CVSS: 7.5EPSS: 8%CPEs: 4EXPL: 1CVE-2019-1788 – ClamAV OLE2 File Out-Of-Bounds Write Vulnerability
https://notcve.org/view.php?id=CVE-2019-1788
A vulnerability in the Object Linking & Embedding (OLE2) file scanning functionality of Clam AntiVirus (ClamAV) Software versions 0.101.1 and prior could allow an unauthenticated, remote attacker to cause a denial of service condition on an affected device. The vulnerability is due to a lack of proper input and validation checking mechanisms for OLE2 files sent an affected device. An attacker could exploit this vulnerability by sending malformed OLE2 files to the device running an affected version ClamAV Software. An exploit could allow the attacker to cause an out-of-bounds write condition, resulting in a crash that could result in a denial of service condition on an affected device. Una vulnerabilidad en la funcionalidad de análisis de archivos Object Linking & Embedding (OLE2) de las versiones 0.101.1 y anteriores del software Clam AntiVirus (ClamAV) podría permitir que un atacante remoto no autenticado cause una condición de denegación de servicio en un dispositivo afectado. • http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00062.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00064.html https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=12166 https://lists.debian.org/debian-lts-announce/2019/04/msg00019.html https://security.gentoo.org/glsa/201904-12 • CWE-20: Improper Input Validation CWE-787: Out-of-bounds Write •
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-2019-3838
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.
