Heap-based buffer overflow in the S_regatom function in regcomp.c in Perl 5 before 5.24.3-RC1 and 5.26.x before 5.26.1-RC1 allows remote attackers to cause a denial of service (out-of-bounds write) via a regular expression with a '\N{}' escape and the case-insensitive modifier. Un desbordamiento de búfer en la región heap de la memoria en la función S_regatom en el archivo regcomp.c en Perl 5 anterior a versión 5.24.3-RC1 y versión 5.26.x anterior a 5.26.1-RC1, permite a los atacantes remotos causar una denegación de servicio (escritura fuera de límites) por medio de una expresión regular con un escape '\N{}' y el modificador que no distingue entre mayúsculas y minúsculas. • http://www.debian.org/security/2017/dsa-3982 http://www.securityfocus.com/bid/100860 https://bugzilla.redhat.com/show_bug.cgi?id=1492091 https://perl5.git.perl.org/perl.git/commitdiff/96c83ed78aeea1a0496dd2b2d935869a822dc8a5 https://perl5.git.perl.org/perl.git/log/refs/tags/v5.24.3-RC1 https://perl5.git.perl.org/perl.git/log/refs/tags/v5.26.1-RC1 https://rt.perl.org/Public/Bug/Display.html?id=131582 https://security.netapp.com/advisory/ntap-20180426-0001 https://www • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

CVSS: 2.1EPSS: 0%CPEs: 2EXPL: 4CVE-2014-4330 – Perl 5.20.1 Deep Recursion Stack Overflow
https://notcve.org/view.php?id=CVE-2014-4330
The Dumper method in Data::Dumper before 2.154, as used in Perl 5.20.1 and earlier, allows context-dependent attackers to cause a denial of service (stack consumption and crash) via an Array-Reference with many nested Array-References, which triggers a large number of recursive calls to the DD_dump function. El método Dumper en Data::Dumper anterior a 2.154, utilizado en Perl 5.20.1 y anteriores, permite a atacantes dependientes de contexto causar una denegación de servicio (consumo de la pila y caída) a través de una referencia de array con muchas referencias de array anidadas, lo que provoca un número grande de llamadas recursivas a la función DD_dump. A stack overflow was discovered when serializing data via the Data::Dumper extension which is part of Perl-Core. By using the "Dumper" method on a large Array-Reference which recursively contains other Array-References, it is possible to cause many recursive calls to the DD_dump native function and ultimately exhaust all available stack memory. • http://advisories.mageia.org/MGASA-2014-0406.html http://lists.fedoraproject.org/pipermail/package-announce/2014-September/139441.html http://packetstormsecurity.com/files/128422/Perl-5.20.1-Deep-Recursion-Stack-Overflow.html http://seclists.org/fulldisclosure/2014/Sep/84 http://seclists.org/oss-sec/2014/q3/692 http://secunia.com/advisories/61441 http://secunia.com/advisories/61961 http://www.mandriva.com/security/advisories?name=MDVSA-2015:136 http://www.nntp.perl.org/group/perl.p • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
