CVSS: 8.1EPSS: 2%CPEs: 12EXPL: 1CVE-2019-3878 – mod_auth_mellon: authentication bypass in ECP flow
https://notcve.org/view.php?id=CVE-2019-3878
A vulnerability was found in mod_auth_mellon before v0.14.2. If Apache is configured as a reverse proxy and mod_auth_mellon is configured to only let through authenticated users (with the require valid-user directive), adding special HTTP headers that are normally used to start the special SAML ECP (non-browser based) can be used to bypass authentication. Se ha detectado una vulnerabilidad en mod_auth_mellon, en versiones anteriores a la v0.14.2. Si Apache está configurado como proxy inverso y mod_auth_mellon está configurado para que solo deje acceder a los usuarios autenticados (con la directiva "require valid-user"), la adición de cabeceras HTTP especiales que se suelen emplear para iniciar el SAML ECP especial (no basado en el navegador) puede emplearse para omitir la autenticación. A vulnerability was found in mod_auth_mellon. • https://access.redhat.com/errata/RHBA-2019:0959 https://access.redhat.com/errata/RHSA-2019:0746 https://access.redhat.com/errata/RHSA-2019:0766 https://access.redhat.com/errata/RHSA-2019:0985 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-3878 https://github.com/Uninett/mod_auth_mellon/pull/196 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CNW5YMC5TLWVWNJEY6AIWNSNPRAMWPQJ https://lists.fedoraproject.org/archives/list/package-announce%40lists. • CWE-287: Improper Authentication CWE-305: Authentication Bypass by Primary Weakness •
CVSS: 9.1EPSS: 0%CPEs: 29EXPL: 1CVE-2019-9948 – python: Undocumented local_file protocol allows remote attackers to bypass protection mechanisms
https://notcve.org/view.php?id=CVE-2019-9948
urllib in Python 2.x through 2.7.16 supports the local_file: scheme, which makes it easier for remote attackers to bypass protection mechanisms that blacklist file: URIs, as demonstrated by triggering a urllib.urlopen('local_file:///etc/passwd') call. urllib en Python, en versiones 2.x hasta la 2.7.16, soporta el esquema local_file:, lo que facilita que los atacantes remotos omitan los mecanismos de protección que ponen en lista negra los URI file:, tal y como queda demostrado con una llamada urllib.urlopen('local_file:///etc/passwd'). • http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00092.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00050.html http://packetstormsecurity.com/files/154927/Slackware-Security-Advisory-python-Updates.html http://www.securityfocus.com/bid/107549 https://access.redhat.com/errata/RHSA-2019:1700 https://access.redhat.com/errata/RHSA-2019:2030 https://access.redhat.com/errata/RHSA-2019:3335 https://access.redhat.com/errata/RHSA-2019:3520 https://bugs.python.o • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-749: Exposed Dangerous Method or Function •

https://notcve.org/view.php?id=CVE-2019-9755
An integer underflow issue exists in ntfs-3g 2017.3.23. A local attacker could potentially exploit this by running /bin/ntfs-3g with specially crafted arguments from a specially crafted directory to cause a heap buffer overflow, resulting in a crash or the ability to execute arbitrary code. In installations where /bin/ntfs-3g is a setuid-root binary, this could lead to a local escalation of privileges. Existe un problema de desbordamiento de enteros en ntfs-3g versión 2017.3.23. Un atacante local podría potencialmente aprovechar esto mediante la ejecución del archivo /bin/ntfs-3g con argumentos especialmente creados desde un directorio especialmente creado para causar un desbordamiento del búfer de la pila, lo que resulta en un bloqueo o la capacidad de ejecutar código arbitrario. • https://access.redhat.com/errata/RHBA-2019:3723 https://access.redhat.com/errata/RHSA-2019:2308 https://access.redhat.com/errata/RHSA-2019:3345 https://security.gentoo.org/glsa/202007-45 https://www.tuxera.com/community/release-history https://access.redhat.com/security/cve/CVE-2019-9755 https://bugzilla.redhat.com/show_bug.cgi?id=1691624 • CWE-122: Heap-based Buffer Overflow CWE-191: Integer Underflow (Wrap or Wraparound) CWE-787: Out-of-bounds Write •
