CVSS: 7.5EPSS: 4%CPEs: 18EXPL: 0CVE-2017-7502 – nss: Null pointer dereference when handling empty SSLv2 messages
https://notcve.org/view.php?id=CVE-2017-7502
Null pointer dereference vulnerability in NSS since 3.24.0 was found when server receives empty SSLv2 messages resulting into denial of service by remote attacker. Se ha encontrado una vulnerabilidad de desreferencia de puntero NULL en NSS desde la versión 3.24.0 en la que el servidor recibe mensajes SSLv2 vacíos, lo que da lugar a una denegación de servicio (DoS) por parte de atacantes remotos. A null pointer dereference flaw was found in the way NSS handled empty SSLv2 messages. An attacker could use this flaw to crash a server application compiled against the NSS library. • http://www.debian.org/security/2017/dsa-3872 http://www.oracle.com/technetwork/security-advisory/cpuoct2017-3236626.html http://www.securityfocus.com/bid/98744 http://www.securitytracker.com/id/1038579 https://access.redhat.com/errata/RHSA-2017:1364 https://access.redhat.com/errata/RHSA-2017:1365 https://access.redhat.com/errata/RHSA-2017:1567 https://access.redhat.com/errata/RHSA-2017:1712 https://hg.mozilla.org/projects/nss/rev/55ea60effd0d https://access.redhat.com/security • CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2017-5461
Mozilla Network Security Services (NSS) before 3.21.4, 3.22.x through 3.28.x before 3.28.4, 3.29.x before 3.29.5, and 3.30.x before 3.30.1 allows remote attackers to cause a denial of service (out-of-bounds write) or possibly have unspecified other impact by leveraging incorrect base64 operations. Los servicios de Seguridad de Red de Mozilla (Network Security Services o NSS) en versiones anteriores a la 3.21.4, versiones de las 3.22.x a las 3.28.x anteriores a la 3.28.4, versiones 3.29.x anteriores a la 3.29.5 y versiones 3.30.x anteriores a la 3.30.1 permiten que atacantes remotos provoquen una denegación de servicio (escritura fuera de límites) o que, probablemente, causen otro impacto no especificado aprovechando operaciones en base64 incorrectas. An out-of-bounds write flaw was found in the way NSS performed certain Base64-decoding operations. An attacker could use this flaw to create a specially crafted certificate which, when parsed by NSS, could cause it to crash or execute arbitrary code, using the permissions of the user running an application compiled against the NSS library. • http://www.debian.org/security/2017/dsa-3831 http://www.debian.org/security/2017/dsa-3872 http://www.oracle.com/technetwork/security-advisory/cpujan2018-3236628.html http://www.oracle.com/technetwork/security-advisory/cpuoct2017-3236626.html http://www.securityfocus.com/bid/98050 http://www.securitytracker.com/id/1038320 https://access.redhat.com/errata/RHSA-2017:1100 https://access.redhat.com/errata/RHSA-2017:1101 https://access.redhat.com/errata/RHSA-2017:1102 https://access. • CWE-787: Out-of-bounds Write •
