In verify_emsa_pkcs1_signature() in gmp_rsa_public_key.c in the gmp plugin in strongSwan 4.x and 5.x before 5.7.0, the RSA implementation based on GMP does not reject excess data after the encoded algorithm OID during PKCS#1 v1.5 signature verification. Similar to the flaw in the same version of strongSwan regarding digestAlgorithm.parameters, a remote attacker can forge signatures when small public exponents are being used, which could lead to impersonation when only an RSA signature is used for IKEv2 authentication. En verify_emsa_pkcs1_signature() en gmp_rsa_public_key.c en el plugin gmp en strongSwan en versiones 4.x y 5.x anteriores a la 5.7.0, la implementación RSA basada en GMP no rechaza los datos sobrantes tras el algoritmo OID cifrado durante la verificación de firmas PKCS#1 v1.5. De forma similar al error en la misma versión de strongSwan relacionado con digestAlgorithm.parameters, un atacante remoto puede falsificar firmas cuando se emplean pequeños exponentes públicos, lo que podría conducir a una suplantación cuando solo se emplea una firma RSA para la autenticación IKEv2. • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00077.html http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00047.html https://lists.debian.org/debian-lts-announce/2018/09/msg00032.html https://security.gentoo.org/glsa/201811-16 https://usn.ubuntu.com/3771-1 https://www.debian.org/security/2018/dsa-4305 https://www.strongswan.org/blog/2018/09/24/strongswan-vulnerability-%28cve-20 • CWE-347: Improper Verification of Cryptographic Signature •

https://notcve.org/view.php?id=CVE-2018-12385
A potentially exploitable crash in TransportSecurityInfo used for SSL can be triggered by data stored in the local cache in the user profile directory. This issue is only exploitable in combination with another vulnerability allowing an attacker to write data into the local cache or from locally installed malware. This issue also triggers a non-exploitable startup crash for users switching between the Nightly and Release versions of Firefox if the same profile is used. This vulnerability affects Thunderbird < 60.2.1, Firefox ESR < 60.2.1, and Firefox < 62.0.2. Un cierre inesperado potencialmente explotable en TransportSecurityInfo empleado para SSL puede desencadenarse por los datos almacenados en la caché local en el directorio de perfil del usuario. • http://www.securityfocus.com/bid/105380 http://www.securitytracker.com/id/1041700 http://www.securitytracker.com/id/1041701 https://access.redhat.com/errata/RHSA-2018:2834 https://access.redhat.com/errata/RHSA-2018:2835 https://access.redhat.com/errata/RHSA-2018:3403 https://access.redhat.com/errata/RHSA-2018:3458 https://bugzilla.mozilla.org/show_bug.cgi?id=1490585 https://lists.debian.org/debian-lts-announce/2018/11/msg00011.html https://security.gentoo.org/glsa/201810- • CWE-20: Improper Input Validation CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 7.5EPSS: 0%CPEs: 16EXPL: 0CVE-2018-14647 – python: Missing salt initialization in _elementtree.c module
https://notcve.org/view.php?id=CVE-2018-14647
Python's elementtree C accelerator failed to initialise Expat's hash salt during initialization. This could make it easy to conduct denial of service attacks against Expat by constructing an XML document that would cause pathological hash collisions in Expat's internal data structures, consuming large amounts CPU and RAM. The vulnerability exists in Python versions 3.7.0, 3.6.0 through 3.6.6, 3.5.0 through 3.5.6, 3.4.0 through 3.4.9, 2.7.0 through 2.7.15. El acelerador de C elementtree en Python no inicializa la sal del hash Expat durante la inicialización. Esto podría facilitar llevar a cabo ataques de denegación de servicio (DoS) contra Expat construyendo un documento XML que provocaría colisiones de hashes en las estructuras internas de datos de Expat, consumiendo grandes cantidades de CPU y RAM. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00040.html http://www.securityfocus.com/bid/105396 http://www.securitytracker.com/id/1041740 https://access.redhat.com/errata/RHSA-2019:1260 https://access.redhat.com/errata/RHSA-2019:2030 https://access.redhat.com/errata/RHSA-2019:3725 https://bugs.python.org/issue34623 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14647 https://lists.apache.org/thread.html/r1b103833cb5bc8466e24ff0ecc5e75b45a705334ab6a444e64e840a0%40%3Cissues.boo • CWE-335: Incorrect Usage of Seeds in Pseudo-Random Number Generator (PRNG) CWE-665: Improper Initialization CWE-909: Missing Initialization of Resource •
