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. It was found that the .buildfont1 procedure did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. • http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commitdiff%3Bh=5b85ddd19 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-10216 https://security.gentoo.org/glsa/202004-03 https://access.redhat.com/security/cve/CVE-2019-10216 https://bugzilla.redhat.com/show_bug.cgi?id=1737080 • CWE-648: Incorrect Use of Privileged APIs •
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 •
CVE-2019-10182 – icedtea-web: path traversal while processing <jar/> elements of JNLP files results in arbitrary file overwrite
https://notcve.org/view.php?id=CVE-2019-10182
It was found that icedtea-web though 1.7.2 and 1.8.2 did not properly sanitize paths from <jar/> elements in JNLP files. An attacker could trick a victim into running a specially crafted application and use this flaw to upload arbitrary files to arbitrary locations in the context of the user. Se descubrió que icedtea-web, aunque 1.7.2 y 1.8.2 no desinfectaban correctamente las rutas de los elementos en los archivos JNLP.

CVE-2018-16871 – kernel: nfs: NULL pointer dereference due to an anomalized NFS message sequence
https://notcve.org/view.php?id=CVE-2018-16871
A flaw was found in the Linux kernel's NFS implementation, all versions 3.x and all versions 4.x up to 4.20. An attacker, who is able to mount an exported NFS filesystem, is able to trigger a null pointer dereference by using an invalid NFS sequence. This can panic the machine and deny access to the NFS server. Any outstanding disk writes to the NFS server will be lost. Se detectó un fallo en la implementación de NFS del kernel de Linux, todas las versiones 3.x y todas las versiones 4.x hasta 4.20. • https://access.redhat.com/errata/RHSA-2019:2696 https://access.redhat.com/errata/RHSA-2019:2730 https://access.redhat.com/errata/RHSA-2020:0740 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-16871 https://security.netapp.com/advisory/ntap-20211004-0002 https://support.f5.com/csp/article/K18657134 https://support.f5.com/csp/article/K18657134?utm_source=f5support&%3Butm_medium=RSS https://access.redhat.com/security/cve/CVE-2018-16871 https://bugzilla.redhat.com/show_b • CWE-476: NULL Pointer Dereference •
CVE-2019-2879 – mysql: InnoDB unspecified vulnerability (CPU Jul 2019)
