03/2017 |
| CVE-2015-3217 | ALTO7.5 | PCRE 7.8 and 8.32 through 8.37, and PCRE2 10.10 mishandle group empty matches, which might allow remote attackers to cause a denial of service (stack-based buffer overflow) via a crafted regular expression, as demonstrated by /^(?:(?(1)\\.|([^\\\\W_])?)+)+$/. | 13/12/2016 |
| CVE-2015-3210 | CRÍTICO9.8 | Heap-based buffer overflow in PCRE 8.34 through 8.37 and PCRE2 10.10 allows remote attackers to execute arbitrary code via a crafted regular expression, as demonstrated by /^(?P=B)((?P=B)(?J:(?P<B>c)(?P<B>a(?P=B)))>WGXCREDITS)/, a different vulnerability than CVE-2015-8384. | 13/12/2016 |
