05 Jun 2020 — regcomp.c in Perl before 5.30.3 allows a buffer overflow via a crafted regular expression because of recursive S_study_chunk calls. En el archivo regcomp.c en Perl versiones anteriores a 5.30.3, permite un desbordamiento del búfer por medio de una expresión regular diseñada debido a llamadas recursivas de la función S_study_chunk ManhND discovered that Perl incorrectly handled certain regular expressions.

05 Jun 2020 — Perl before 5.30.3 has an integer overflow related to mishandling of a "PL_regkind[OP(n)] == NOTHING" situation. A crafted regular expression could lead to malformed bytecode with a possibility of instruction injection. Perl versiones anteriores a 5.30.3, presenta un desbordamiento de enteros relacionado con un manejo inapropiado de una situación "PL_regkind[OP(n)] == NOTHING".

CVSS: 7.5EPSS: 60%CPEs: 18EXPL: 4CVE-2017-3730 – Bad (EC)DHE parameters cause a client crash
https://notcve.org/view.php?id=CVE-2017-3730
26 Jan 2017 — In OpenSSL 1.1.0 before 1.1.0d, if a malicious server supplies bad parameters for a DHE or ECDHE key exchange then this can result in the client attempting to dereference a NULL pointer leading to a client crash. This could be exploited in a Denial of Service attack. En OpenSSL versión 1.1.0 anterior a 1.1.0d, si un servidor malicioso suministra parámetros incorrectos para un intercambio de claves DHE o ECDHE, entonces esto puede resultar en que el cliente intente desreferenciar un puntero NULL que conduce ... • https://packetstorm.news/files/id/140804 • CWE-476: NULL Pointer Dereference •
