CVSS: 8.0EPSS: 0%CPEs: 88EXPL: 3CVE-2019-14816 – kernel: heap overflow in mwifiex_update_vs_ie() function of Marvell WiFi driver
https://notcve.org/view.php?id=CVE-2019-14816
There is heap-based buffer overflow in kernel, all versions up to, excluding 5.3, in the marvell wifi chip driver in Linux kernel, that allows local users to cause a denial of service(system crash) or possibly execute arbitrary code. Se presenta un desbordamiento del búfer en la región heap de la memoria en el kernel, todas las versiones hasta 5.3 (excluyéndola), en el controlador de chip wifi marvell en el kernel de Linux, que permite a usuarios locales causar una denegación de servicio (bloqueo del sistema) o posiblemente ejecutar código arbitrario. A vulnerability was found in the Linux kernel's Marvell WiFi chip driver. Where, while parsing vendor-specific informational attributes, an attacker on the same WiFi physical network segment could cause a system crash, resulting in a denial of service, or potentially execute arbitrary code. This flaw affects the network interface at the most basic level meaning the attacker only needs to affiliate with the same network device as the vulnerable system to create an attack path. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00064.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00066.html http://packetstormsecurity.com/files/154951/Kernel-Live-Patch-Security-Notice-LSN-0058-1.html http://packetstormsecurity.com/files/155212/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://www.openwall.com/lists/oss-security/2019/08/28/1 https://access.redhat.com/errata/RHSA-2020:0174 https://access.redhat.com/errata/RHSA-2020:0204&# • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

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 •

A security vulnerability in HPE IceWall SSO Agent Option and IceWall MFA (Agent module ) could be exploited remotely to cause a denial of service. The versions and platforms of Agent Option modules that are impacted are as follows: 10.0 for Apache 2.2 on RHEL 5 and 6, 10.0 for Apache 2.4 on RHEL 7, 10.0 for Apache 2.4 on HP-UX 11i v3, 10.0 for IIS on Windows, 11.0 for Apache 2.4 on RHEL 7, MFA Proxy 4.0 (Agent module only) for Apache 2.4 on RHEL 7. Una vulnerabilidad de seguridad en IceWall SSO Agent Option y IceWall MFA (módulo Agent) de HPE podría ser explotada remotamente para causar una denegación de servicio. Las versiones y plataformas de los módulos Agent Option que están afectadas son las siguientes: versión 10.0 para Apache versión 2.2 en RHEL versiones 5 y 6.0, versión 10.0 para Apache versión 2.4 en RHEL versión 7, versión 10.0 para Apache versión 2.4 en HP-UX 11i versión v3, versión 10.0 para IIS en Windows, versión 11.0 para Apache versión 2.4 en RHEL versión 7, MFA Proxy versión 4.0 (solo módulo Agent) para Apache versión 2.4 en RHEL versión 7. • https://support.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_na-hpesbmu03941en_us •
CVSS: 7.8EPSS: 97%CPEs: 91EXPL: 0CVE-2019-11477 – Integer overflow in TCP_SKB_CB(skb)->tcp_gso_segs
https://notcve.org/view.php?id=CVE-2019-11477
Jonathan Looney discovered that the TCP_SKB_CB(skb)->tcp_gso_segs value was subject to an integer overflow in the Linux kernel when handling TCP Selective Acknowledgments (SACKs). A remote attacker could use this to cause a denial of service. This has been fixed in stable kernel releases 4.4.182, 4.9.182, 4.14.127, 4.19.52, 5.1.11, and is fixed in commit 3b4929f65b0d8249f19a50245cd88ed1a2f78cff. Jonathan Looney detectó que el valor TCP_SKB_CB(skb)-mayor que tcp_gso_segs estuvo sujeto a un desbordamiento de enteros en el kernel de Linux durante el manejo del Reconocimiento Selectivo (SACK) de TCP. Un atacante remoto podría usar esto para causar una denegación de servicio. • http://packetstormsecurity.com/files/153346/Kernel-Live-Patch-Security-Notice-LSN-0052-1.html http://packetstormsecurity.com/files/154951/Kernel-Live-Patch-Security-Notice-LSN-0058-1.html http://www.arubanetworks.com/assets/alert/ARUBA-PSA-2020-010.txt http://www.huawei.com/en/psirt/security-advisories/huawei-sa-20191225-01-kernel-en http://www.openwall.com/lists/oss-security/2019/06/20/3 http://www.openwall.com/lists/oss-security/2019/06/28/2 http://www.openwall.com/lists/oss&# • CWE-190: Integer Overflow or Wraparound CWE-400: Uncontrolled Resource Consumption •
