CVSS: 7.5EPSS: 73%CPEs: 3EXPL: 0CVE-2016-7053 – CMS Null dereference
https://notcve.org/view.php?id=CVE-2016-7053
In OpenSSL 1.1.0 before 1.1.0c, applications parsing invalid CMS structures can crash with a NULL pointer dereference. This is caused by a bug in the handling of the ASN.1 CHOICE type in OpenSSL 1.1.0 which can result in a NULL value being passed to the structure callback if an attempt is made to free certain invalid encodings. Only CHOICE structures using a callback which do not handle NULL value are affected. En OpenSSL 1.1.0 anterior a 1.1.0c, las aplicaciones que analizan estructuras CMS inválidas pueden dejar de dar servicio por una referencia a puntero nulo. Esto se produce por un fallo en la gestión del tipo ASN.1 CHOICE en OpenSSL 1.1.0, lo que puede derivar en que un valor NULL sea enviado a la devolución de la llamada si se intenta utilizar varias codificaciones inválidas. • http://www.securityfocus.com/bid/94244 http://www.securitytracker.com/id/1037261 https://h20566.www2.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_na-hpesbhf03744en_us https://www.openssl.org/news/secadv/20161110.txt • CWE-476: NULL Pointer Dereference •
CVSS: 5.9EPSS: 0%CPEs: 7EXPL: 0CVE-2016-7055 – openssl: Carry propagating bug in Montgomery multiplication
https://notcve.org/view.php?id=CVE-2016-7055
There is a carry propagating bug in the Broadwell-specific Montgomery multiplication procedure in OpenSSL 1.0.2 and 1.1.0 before 1.1.0c that handles input lengths divisible by, but longer than 256 bits. Analysis suggests that attacks against RSA, DSA and DH private keys are impossible. This is because the subroutine in question is not used in operations with the private key itself and an input of the attacker's direct choice. Otherwise the bug can manifest itself as transient authentication and key negotiation failures or reproducible erroneous outcome of public-key operations with specially crafted input. Among EC algorithms only Brainpool P-512 curves are affected and one presumably can attack ECDH key negotiation. • 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/cpuoct2017-3236626.html http://www.securityfocus.com/bid/94242 http://www.securitytracker.com/id/1037261 https://access.redhat.com/errata/RHSA-2018:2185 https://access.redhat.com/errata/RHSA-2018:2186 https://access.redhat.com/errata/RHSA-2018:2187 https://h20566.www2.hpe.com/hpsc/doc/public • CWE-682: Incorrect Calculation •
