Multiple integer overflows in libgfortran might allow remote attackers to execute arbitrary code or cause a denial of service (Fortran application crash) via vectors related to array allocation. Múltiples desbordamientos de enteros en libgfortran podrían permitir que atacantes remotos ejecuten código arbitrario o provoquen una denegación de servicio (cierre inesperado de la aplicación Fortran) mediante vectores relacionados con la asignación de arrays. • http://www.openwall.com/lists/oss-security/2014/07/24/1 http://www.openwall.com/lists/oss-security/2014/07/31/6 https://bugzilla.redhat.com/show_bug.cgi?id=1122812 https://exchange.xforce.ibmcloud.com/vulnerabilities/94849 https://gcc.gnu.org/viewcvs/gcc/trunk/libgfortran/ChangeLog?limit_changes=0&view=markup&pathrev=211721 • CWE-190: Integer Overflow or Wraparound •
CVSS: 4.3EPSS: 0%CPEs: 1EXPL: 0CVE-2014-8155 – gnutls: gnutls does not perform date/time checks on CA certificates
https://notcve.org/view.php?id=CVE-2014-8155
GnuTLS before 2.9.10 does not verify the activation and expiration dates of CA certificates, which allows man-in-the-middle attackers to spoof servers via a certificate issued by a CA certificate that is (1) not yet valid or (2) no longer valid. Vulnerabilidad en GnuTLS en versiones anteriores a 2.9.10, no verifica las fechas de activación y expiración de certificados CA, lo que permite a atacantes man-in-the-middle suplantar servidores a través de un certificado expedido por un certificado CA que (1) aún no es válido o (2) ya no es válido. It was found that GnuTLS did not check activation and expiration dates of CA certificates. This could cause an application using GnuTLS to incorrectly accept a certificate as valid when its issuing CA is already expired. • http://rhn.redhat.com/errata/RHSA-2015-1457.html http://www.securityfocus.com/bid/73317 https://gitlab.com/gnutls/gnutls/commit/897cbce62c0263a498088ac3e465aa5f05f8719c https://support.f5.com/csp/article/K53330207 https://access.redhat.com/security/cve/CVE-2014-8155 https://bugzilla.redhat.com/show_bug.cgi?id=1197995 • CWE-17: DEPRECATED: Code CWE-325: Missing Cryptographic Step •
CVSS: 5.0EPSS: 0%CPEs: 1EXPL: 0CVE-2015-0282 – gnutls: RSA PKCS#1 signature verification forgery
https://notcve.org/view.php?id=CVE-2015-0282
GnuTLS before 3.1.0 does not verify that the RSA PKCS #1 signature algorithm matches the signature algorithm in the certificate, which allows remote attackers to conduct downgrade attacks via unspecified vectors. GnuTLS anterior a 3.1.0 no verifica que el algoritmo de firmas RSA PKCS #1 coincide con el algoritmo de firmas en el certificado, lo que permite a atacantes remotos realizar ataques de degradación a través de vectores no especificados. It was found that GnuTLS did not verify whether a hashing algorithm listed in a signature matched the hashing algorithm listed in the certificate. An attacker could create a certificate that used a different hashing algorithm than it claimed, possibly causing GnuTLS to use an insecure, disallowed hashing algorithm during certificate verification. • http://rhn.redhat.com/errata/RHSA-2015-1457.html http://www.debian.org/security/2015/dsa-3191 http://www.gnutls.org/security.html http://www.securityfocus.com/bid/73119 http://www.securitytracker.com/id/1032148 https://access.redhat.com/security/cve/CVE-2015-0282 https://bugzilla.redhat.com/show_bug.cgi?id=1194371 • CWE-295: Improper Certificate Validation CWE-310: Cryptographic Issues •

https://notcve.org/view.php?id=CVE-2015-0294
GnuTLS before 3.3.13 does not validate that the signature algorithms match when importing a certificate. GnuTLS versiones anteriores a 3.3.13, no comprueba que los algoritmos de firma coincidan cuando se importa un certificado. It was discovered that GnuTLS did not check if all sections of X.509 certificates indicate the same signature algorithm. This flaw, in combination with a different flaw, could possibly lead to a bypass of the certificate signature check. • http://www.debian.org/security/2015/dsa-3191 https://bugzilla.redhat.com/show_bug.cgi?id=1196323 https://gitlab.com/gnutls/gnutls/commit/6e76e9b9fa845b76b0b9a45f05f4b54a052578ff https://access.redhat.com/security/cve/CVE-2015-0294 • CWE-295: Improper Certificate Validation •
CVSS: 5.0EPSS: 1%CPEs: 9EXPL: 2CVE-2014-8121 – glibc: Unexpected closing of nss_files databases after lookups causes denial of service
https://notcve.org/view.php?id=CVE-2014-8121
DB_LOOKUP in nss_files/files-XXX.c in the Name Service Switch (NSS) in GNU C Library (aka glibc or libc6) 2.21 and earlier does not properly check if a file is open, which allows remote attackers to cause a denial of service (infinite loop) by performing a look-up on a database while iterating over it, which triggers the file pointer to be reset. DB_LOOKUP en nss_files/files-XXX.c en Name Service Switch (NSS) en GNU C Library (también conocida como glibc o libc6) 2.21 y versiones anteriores no comprueba correctamente si un archivo está abierto, lo que permite a atacantes remotos causar una denegación de servicio (bucle infinito) realizando una búsqueda en una base de datos mientras itera sobre ella, lo que desencadena que el puntero al archivo sea reestablecido. It was found that the files back end of Name Service Switch (NSS) did not isolate iteration over an entire database from key-based look-up API calls. An application performing look-ups on a database while iterating over it could enter an infinite loop, leading to a denial of service. • http://lists.opensuse.org/opensuse-security-announce/2015-08/msg00019.html http://lists.opensuse.org/opensuse-security-announce/2016-02/msg00036.html http://rhn.redhat.com/errata/RHSA-2015-0327.html http://www.debian.org/security/2016/dsa-3480 http://www.securityfocus.com/bid/73038 http://www.ubuntu.com/usn/USN-2985-1 http://www.ubuntu.com/usn/USN-2985-2 https://bugzilla.redhat.com/show_bug.cgi?id=1165192 https://security.gentoo.org/glsa/201602-02 https://sourcewa • CWE-17: DEPRECATED: Code CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
