Perl before 5.26.3 has a buffer over-read via a crafted regular expression that triggers disclosure of sensitive information from process memory. Perl, en versiones anteriores a la 5.26.3, tiene una sobrelectura de búfer mediante una expresión regular manipulada que desencadena la divulgación de información sensible de la memoria del proceso. • http://seclists.org/fulldisclosure/2019/Mar/49 http://www.securitytracker.com/id/1042181 https://access.redhat.com/errata/RHSA-2019:0001 https://access.redhat.com/errata/RHSA-2019:0010 https://bugzilla.redhat.com/show_bug.cgi?id=1646738 https://github.com/Perl/perl5/commit/43b2f4ef399e2fd7240b4eeb0658686ad95f8e62 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/RWQGEB543QN7SSBRKYJM6PSOC3RLYGSM https://metacpan.org/changes/release/SHAY/perl-5.26.3 https://rt& • CWE-125: Out-of-bounds Read •

Samba from version 4.3.0 and before versions 4.7.12, 4.8.7 and 4.9.3 are vulnerable to a denial of service. When configured to accept smart-card authentication, Samba's KDC will call talloc_free() twice on the same memory if the principal in a validly signed certificate does not match the principal in the AS-REQ. This is only possible after authentication with a trusted certificate. talloc is robust against further corruption from a double-free with talloc_free() and directly calls abort(), terminating the KDC process. Samba, desde la versión 4.3.0 antes de las versiones 4.7.12, 4.8.7 y 4.9.3, es vulnerable a una denegación de servicio (DoS). Cuando se configura para aceptar la autenticación por smartcard, el KDC de Samba llamará a talloc_free() dos veces en la misma memoria si la entidad de seguridad en un certificado firmado de forma válida no coincide con la entidad en AS-REQ. • http://www.securityfocus.com/bid/106023 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-16841 https://security.gentoo.org/glsa/202003-52 https://security.netapp.com/advisory/ntap-20181127-0001 https://usn.ubuntu.com/3827-1 https://usn.ubuntu.com/3827-2 https://www.debian.org/security/2018/dsa-4345 https://www.samba.org/samba/security/CVE-2018-16841.html • CWE-415: Double Free CWE-416: Use After Free •

Samba from version 4.0.0 and before versions 4.7.12, 4.8.7, 4.9.3 is vulnerable to a denial of service. During the processing of an LDAP search before Samba's AD DC returns the LDAP entries to the client, the entries are cached in a single memory object with a maximum size of 256MB. When this size is reached, the Samba process providing the LDAP service will follow the NULL pointer, terminating the process. There is no further vulnerability associated with this issue, merely a denial of service.

A denial of service vulnerability was discovered in Samba's LDAP server before versions 4.7.12, 4.8.7, and 4.9.3. A CNAME loop could lead to infinite recursion in the server. An unprivileged local attacker could create such an entry, leading to denial of service. Se ha descubierto una vulnerabilidad de denegación de servicio (DoS) en el servidor LDAP de Samba en versiones anteriores a la 4.7.12, 4.8.7, y 4.9.3. Un bucle CNAME podría conducir a una recursión infinita en el servidor. • http://www.securityfocus.com/bid/106022 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14629 https://lists.debian.org/debian-lts-announce/2018/12/msg00005.html https://security.gentoo.org/glsa/202003-52 https://security.netapp.com/advisory/ntap-20181127-0001 https://usn.ubuntu.com/3827-1 https://usn.ubuntu.com/3827-2 https://www.debian.org/security/2018/dsa-4345 https://www.samba.org/samba/security/CVE-2018-14629.html • CWE-400: Uncontrolled Resource Consumption CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
