CVSS: 8.8EPSS: 0%CPEs: 10EXPL: 1CVE-2020-7065 – mb_strtolower (UTF-32LE): stack-buffer-overflow at php_unicode_tolower_full
https://notcve.org/view.php?id=CVE-2020-7065
In PHP versions 7.3.x below 7.3.16 and 7.4.x below 7.4.4, while using mb_strtolower() function with UTF-32LE encoding, certain invalid strings could cause PHP to overwrite stack-allocated buffer. This could lead to memory corruption, crashes and potentially code execution. En PHP versiones 7.3.x por debajo de 7.3.16 y versiones 7.4.x por debajo de 7.4.4, mientras se usa la función mb_strtolower() con codificación UTF-32LE, determinadas cadenas no comprobadas pueden causar que PHP sobrescriba el búfer asignado de la pila. Esto podría conllevar a una corrupción de la memoria, bloqueos y potencialmente a una ejecución de código. A vulnerability was found in PHP while using the mb_strtolower() function with UTF-32LE encoding, where certain invalid strings cause PHP to overwrite the stack-allocated buffer. • https://bugs.php.net/bug.php?id=79371 https://security.netapp.com/advisory/ntap-20200403-0001 https://usn.ubuntu.com/4330-1 https://usn.ubuntu.com/4330-2 https://www.debian.org/security/2020/dsa-4719 https://www.oracle.com/security-alerts/cpuoct2021.html https://www.php.net/ChangeLog-7.php#7.4.4 https://www.tenable.com/security/tns-2021-14 https://access.redhat.com/security/cve/CVE-2020-7065 https://bugzilla.redhat.com/show_bug.cgi?id=1820627 • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •

CVSS: 5.4EPSS: 0%CPEs: 9EXPL: 1CVE-2020-10942 – kernel: vhost-net: stack overflow in get_raw_socket while checking sk_family field
https://notcve.org/view.php?id=CVE-2020-10942
In the Linux kernel before 5.5.8, get_raw_socket in drivers/vhost/net.c lacks validation of an sk_family field, which might allow attackers to trigger kernel stack corruption via crafted system calls. En el kernel de Linux versiones anteriores a 5.5.8, la función get_raw_socket en el archivo drivers/vhost/net.c carece de una comprobación de un campo sk_family, que podría permitir a atacantes desencadenar una corrupción de pila del kernel por medio de llamadas de sistema diseñadas. A stack buffer overflow issue was found in the get_raw_socket() routine of the Host kernel accelerator for virtio net (vhost-net) driver. It could occur while doing an ictol(VHOST_NET_SET_BACKEND) call, and retrieving socket name in a kernel stack variable via get_raw_socket(). A user able to perform ioctl(2) calls on the '/dev/vhost-net' device may use this flaw to crash the kernel resulting in DoS issue. • http://lists.opensuse.org/opensuse-security-announce/2020-04/msg00035.html http://www.openwall.com/lists/oss-security/2020/04/15/4 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.5.8 https://git.kernel.org/linus/42d84c8490f9f0931786f1623191fcab397c3d64 https://lists.debian.org/debian-lts-announce/2020/06/msg00011.html https://lists.debian.org/debian-lts-announce/2020/06/msg00012.html https://lists.debian.org/debian-lts-announce/2020/06/msg00013.html https://lkml.org/lkm • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •

Squid before 4.9, when certain web browsers are used, mishandles HTML in the host (aka hostname) parameter to cachemgr.cgi. Squid versiones anteriores a 4.9, cuando determinados navegadores web son usados, maneja inapropiadamente HTML en el parámetro host (también se conoce como hostname) en el archivo cachemgr.cgi.

The fix for the Linux kernel in Ubuntu 18.04 LTS for CVE-2019-14615 ("The Linux kernel did not properly clear data structures on context switches for certain Intel graphics processors.") was discovered to be incomplete, meaning that in versions of the kernel before 4.15.0-91.92, an attacker could use this vulnerability to expose sensitive information. Se detectó que la solución para el kernel de Linux en Ubuntu versión 18.04 LTS para CVE-2019-14615 ("El kernel de Linux no borró apropiadamente las estructuras de datos en los conmutadores de contexto para determinados procesadores gráficos de Intel") estaba incompleta, lo que significa que en las versiones de kernel anteriores a 4.15.0-91.92, un atacante podría usar esta vulnerabilidad para exponer información confidencial. • https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1862840 https://security.netapp.com/advisory/ntap-20200430-0004 https://usn.ubuntu.com/usn/usn-4302-1 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
