CVE-2019-14813 – ghostscript: Safer mode bypass by .forceput exposure in setsystemparams (701443)
https://notcve.org/view.php?id=CVE-2019-14813
A flaw was found in ghostscript, versions 9.x before 9.50, in the setsystemparams procedure where it did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. A specially crafted PostScript file could disable security protection and then have access to the file system, or execute arbitrary commands. Se detectó un fallo en ghostscript, versiones 9.x versiones anteriores a la 9.50, en el procedimiento setsystemparams donde no aseguraba apropiadamente sus llamadas privilegiadas, permitiendo a los scripts omitir las restricciones "-dSAFER". Un archivo PostScript especialmente diseñado podría deshabilitar la protección de seguridad y entonces tener acceso al sistema de archivos o ejecutar comandos arbitrarios. A flaw was found in the setsystemparams procedure where it did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. • http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commitdiff%3Bh=885444fcbe10dc42787ecb76686c8ee4dd33bf33 http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00088.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00090.html https://access.redhat.com/errata/RHBA-2019:2824 https://access.redhat.com/errata/RHSA-2019:2594 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-14813 https://lists.debian.org/debian-lts-announce/2019/09/msg00007.html https://lists.fedoraproject.o • CWE-648: Incorrect Use of Privileged APIs CWE-863: Incorrect Authorization •
CVE-2019-10092 – Apache Httpd mod_proxy - Error Page Cross-Site Scripting
https://notcve.org/view.php?id=CVE-2019-10092
In Apache HTTP Server 2.4.0-2.4.39, a limited cross-site scripting issue was reported affecting the mod_proxy error page. An attacker could cause the link on the error page to be malformed and instead point to a page of their choice. This would only be exploitable where a server was set up with proxying enabled but was misconfigured in such a way that the Proxy Error page was displayed. En Apache HTTP Server versiones 2.4.0 hasta 2.4.39, se reportó un problema de cross-site scripting limitado que afecta la página de error de mod_proxy. Un atacante podría causar que el enlace sobre la página de error sea malformado y, en su lugar, apunte a una página de su elección. • https://www.exploit-db.com/exploits/47688 https://github.com/mbadanoiu/CVE-2019-10092 http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00004.html http://www.openwall.com/lists/oss-security/2019/08/15/4 http://www.openwall.com/lists/oss-security/2020/08/08/1 http://www.openwall.com/lists/oss-security/2020/08/08/9 https://access.redhat.com/errata/RHSA-2019:4126 https://github.com/DrunkenShells/Disclosures/tree/master/CVE-2019-10092-Limited%20Cross-Site%20 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
CVE-2019-10086 – apache-commons-beanutils: does not suppresses the class property in PropertyUtilsBean by default
https://notcve.org/view.php?id=CVE-2019-10086
In Apache Commons Beanutils 1.9.2, a special BeanIntrospector class was added which allows suppressing the ability for an attacker to access the classloader via the class property available on all Java objects. We, however were not using this by default characteristic of the PropertyUtilsBean. En Apache Commons Beanutils 1.9.2, se agregó una clase especial BeanIntrospector que permite suprimir la capacidad de un atacante para acceder al cargador de clases a través de la propiedad de clase disponible en todos los objetos Java. Sin embargo, no se esta usando esta característica por defecto de PropertyUtilsBean. A flaw was found in the Apache Commons BeanUtils, where the class property in PropertyUtilsBean is not suppressed by default. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00007.html http://mail-archives.apache.org/mod_mbox/www-announce/201908.mbox/%3cC628798F-315D-4428-8CB1-4ED1ECC958E4%40apache.org%3e https://access.redhat.com/errata/RHSA-2019:4317 https://access.redhat.com/errata/RHSA-2020:0057 https://access.redhat.com/errata/RHSA-2020:0194 https://access.redhat.com/errata/RHSA-2020:0804 https://access.redhat.com/errata/RHSA-2020:0805 https://access.redhat.com/errata/RHSA-2020:0806 • CWE-502: Deserialization of Untrusted Data •
CVE-2019-10216 – ghostscript: -dSAFER escape via .buildfont1 (701394)
https://notcve.org/view.php?id=CVE-2019-10216
In ghostscript before version 9.50, the .buildfont1 procedure did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. An attacker could abuse this flaw by creating a specially crafted PostScript file that could escalate privileges and access files outside of restricted areas. En ghostscript anterior a la versión 9.50, el procedimiento .buildfont1 no aseguraba adecuadamente sus llamadas privilegiadas, permitiendo que los scripts eludieran las restricciones `-dSAFER`. Un atacante podría abusar de esta fallo al crear un archivo PostScript especialmente diseñado que podría escalar privilegios y acceder a archivos fuera de las áreas restringidas.

CVE-2019-1125 – Windows Kernel Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2019-1125
An information disclosure vulnerability exists when certain central processing units (CPU) speculatively access memory. An attacker who successfully exploited the vulnerability could read privileged data across trust boundaries. To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted application. The vulnerability would not allow an attacker to elevate user rights directly, but it could be used to obtain information that could be used to try to compromise the affected system further. On January 3, 2018, Microsoft released an advisory and security updates related to a newly-discovered class of hardware vulnerabilities (known as Spectre) involving speculative execution side channels that affect AMD, ARM, and Intel CPUs to varying degrees. This vulnerability, released on August 6, 2019, is a variant of the Spectre Variant 1 speculative execution side channel vulnerability and has been assigned CVE-2019-1125. Microsoft released a security update on July 9, 2019 that addresses the vulnerability through a software change that mitigates how the CPU speculatively accesses memory. Note that this vulnerability does not require a microcode update from your device OEM. • https://www.exploit-db.com/exploits/48071 http://packetstormsecurity.com/files/156337/SWAPGS-Attack-Proof-Of-Concept.html http://www.huawei.com/en/psirt/security-advisories/huawei-sa-20200408-01-swapgs-en https://access.redhat.com/errata/RHBA-2019:2824 https://access.redhat.com/errata/RHBA-2019:3248 https://access.redhat.com/errata/RHSA-2019:2600 https://access.redhat.com/errata/RHSA-2019:2609 https://access.redhat.com/errata/RHSA-2019:2695 https://access.redhat.com/errata/RHS • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
