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 •

https://notcve.org/view.php?id=CVE-2017-5334
Double free vulnerability in the gnutls_x509_ext_import_proxy function in GnuTLS before 3.3.26 and 3.5.x before 3.5.8 allows remote attackers to have unspecified impact via crafted policy language information in an X.509 certificate with a Proxy Certificate Information extension. La vulnerabilidad de liberación doble en la función gnutls_x509_ext_import_proxy de GnuTLS en versiones anteriores a 3.3.26 y 3.5.x en versiones anteriores a 3.5.8 permite a los atacantes remotos tener un impacto no especificado a través de una información de lenguaje de directivas elaborada en un certificado X.509 con una extensión Proxy Certificate Information. A double-free flaw was found in the way GnuTLS parsed certain X.509 certificates with Proxy Certificate Information extension. An attacker could create a specially-crafted certificate which, when processed by an application compiled against GnuTLS, could cause that application to crash. • http://lists.opensuse.org/opensuse-security-announce/2017-02/msg00005.html http://www.openwall.com/lists/oss-security/2017/01/10/7 http://www.openwall.com/lists/oss-security/2017/01/11/4 http://www.securityfocus.com/bid/95370 http://www.securitytracker.com/id/1037576 https://access.redhat.com/errata/RHSA-2017:2292 https://gitlab.com/gnutls/gnutls/commit/c5aaa488a3d6df712dc8dff23a049133cab5ec1b https://gnutls.org/security.html#GNUTLS-SA-2017-1 https://security.gentoo.org/glsa/201702 • CWE-415: Double Free CWE-416: Use After Free •
