CVE-2018-12387 – Mozilla: stack out-of-bounds read in Array.prototype.push
https://notcve.org/view.php?id=CVE-2018-12387
A vulnerability where the JavaScript JIT compiler inlines Array.prototype.push with multiple arguments that results in the stack pointer being off by 8 bytes after a bailout. This leaks a memory address to the calling function which can be used as part of an exploit inside the sandboxed content process. This vulnerability affects Firefox ESR < 60.2.2 and Firefox < 62.0.3. Vulnerabilidad por la cual el compilador JIT de JavaScript inserta Array.prototype.push con múltiples argumentos que resultan en que el puntero de la pila está fuera de su sitio por 8 bytes tras un bailout. Esto filtra una dirección de memoria a la función llamante que puede emplearse como parte de un exploit dentro del proceso de contenido en sandbox. • http://www.securityfocus.com/bid/105460 http://www.securitytracker.com/id/1041770 https://access.redhat.com/errata/RHSA-2018:2881 https://access.redhat.com/errata/RHSA-2018:2884 https://bugzilla.mozilla.org/show_bug.cgi?id=1493903 https://security.gentoo.org/glsa/201810-01 https://usn.ubuntu.com/3778-1 https://www.debian.org/security/2018/dsa-4310 https://www.mozilla.org/security/advisories/mfsa2018-24 https://access.redhat.com/security/cve/CVE-2018-12387 https:/ • CWE-20: Improper Input Validation CWE-125: Out-of-bounds Read •
CVE-2018-12386 – Mozilla: type confusion in JavaScript
https://notcve.org/view.php?id=CVE-2018-12386
A vulnerability in register allocation in JavaScript can lead to type confusion, allowing for an arbitrary read and write. This leads to remote code execution inside the sandboxed content process when triggered. This vulnerability affects Firefox ESR < 60.2.2 and Firefox < 62.0.3. Una vulnerabilidad en la asignación de registros en JavaScript puede conducir a una confusión de tipos que permite la lectura y escritura arbitrarias. Esto conduce a la ejecución remota de código en el proceso de contenido en sandbox cuando se desencadena. • http://www.securityfocus.com/bid/105460 http://www.securitytracker.com/id/1041770 https://access.redhat.com/errata/RHSA-2018:2881 https://access.redhat.com/errata/RHSA-2018:2884 https://bugzilla.mozilla.org/show_bug.cgi?id=1493900 https://security.gentoo.org/glsa/201810-01 https://usn.ubuntu.com/3778-1 https://www.debian.org/security/2018/dsa-4310 https://www.mozilla.org/security/advisories/mfsa2018-24 https://access.redhat.com/security/cve/CVE-2018-12386 https:/ • CWE-704: Incorrect Type Conversion or Cast CWE-787: Out-of-bounds Write •
CVE-2018-14650 – sos-collector: incorrect permissions set on newly created files
https://notcve.org/view.php?id=CVE-2018-14650
It was discovered that sos-collector does not properly set the default permissions of newly created files, making all files created by the tool readable by any local user. A local attacker may use this flaw by waiting for a legit user to run sos-collector and steal the collected data in the /var/tmp directory. Se ha descubierto que sos-collector no establece correctamente los permisos por defecto de los nuevos archivos creados, haciendo que todos los archivos creados por la herramienta puedan ser leídos por cualquier usuario local. Un atacante local podría utilizar este error esperando a que un usuario legítimo ejecute sos-collector y robe los datos recopilados en el directorio /var/tmp. • https://access.redhat.com/errata/RHSA-2018:3663 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14650 https://github.com/sosreport/sos-collector/commit/72058f9253e7ed8c7243e2ff76a16d97b03d65ed https://access.redhat.com/security/cve/CVE-2018-14650 https://bugzilla.redhat.com/show_bug.cgi?id=1633243 • CWE-276: Incorrect Default Permissions CWE-732: Incorrect Permission Assignment for Critical Resource •
CVE-2018-11763 – Apache2 mod_http2 header Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-11763
In Apache HTTP Server 2.4.17 to 2.4.34, by sending continuous, large SETTINGS frames a client can occupy a connection, server thread and CPU time without any connection timeout coming to effect. This affects only HTTP/2 connections. A possible mitigation is to not enable the h2 protocol. En Apache HTTP Server, de la versión 2.4.17 a la 2.4.34, mediante el envío continuo de tramas SETTINGS grandes, un cliente puede ocupar una conexión, hilo del servidor y tiempo de CPU sin que se active ningún agotamiento del tiempo de conexión. Esto solo afecta a las conexiones HTTP/2. • http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00030.html http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00056.html http://www.securityfocus.com/bid/105414 http://www.securitytracker.com/id/1041713 https://access.redhat.com/errata/RHSA-2018:3558 https://access.redhat.com/errata/RHSA-2019:0366 https://access.redhat.com/errata/RHSA-2019:0367 https://httpd.apache.org/security/vulnerabilities_24.html https://lists.apache.org/thread.html/56c2e7cc9deb1c12a843d0dc251ea7f • CWE-20: Improper Input Validation •
CVE-2018-14634 – Linux Kernel 2.6.x / 3.10.x / 4.14.x (RedHat / Debian / CentOS) (x64) - 'Mutagen Astronomy' Local Privilege Escalation
https://notcve.org/view.php?id=CVE-2018-14634
An integer overflow flaw was found in the Linux kernel's create_elf_tables() function. An unprivileged local user with access to SUID (or otherwise privileged) binary could use this flaw to escalate their privileges on the system. Kernel versions 2.6.x, 3.10.x and 4.14.x are believed to be vulnerable. Se ha encontrado un error de desbordamiento de enteros en la función create_elf_tables() del kernel de Linux. Un usuario local sin privilegios con acceso al binario SUID (o a otro privilegiado) podría emplear este error para escalar sus privilegios en el sistema. • https://www.exploit-db.com/exploits/45516 http://www.openwall.com/lists/oss-security/2021/07/20/2 http://www.securityfocus.com/bid/105407 https://access.redhat.com/errata/RHSA-2018:2748 https://access.redhat.com/errata/RHSA-2018:2763 https://access.redhat.com/errata/RHSA-2018:2846 https://access.redhat.com/errata/RHSA-2018:2924 https://access.redhat.com/errata/RHSA-2018:2925 https://access.redhat.com/errata/RHSA-2018:2933 https://access.redhat.com/errata/RHSA- • CWE-190: Integer Overflow or Wraparound •
