CVE-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 •
CVE-2019-9755 – ntfs-3g: heap-based buffer overflow leads to local root privilege escalation
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 •
CVE-2019-3838 – ghostscript: forceput in DefineResource is still accessible (700576)
https://notcve.org/view.php?id=CVE-2019-3838
It was found that the forceput operator could be extracted from the DefineResource method in ghostscript before 9.27. A specially crafted PostScript file could use this flaw in order to, for example, have access to the file system outside of the constrains imposed by -dSAFER. Se ha observado que el operador forceput podía ser extraído del método DefineResource en ghostscript en las versiones anteriores a la 9.27. Un archivo PostScript especialmente manipulado podría explotar este error, por ejemplo, para obtener acceso al sistema de archivos fuera de las restricciones impuestas por -dSAFER.
