CVSS: 7.5EPSS: 28%CPEs: 1EXPL: 0CVE-2017-7507 – gnutls: Crash upon receiving well-formed status_request extension
https://notcve.org/view.php?id=CVE-2017-7507
GnuTLS version 3.5.12 and earlier is vulnerable to a NULL pointer dereference while decoding a status response TLS extension with valid contents. This could lead to a crash of the GnuTLS server application. GnuTLS versión 3.5.12 y anteriores, es vulnerable a una desreferencia del puntero NULL durante la descodificación de una extensión TLS de respuesta de estado con contenido válido. Esto podría conllevar a un bloqueo de la aplicación del servidor GnuTLS. A null pointer dereference flaw was found in the way GnuTLS processed ClientHello messages with status_request extension. • http://www.debian.org/security/2017/dsa-3884 http://www.securityfocus.com/bid/99102 https://access.redhat.com/errata/RHSA-2017:2292 https://www.gnutls.org/security.html#GNUTLS-SA-2017-4 https://access.redhat.com/security/cve/CVE-2017-7507 https://bugzilla.redhat.com/show_bug.cgi?id=1454621 • CWE-476: NULL Pointer Dereference •
CVSS: 8.1EPSS: 0%CPEs: 1EXPL: 0CVE-2017-7869 – gnutls: Out-of-bounds write related to the cdk_pkt_read function (GNUTLS-SA-2017-3)
https://notcve.org/view.php?id=CVE-2017-7869
GnuTLS before 2017-02-20 has an out-of-bounds write caused by an integer overflow and heap-based buffer overflow related to the cdk_pkt_read function in opencdk/read-packet.c. This issue (which is a subset of the vendor's GNUTLS-SA-2017-3 report) is fixed in 3.5.10. GnuTLS en versiones anteriores a 20-02-2017 tiene una escritura fuera de límites provocado por un desbordamiento de entero y desbordamiento de búfer basado en memoria dinámica en relación con la función cdk_pkt_read en opencdk/read-packet.c. Este problema (que es un subconjunto del informe GNUTLS-SA-2017-3 del proveedor) se fija en 3.5.10. • http://www.securityfocus.com/bid/97040 https://access.redhat.com/errata/RHSA-2017:2292 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=420 https://gitlab.com/gnutls/gnutls/commit/51464af713d71802e3c6d5ac15f1a95132a354fe https://www.gnutls.org/security.html https://access.redhat.com/security/cve/CVE-2017-7869 https://bugzilla.redhat.com/show_bug.cgi?id=1443033 • CWE-787: Out-of-bounds Write •
