CVSS: 7.5EPSS: 29%CPEs: 34EXPL: 0CVE-2016-6302 – openssl: Insufficient TLS session ticket HMAC length checks
https://notcve.org/view.php?id=CVE-2016-6302
The tls_decrypt_ticket function in ssl/t1_lib.c in OpenSSL before 1.1.0 does not consider the HMAC size during validation of the ticket length, which allows remote attackers to cause a denial of service via a ticket that is too short. La función tls_decrypt_ticket en ssl/t1_lib.c en OpenSSL en versiones anteriores a 1.1.0 no considera el tamaño HMAC durante la validación de la longitud del ticket, lo que permite a atacantes remotos provocar una denegación de servicio a través de un ticket que es muy corto. An integer underflow flaw leading to a buffer over-read was found in the way OpenSSL parsed TLS session tickets. A remote attacker could use this flaw to crash a TLS server using OpenSSL if it used SHA-512 as HMAC for session tickets. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10759 http://rhn.redhat.com/errata/RHSA-2016-1940.html http://www-01.ibm.com/support/docview.wss?uid=swg21995039 http://www.oracle.com/technetwork/security-advisory/cpuapr2018-3678067.html http://www.oracle.com/technetwork/security-advisory/cpujan2018-3236628.html http://www.oracle.com/technetwork/security-advisory/cpujul2017-3236622.html http://www.oracle.com/technetwork/security-advisory/cpuoct2016-2881722.html http://www.oracle.com/technetwork& • CWE-20: Improper Input Validation CWE-125: Out-of-bounds Read •
CVSS: 7.5EPSS: 59%CPEs: 32EXPL: 0CVE-2016-2181 – openssl: DTLS replay protection bypass allows DoS against DTLS connection
https://notcve.org/view.php?id=CVE-2016-2181
The Anti-Replay feature in the DTLS implementation in OpenSSL before 1.1.0 mishandles early use of a new epoch number in conjunction with a large sequence number, which allows remote attackers to cause a denial of service (false-positive packet drops) via spoofed DTLS records, related to rec_layer_d1.c and ssl3_record.c. La funcionalidad Anti-Replay en la implementación DTLS en OpenSSL en versiones anteriores a 1.1.0 no maneja adecuadamente el uso temprano de un número de época nuevo en conjunción con un número de secuencia larga, lo que permite a atacantes remotos provocar una denegación de servicio (gotas de paquetes falsos positivos) a través de registros DTLS suplantados, relacionado con rec_layer_d1.c y ssl3_record.c. A flaw was found in the Datagram TLS (DTLS) replay protection implementation in OpenSSL. A remote attacker could possibly use this flaw to make a DTLS server using OpenSSL to reject further packets sent from a DTLS client over an established DTLS connection. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10759 http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00022.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00024.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2016-10/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2016-10/msg00011.h • CWE-20: Improper Input Validation CWE-189: Numeric Errors •

https://notcve.org/view.php?id=CVE-2016-7166
libarchive before 3.2.0 does not limit the number of recursive decompressions, which allows remote attackers to cause a denial of service (memory consumption and application crash) via a crafted gzip file. libarchive en versiones anteriores a 3.2.0 no limita el número de descompresiones recursivas, lo que permite a atacantes remotos provocar una denegación de servicio (consumo de memoria y caída de aplicación) a través de un archivo gzip manipulado. A vulnerability was found in libarchive. A specially crafted gzip file can cause libarchive to allocate memory without limit, eventually leading to a crash. • http://rhn.redhat.com/errata/RHSA-2016-1844.html http://rhn.redhat.com/errata/RHSA-2016-1850.html http://www.openwall.com/lists/oss-security/2016/09/08/15 http://www.openwall.com/lists/oss-security/2016/09/08/18 http://www.oracle.com/technetwork/topics/security/linuxbulletinjul2016-3090544.html http://www.securityfocus.com/bid/92901 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=207362 https://bugzilla.redhat.com/show_bug.cgi?id=1347086 https://github.com/libarchiv • CWE-399: Resource Management Errors CWE-770: Allocation of Resources Without Limits or Throttling •

https://notcve.org/view.php?id=CVE-2016-5418
The sandboxing code in libarchive 3.2.0 and earlier mishandles hardlink archive entries of non-zero data size, which might allow remote attackers to write to arbitrary files via a crafted archive file. El código sandboxing en libarchive 3.2.0 y versiones anteriores no maneja adecuadamente entradas de archivo de vínculo físico de datos de tamaño distinto de cero, lo que podría permitir a atacantes remotos escribir a archivos arbitrarios a través de un archivo manipulado. A flaw was found in the way libarchive handled hardlink archive entries of non-zero size. Combined with flaws in libarchive's file system sandboxing, this issue could cause an application using libarchive to overwrite arbitrary files with arbitrary data from the archive. • http://rhn.redhat.com/errata/RHSA-2016-1844.html http://rhn.redhat.com/errata/RHSA-2016-1850.html http://www.openwall.com/lists/oss-security/2016/08/09/2 http://www.oracle.com/technetwork/topics/security/linuxbulletinjul2016-3090544.html http://www.securityfocus.com/bid/93165 https://access.redhat.com/errata/RHSA-2016:1852 https://access.redhat.com/errata/RHSA-2016:1853 https://bugzilla.redhat.com/show_bug.cgi?id=1362601 https://gist.github.com/anonymous/e48209b03f1dd9625a992717e7b8 • CWE-19: Data Processing Errors CWE-20: Improper Input Validation CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

https://notcve.org/view.php?id=CVE-2016-5404
The cert_revoke command in FreeIPA does not check for the "revoke certificate" permission, which allows remote authenticated users to revoke arbitrary certificates by leveraging the "retrieve certificate" permission. El comando cert_revoke en FreeIPA no realiza comprobaciones para el permiso "certificado de revocación", lo que permite a usuarios remotos autenticados revocar certificados arbitrarios aprovechando el permiso "certificado de recuperación". An insufficient permission check issue was found in the way IPA server treats certificate revocation requests. An attacker logged in with the 'retrieve certificate' permission enabled could use this flaw to revoke certificates, possibly triggering a denial of service attack. • http://rhn.redhat.com/errata/RHSA-2016-1797.html http://www.openwall.com/lists/oss-security/2016/08/17/9 http://www.oracle.com/technetwork/topics/security/linuxbulletinjul2016-3090544.html http://www.securityfocus.com/bid/92525 https://fedorahosted.org/freeipa/ticket/6232 https://git.fedorahosted.org/cgit/freeipa.git/commit/?id=cf74584d0f772f3f5eccc1d30c001e4212a104fd https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/3PZ2ZQTMGC2UBRNHXVVOY3PJDOBP4CP4 https://lists.fedorap • CWE-284: Improper Access Control CWE-285: Improper Authorization •
