CVSS: 5.1EPSS: 0%CPEs: 15EXPL: 1CVE-2018-0495 – ROHNP: Key Extraction Side Channel in Multiple Crypto Libraries
https://notcve.org/view.php?id=CVE-2018-0495
Libgcrypt before 1.7.10 and 1.8.x before 1.8.3 allows a memory-cache side-channel attack on ECDSA signatures that can be mitigated through the use of blinding during the signing process in the _gcry_ecc_ecdsa_sign function in cipher/ecc-ecdsa.c, aka the Return Of the Hidden Number Problem or ROHNP. To discover an ECDSA key, the attacker needs access to either the local machine or a different virtual machine on the same physical host. Libgcrypt en versiones anteriores a la 1.7.10 y versiones 1.8.x anteriores a la 1.8.3 permite un ataque de canal lateral por caché de memoria en las firmas ECDSA que se puede mitigar mediante el uso de la ocultación durante el proceso de firmado en la función _gcry_ecc_ecdsa_sign en cipher/ecc-ecdsa.c. Esto también se conoce como Return Of the Hidden Number Problem o ROHNP. Para descubrir una clave ECDSA, el atacante necesita acceso a la máquina local o a una máquina virtual diferente en el mismo host físico. • http://www.securitytracker.com/id/1041144 http://www.securitytracker.com/id/1041147 https://access.redhat.com/errata/RHSA-2018:3221 https://access.redhat.com/errata/RHSA-2018:3505 https://access.redhat.com/errata/RHSA-2019:1296 https://access.redhat.com/errata/RHSA-2019:1297 https://access.redhat.com/errata/RHSA-2019:1543 https://access.redhat.com/errata/RHSA-2019:2237 https://dev.gnupg.org/T4011 https://git.gnupg.org/cgi-bin/gitweb.cgi?p=libgcrypt.git%3Ba=commit%3 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-203: Observable Discrepancy •
CVSS: 9.8EPSS: 1%CPEs: 17EXPL: 0CVE-2015-7182 – nss: ASN.1 decoder heap overflow when decoding constructed OCTET STRING that mixes indefinite and definite length encodings (MFSA 2015-133)
https://notcve.org/view.php?id=CVE-2015-7182
Heap-based buffer overflow in the ASN.1 decoder in Mozilla Network Security Services (NSS) before 3.19.2.1 and 3.20.x before 3.20.1, as used in Firefox before 42.0 and Firefox ESR 38.x before 38.4 and other products, allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via crafted OCTET STRING data. Desbordamiento de buffer basado en memoria dinámica en el decodificador ASN.1 en Mozilla Network Security Services (NSS) en versiones anteriores a 3.19.2.1 y 3.20.x en versiones anteriores a 3.20.1, como se utiliza en Firefox en versiones anteriores a 42.0 y Firefox ESR 38.x en versiones anteriores a 38.4 y otros productos, permite a atacantes remotos provocar una denegación de servicio (caída de la aplicación) o posiblemente ejecutar código arbitrario a través de datos OCTET STRING manipulados. A heap-based buffer overflow flaw was found in the way NSS parsed certain ASN.1 structures. An attacker could use this flaw to cause NSS to crash or execute arbitrary code with the permissions of the user running an application compiled against the NSS library. • http://lists.opensuse.org/opensuse-security-announce/2015-11/msg00013.html http://lists.opensuse.org/opensuse-security-announce/2015-11/msg00015.html http://lists.opensuse.org/opensuse-security-announce/2015-11/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2015-11/msg00021.html http://lists.opensuse.org/opensuse-security-announce/2015-11/msg00025.html http://lists.opensuse.org/opensuse-updates/2015-12/msg00037.html http://lists.opensuse.org/opensuse-updates/2015-12/msg00049.html http • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow •
CVSS: 5.1EPSS: 0%CPEs: 25EXPL: 0CVE-2013-1620 – nss: TLS CBC padding timing attack
https://notcve.org/view.php?id=CVE-2013-1620
The TLS implementation in Mozilla Network Security Services (NSS) does not properly consider timing side-channel attacks on a noncompliant MAC check operation during the processing of malformed CBC padding, which allows remote attackers to conduct distinguishing attacks and plaintext-recovery attacks via statistical analysis of timing data for crafted packets, a related issue to CVE-2013-0169. La implementación en Mozilla Network Security Services (NSS) de TLS no tiene debidamente en cuenta tiempos de canal lateral ataques a una operación de comprobación de incumplimiento MAC durante el procesamiento de malformaciones relleno CBC, que permite a atacantes remotos para realizar ataques distintivos y los ataques de recuperación de texto plano-a través de análisis estadístico de datos de tiempo de los paquetes hechos a mano, una cuestión relacionada con CVE-2013-0169. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10761 http://lists.opensuse.org/opensuse-security-announce/2013-04/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2013-04/msg00010.html http://openwall.com/lists/oss-security/2013/02/05/24 http://rhn.redhat.com/errata/RHSA-2013-1135.html http://rhn.redhat.com/errata/RHSA-2013-1144.html http://seclists.org/fulldisclosure/2014/Dec/23 http://security.gentoo.org/glsa/glsa-201406-19.xml http://www. • CWE-203: Observable Discrepancy •
